Lab Diamond Price: Value, Cost & What Affects Price

Lab diamond price is unusually dynamic because the finished stone combines a standardized physical material with a manufactured supply chain capable of expanding production, improving yields, and introducing large quantities of closely comparable stones. A laboratory-grown diamond is still diamond—crystalline carbon with diamond’s fundamental optical and physical properties—but its market scarcity operates differently from natural diamond. That distinction helps explain why two laboratory-grown diamonds with superficially similar specifications can carry noticeably different asking prices and why prices for equivalent manufactured stones can change as production technology, wholesale supply, retailer inventory, and competition evolve.

The useful way to evaluate lab diamond price is therefore not to memorize one permanent dollar-per-carat figure. It is to normalize the stones being compared. Carat weight, shape, face-up dimensions, color appearance, clarity, cut quality, polish, symmetry, report laboratory, treatment disclosures, growth-related transparency issues, and retailer context all need to be considered before the price difference becomes meaningful. Current market-index data covering hundreds of thousands of laboratory-grown diamonds demonstrate substantial price variation across carat weights and shapes even before individual quality differences are considered.

The market framework on this page is intentionally separate from generic seller selection, which belongs in buy Lab Diamond. The mineral identity and HPHT/CVD distinction are covered in Lab Diamond meaning, while this page owns value methodology, quality bands, size effects, treatment context, retail differences, and documented price comparisons within Buying & Value.

Lab Diamond Price at a Glance

What Is Actually Being Priced?

A loose laboratory-grown diamond price represents more than the carbon crystal. It includes the cost of growing rough, post-growth processing when used, cutting and polishing, laboratory documentation, logistics, inventory financing, retailer overhead, marketing, customer-service infrastructure, and profit margin.

Finished jewelry adds another layer. A ring price can include precious metal, setting labor, side stones, custom design, brand positioning, warranty services, resizing, fulfillment, and retail presentation. Dividing the completed ring price by the center diamond’s carat weight therefore does not produce a meaningful laboratory-grown diamond price per carat.

Even loose stones need normalization. Consider two 2.00 ct round laboratory-grown diamonds with the same stated color and clarity. One may carry excellent proportions and a face-up diameter near the expected range, while another may hide more weight in excess depth. A consumer sorting only by carat can pay more for a stone that does not actually look larger from above.

Cut planning and weight retention are examined separately in Lab Diamond cutting, orientation, and polish. On a price page, the important point is that carat weight is only one part of visible value.

A Documented Market Snapshot

A useful market sample should identify its assumptions rather than pretending that every laboratory-grown diamond of the same weight has one price. The following snapshot combines a large multi-retailer price index with individual fixed-price retail observations. It is intended to demonstrate market structure, not establish permanent valuations.

Broad Multi-Retailer Index

A current laboratory-grown diamond index built from more than 750,000 online listings reports the following representative prices by shape and nominal carat weight. These figures aggregate market listings and therefore do not hold color, clarity, cut proportions, laboratory report, or other quality variables perfectly constant.

What This Sample Shows

First, shape matters. The same nominal carat weight does not produce the same market price across round, oval, emerald, princess, cushion, and pear cuts.

Second, the move from 1 ct to 2 ct or 3 ct does not follow one universal multiplier. Manufacturing supply, cutting yield, demand by shape, and the specific inventory represented in the index all influence the relationship.

Third, an index value is not an appraisal of a particular stone. A beautifully proportioned 2 ct round with superior finish can deserve a different price from a poorly proportioned 2 ct round even when both fall into the same broad index category.

Original Comparable-Stone Sample

Individual listings make those limitations clearer. A specialist online retailer has displayed IGI-reported round laboratory-grown diamonds around 2.00 ct, E color, VS1 clarity, and Ideal cut at retail asking prices ranging from roughly the mid-$900s to above $1,400, despite the specifications appearing very similar at headline level. Other comparable recommendations on those same listings were lower or higher again.

A 1.00 ct D/VS1 Ideal round from the same retail environment was listed at $589, with a recommended comparable stone shown at $432.

These observations should not be read as a permanent price list. Their value is analytical: even after controlling approximately for weight, shape, color, clarity, and broad cut label, the retail spread remains large.

The lesson is not that one of these prices is “correct.” The lesson is that headline grades alone do not explain the complete market price.

Why Lab Diamond Price Changes Faster Than Many Gemstone Guides Suggest

Manufactured-diamond supply can expand when growers add equipment, improve growth cycles, increase usable yield, or reduce post-processing costs. Cutting centers can also process larger volumes of standardized rough.

That means historical price references become stale quickly. A table copied from an old article can look authoritative while reflecting an entirely different supply environment.

A responsible lab diamond price reference therefore needs two components:

1. a methodology that remains useful even when prices change; and
2. a documented live-market sample clearly identified as a snapshot.

The second component should be refreshed periodically rather than presented as permanent truth.

Quality Bands: The Market Is Not One Continuous “Perfect Diamond” Category

Colorless and near-colorless laboratory-grown diamonds are often produced in relatively high color and clarity qualities. GIA changed its evaluation framework for these stones because much manufactured supply occupies a narrower quality range than natural-diamond production.

For current colorless-to-near-colorless laboratory-grown submissions, GIA uses an overall Premium or Standard quality assessment rather than applying its traditional natural-diamond color and clarity nomenclature as the primary consumer-facing description. Premium requires the highest combination of criteria, including D color, VVS or higher clarity, Excellent polish and symmetry, and Excellent cut for qualifying round brilliants. Standard allows a broader combination down through E–J color, VS clarity, Very Good finish criteria, and related minimum requirements. Stones that do not satisfy the minimum Standard criteria do not receive a GIA quality designation.

This does not mean all laboratories use identical terminology. Many retail inventories remain heavily documented by laboratories that provide familiar letter color grades, clarity grades, and cut assessments. A buyer comparing stones therefore needs to understand the report system being used rather than assuming every “grade” is directly interchangeable.

Current GIA Lab-Grown Quality Framework

GIA’s current laboratory-grown services specifically distinguish these assessments from reports for natural diamonds.

That change itself demonstrates why price articles should avoid treating one fixed report vocabulary as permanent.

Does Premium Automatically Mean Best Value?

No.

A Premium-quality laboratory-grown diamond may be technically superior on several grading criteria but still represent poorer value for a particular buyer if the price premium is large and the visible difference is negligible.

For example, moving from an attractive near-colorless, eye-clean Standard stone to a top Premium stone may increase the asking price without creating a proportionate face-up improvement under normal jewelry viewing.

The appropriate question is therefore not “Which label is highest?” but “Which measured improvement am I paying for, and can I actually see or use it?”

This distinction becomes especially important because manufactured stones can make very high nominal color and clarity comparatively accessible.

Cut Can Matter More Than a Small Color or Clarity Upgrade

For a round brilliant, cut proportions affect brightness, fire, scintillation, pattern, weight ratio, and durability. GIA’s diamond cut system evaluates proportions alongside polish and symmetry because a diamond’s performance cannot be reduced to color and clarity alone.

Two stones both called “Ideal” by a retailer or grading ecosystem may nevertheless differ in table size, crown angle, pavilion angle, depth, girdle thickness, face-up spread, and optical pattern.

A lower-priced stone with excellent light return and balanced proportions can therefore represent better visual value than a more expensive stone whose premium comes from a higher clarity grade that is invisible without magnification.

The underlying optical behavior of laboratory-grown diamond is addressed in Lab Diamond optical properties and color behavior.

Size Effect: Total Price Rises, but Price per Carat Is Not Linear

Laboratory-grown diamonds become more expensive in total as carat weight increases, but the relationship does not mimic natural-diamond rarity.

The broad index sample currently places round laboratory-grown diamonds at roughly $502 for 1 ct, $1,188 for 2 ct, and $1,873 for 3 ct. That corresponds to approximate indexed prices per carat of $502, $594, and $624 respectively.

This modest increase is very different from assuming that every additional carat creates an exponential rarity premium.

The pattern also varies by shape. In the same index, some 2 ct fancy shapes were below $1,000 while others exceeded $1,300. Shape-specific cutting yield and demand therefore need to be considered along with size.

Face-Up Size Is More Useful Than Carat Alone

Carat is weight, not visible diameter.

A deeply cut 2 ct round can look smaller from above than a better-spread 2 ct stone because more of its weight is hidden below the girdle. Fancy shapes introduce even more variation because length-to-width ratio affects visual coverage.

This is why dimensions should be part of any price comparison. A buyer paying an extra $250 for 0.10 ct of additional hidden pavilion weight may receive less visible benefit than a buyer paying for better proportions at slightly lower carat weight.

Shape Can Shift Price Significantly

The documented market index shows measurable differences among round, oval, emerald, princess, cushion, and pear laboratory-grown diamonds at the same broad weight categories.

Those differences can reflect:

• cutting yield from laboratory-grown rough;
• demand for the shape;
• inventory abundance;
• proportion standards;
• difficulty of finding attractive optical performance;
• face-up size expectations;
• consumer fashion.

A fancy-shape buyer should therefore compare against the same shape first rather than using round-brilliant prices as the universal benchmark.

Clarity: Paying for Invisible Differences

Laboratory-grown diamond production can yield stones with very high clarity, which can make the upper clarity categories comparatively common in retail inventory.

If two diamonds are both eye-clean at normal viewing distance, paying a substantial premium to move from VS to VVS may add little visual value unless the buyer specifically values the technical grade.

That does not mean clarity is irrelevant. Large dark inclusions, centrally located features, structural weaknesses, transparency-reducing clouds, or conspicuous growth-related characteristics can materially affect appearance and desirability.

Detailed growth features and inclusion evidence belong in the Lab Diamond microscope inclusion notebook rather than being converted into a simplistic statement that one growth method is automatically clearer than another.

Color: Small Grade Differences Versus Actual Appearance

Colorless laboratory-grown diamonds often occupy a narrow high-color range. That makes paying for the highest possible color label less automatically useful than in a market containing wide visible color variation.

A D-color premium can make sense for someone who values the top technical category. Another buyer may prefer a slightly lower color designation that still looks colorless in the intended setting and allocate the savings toward size or cut.

Setting metal matters visually too. A small difference between very high color grades can be even harder to perceive once the stone is mounted in yellow or rose gold.

Fancy-color laboratory-grown diamonds belong to a different valuation framework because color origin, saturation, distribution, growth defects, irradiation, annealing, and other processes become central. Their physical color mechanisms are separated on Lab Diamond color meaning.

Growth Method: HPHT Versus CVD and Price

HPHT and CVD are production methods, not automatic quality grades.

A well-cut, attractive CVD diamond should not be assumed inferior to an HPHT diamond simply because of the growth acronym, and the reverse is equally true. Both methods can produce high-quality material.

Growth method can still matter when the individual stone has visible consequences associated with its growth history—unfavorable color tint, strain, transparency issues, metallic inclusions, graphitic features, or post-growth treatment.

The geological-versus-manufactured origin distinction is detailed in Lab Diamond formation and deposit geology. For price, the rule is simpler: evaluate the finished diamond, not the acronym alone.

Post-Growth Treatment

Laboratory-grown diamonds can undergo post-growth treatment to modify color or improve appearance. HPHT processing may be used after CVD growth, while irradiation and annealing can produce or alter fancy colors.

Treatment is therefore a separate field from growth origin.

A stone can be:

• HPHT-grown without later treatment;
• HPHT-grown and subsequently treated;
• CVD-grown without later treatment;
• CVD-grown and later HPHT processed;
• grown by either method and subsequently color modified through other techniques.

Current GIA colored laboratory-grown diamond services can include assessment of growth type and post-growth treatment, while its colorless-to-near-colorless Premium/Standard service focuses on overall quality classification.

Treatment should matter to price when a seller’s premium depends on a specific untreated or color-origin representation. It should not be treated as automatic proof that the diamond is low quality.

Lab Report Context Can Affect Marketability

A grading or quality-assessment report performs several functions. It identifies the diamond as laboratory-grown, records quality information according to the laboratory’s system, and provides a document that future buyers can verify against the stone.

GIA’s current laboratory-grown quality assessment laser-inscribes qualifying colorless-to-near-colorless stones with “Laboratory-Grown” and the assessment number.

A report does not establish retail value. GIA explicitly distinguishes grading from appraisal in its consumer guidance: laboratory assessment describes characteristics that influence value but is not itself an appraisal.

That distinction matters when a seller says “certified value.” The report may authenticate specifications; it does not certify that the asking price is fair or guarantee resale.

Original Price-Normalization Methodology

Before comparing two lab diamond prices, record the following fields.

This framework turns a product listing into a comparable dataset rather than relying on “1 carat lab diamond price” as though one number applied to every stone.

Example Comparison 1: Same 2 ct Headline Grades, Different Price

Consider two hypothetical 2.00 ct E/VS1 round laboratory-grown diamonds.

Stone A costs $950. It has balanced dimensions, an attractive face-up spread, excellent polish and symmetry, and no obvious undesirable tint.

Stone B costs $1,250. Its headline grades appear identical, but its depth hides additional weight and the face-up diameter is slightly smaller.

If the report data and visual performance support those observations, the more expensive stone does not automatically represent higher value simply because its total price is greater.

The real comparison is visible performance per dollar, not certificate headlines alone.

Example Comparison 2: 1.80 ct Excellent Cut Versus 2.00 ct Weak Spread

Suppose a well-proportioned 1.80 ct round faces up almost as large as a deeply cut 2.00 ct alternative.

If the 1.80 ct stone has stronger brightness, more balanced pattern, and a significantly lower price, the round-number 2.00 ct milestone may provide little practical benefit.

This is one of the clearest situations where carat psychology can cost more than visible size.

Example Comparison 3: VVS Versus VS

Stone A is 2 ct, eye-clean VS1.

Stone B is nearly identical but VVS1 and costs 20% more.

If neither stone shows visible inclusions without magnification, the VVS premium is mainly a technical-quality preference. That can be entirely legitimate, but it should be recognized as such.

A buyer focused on visual value may prefer allocating that premium toward cut quality, size, or setting design.

Example Comparison 4: D Color Versus Near-Colorless Appearance

A D-color laboratory-grown diamond can satisfy a buyer who specifically wants the top color category. Another near-colorless stone may look effectively colorless after mounting while costing less.

Neither purchase is inherently better. The difference is whether the technical grade itself has value to the buyer.

This is why quality bands should describe tradeoffs rather than declare that the highest available grade is automatically the smartest purchase.

Retail Context: Why Similar Diamonds Can Have Very Different Prices

The individual retail sample demonstrates that visually similar headline specifications can sit at noticeably different asking prices. Retail price can contain:

• procurement cost;
• fulfillment cost;
• inventory risk;
• inspection services;
• customer support;
• free returns;
• financing;
• shipping and insurance;
• marketing;
• physical showroom overhead;
• brand positioning;
• retailer markup.

One transparent retailer even publishes diamond cost, fulfillment cost, markup, and final retail price separately on individual listings, demonstrating how much of the consumer price can arise after the stone itself enters the retail chain.

This does not prove that low markup is always best. Service has value. It simply explains why the loose diamond’s material characteristics cannot account for the entire spread.

Generic merchant-selection criteria remain outside this page’s scope and belong on the dedicated purchase guide.

Retail Asking Price Is Not Wholesale Cost

The difference between wholesale manufacturing economics and retail asking price can be substantial. A consumer should not interpret a published wholesale figure or disclosed diamond-acquisition cost as the amount every retailer should charge.

Retail businesses incur legitimate costs after acquiring inventory.

Likewise, a heavily discounted retail listing does not necessarily reveal the manufacturer’s production cost. Clearance, virtual inventory, supplier agreements, customer acquisition strategy, or market competition may all affect the final number.

Asking Price Is Also Not Resale Value

A laboratory-grown diamond purchased at retail should not be treated as a guaranteed store of financial value.

Resale markets operate through different channels and margins. The supply of newly manufactured diamonds can also continue to change, meaning a future buyer may compare a used stone against newly produced alternatives with newer grading reports and potentially lower replacement cost.

For that reason, this page makes no promise that a laboratory-grown diamond will appreciate, retain a fixed percentage of purchase price, or recover its original retail cost.

The site’s broader limitations around price and financial interpretations are stated in the Disclaimer.

Why “Investment Grade Lab Diamond” Needs Scrutiny

“Investment grade” is not a standardized laboratory-grown diamond quality category.

A high-quality diamond can certainly be valuable jewelry, but describing it as an investment implies an expectation about future financial performance. That requires evidence about liquidity, future demand, replacement supply, transaction costs, and resale markets—not simply D color or VVS clarity.

The same caution applies to claims such as “guaranteed appreciation” or “future collectible.”

Collectibility can develop around particular research specimens, unusual colors, historic production, famous provenance, or technological milestones, but none of those creates an automatic financial return.

Colored Lab Diamonds Need a Different Price Framework

A pink, blue, yellow, green, or other fancy-color laboratory-grown diamond should not be priced using the colorless-market index alone.

Fancy-color valuation needs to consider:

• hue;
• tone;
• saturation;
• color distribution;
• growth method;
• post-growth treatment;
• color mechanism;
• cut;
• clarity;
• size;
• report findings.

GIA currently maintains separate laboratory-grown colored-diamond reporting services because the information needed to describe color and treatment differs from the broad Premium/Standard assessment used for colorless-to-near-colorless stones.

Jewelry Setting Costs Can Reverse a “Cheap Diamond” Comparison

Laboratory-grown diamond jewelry sometimes uses a relatively affordable center stone inside an expensive precious-metal or designer setting.

A $700 loose center diamond may end up inside a finished ring costing several times that amount. Comparing the completed ring with another loose stone therefore creates a false impression of the diamond price.

The center stone and mounting should be valued separately whenever possible.

Mechanical setting considerations—including vulnerable points, girdle thickness, prong placement, and impact exposure—are covered in Lab Diamond setting and wear engineering.

Cleaning Does Not Increase Value, but Condition Matters

Diamond is exceptionally scratch resistant, but it can still chip, acquire surface contamination, or suffer damage around vulnerable facet junctions and cleavage directions.

Routine care will not transform a lower-quality diamond into a higher grade, but maintaining a clean stone allows its actual optical performance to remain visible. Severe damage can obviously reduce desirability.

Care procedures are kept on how to clean Lab Diamond jewelry so cleaning advice does not crowd the pricing methodology.

Research or Historic Lab-Grown Specimens Can Be Valued Differently

Most retail laboratory-grown diamonds are priced as gems. Research crystals can operate under another value framework.

An early HPHT crystal, experimental CVD plate, unusual growth-sector specimen, historically significant manufacturer sample, or scientifically documented colored crystal may have research or collection interest independent of jewelry quality.

In those cases, provenance and technical documentation can matter more than the conventional 4Cs.

Record preservation for such material belongs in Lab Diamond specimen conservation record.

The Role of Transparency and Growth Features

A laboratory-grown diamond can possess strong headline grades while showing visual characteristics that matter to an experienced buyer, including gray, blue, or brown nuance, strain patterns, unusual fluorescence, haziness, or growth-related transparency issues.

These observations do not mean one growth method is categorically inferior. They mean the finished stone needs to be examined rather than purchased from spreadsheet grades alone.

Microscopic growth structures and identification clues belong to the inclusion notebook, while price should account only for their actual effect on appearance, report findings, rarity, or buyer preference.

A Practical Lab Diamond Price Workflow

Start with a narrowly defined comparison rather than a universal price-per-carat search.

For example:

Round, 1.90–2.10 ct, colorless/near-colorless quality acceptable to you, eye-clean, strong cut performance, verified laboratory documentation.

Then compare face-up dimensions and proportion data.

Remove stones with undesirable visible tint, haze, poor spread, or obvious optical weakness.

Only then compare asking prices.

This sequence prevents a low price from persuading the buyer to accept a stone that did not meet the original quality requirement.

What Market Data Can and Cannot Tell You

A large market index can answer questions such as:

• What does the current broad price environment look like?
• How does price shift with weight?
• Which shapes are generally cheaper or more expensive?
• Are prices moving significantly?

It cannot answer:

• Is this individual diamond beautiful?
• Is this specific $900 stone better than this $1,100 stone?
• Does one stone have undesirable tint or transparency?
• Will a future buyer pay the same amount?
• Is a particular setting worth its markup?

Individual evaluation remains necessary.

Evidence Limits

The documented prices on this page are market observations, not appraisals. Listings can change, disappear, receive promotions, or be repriced. Indexes also aggregate stones with different quality combinations.

No price example should therefore be interpreted as a promise that another stone of the same weight will sell for the same amount.

Frequently Asked Questions

How much does a lab diamond cost?

There is no single lab diamond price. Current large-scale market data show broad differences by carat weight and shape, with additional variation created by cut, quality, dimensions, report system, treatment context, and retailer.

How much is a 1 carat lab diamond?

In the broad market index reviewed for this article, representative 1 ct prices varied by shape from roughly the high-$400s into the mid-$600s. Individual stones can fall outside that range because quality and retailer context differ.

How much is a 2 carat lab diamond?

The same broad index placed representative 2 ct laboratory-grown diamonds from roughly $990 to nearly $1,400 depending on shape. Individual 2 ct rounds with similar headline quality specifications have also shown substantial retailer-level price variation.

How much is a 3 carat lab diamond?

Broad indexed 3 ct prices in the reviewed sample ranged approximately from the mid-$1,500s to just above $2,000 depending on shape. Individual quality differences can move a particular stone outside those levels.

Why are lab diamond prices so different between sellers?

Retail prices can include different acquisition costs, fulfillment, inventory strategy, inspection, shipping, returns, financing, marketing, physical overhead, customer service, and profit margins. Stone-specific cut and optical differences can also exist even when headline grades match.

Does price per carat increase with size?

Usually total price rises with size, and price per carat can rise too, but the relationship is not uniform. Laboratory production means the size premium does not necessarily behave like natural-diamond rarity.

Which lab diamond shape is cheapest?

There is no permanent cheapest shape. In the live index reviewed here, pricing differed across round, oval, emerald, princess, cushion, and pear shapes, and the ranking changed with carat weight.

Does D color make a lab diamond much more expensive?

It can add a premium, but the practical value depends on whether the visible improvement matters to the buyer. Much colorless laboratory-grown production is already concentrated in high-color categories.

Is VVS worth more than VS in lab diamonds?

Technically yes, but the visible difference may be negligible when both stones are eye-clean. Paying the premium is a quality preference rather than an automatic requirement for a beautiful diamond.

What does GIA Premium mean for a lab-grown diamond?

GIA’s current Premium assessment requires the highest qualifying combination of color, clarity, polish, symmetry, and round-brilliant cut criteria. Standard covers a broader qualifying range.

Does GIA still use normal natural-diamond grades for colorless lab-grown diamonds?

Its current consumer-facing laboratory-grown quality assessment uses Premium and Standard categories for colorless-to-near-colorless laboratory-grown diamonds rather than the traditional natural-diamond grading nomenclature.

Do other laboratories still use color and clarity grades?

Yes. Laboratory-report terminology is not uniform across the market, and many retail laboratory-grown diamonds are sold with reports using familiar color and clarity grades. Buyers should understand which laboratory’s system they are comparing.

Does HPHT cost more than CVD?

Not automatically. Growth method alone does not determine finished-gem quality or price. Evaluate the individual stone’s appearance, cut, report findings, treatment history, and market context.

Does post-growth treatment reduce value?

It can matter when a premium depends on untreated color or a particular production history, especially for fancy colors. In ordinary colorless laboratory-grown diamonds, finished appearance and quality often matter more to most buyers.

Is an IGI or GIA report an appraisal?

No. A grading or quality report describes gemological characteristics and identity. GIA specifically does not provide diamond appraisals through its grading report service.

Does a certificate guarantee that the price is fair?

No. Documentation can verify characteristics, but fair market price is a separate commercial question.

Why can two 2 carat E/VS1 lab diamonds have different prices?

Cut proportions, face-up spread, finish, fluorescence, tint, transparency, growth characteristics, report details, retailer overhead, and inventory strategy can all produce price differences even when headline specifications match.

Should I buy the cheapest lab diamond with the grades I want?

Price should be compared after checking proportions, dimensions, optical appearance, tint, transparency, documentation, and other relevant quality fields. The lowest listed number is not automatically the strongest visual value.

Is a bigger lab diamond always better value?

No. A deeply cut heavier diamond can look smaller than a lighter well-proportioned stone. Face-up dimensions and optical performance should be compared alongside carat weight.

Do lab diamonds hold their value?

There is no guaranteed retention percentage. Resale markets, retailer margins, continuing production, replacement prices, and consumer demand can all change. A retail purchase price should not be treated as guaranteed recoverable value.

Are lab diamonds a good investment?

They should not be purchased on a promise of guaranteed appreciation. An investment claim requires evidence about future market demand, liquidity, transaction costs, and supply that a grading report cannot provide.

Are colored lab diamonds priced the same way as colorless lab diamonds?

No. Fancy-color laboratory-grown diamonds require additional analysis of hue, tone, saturation, color distribution, growth method, and post-growth treatment. GIA provides separate services for laboratory-grown colored diamonds.

Does setting price affect the value of the loose lab diamond?

The setting changes the finished jewelry price but not the loose diamond’s intrinsic gemological characteristics. Metal, design, labor, side stones, brand, and services should be separated when comparing center-stone prices.

How often should lab diamond price guides be updated?

Frequently enough to reflect meaningful changes in current supply and retail pricing. Because the market is manufactured and competitive, old fixed price tables can become misleading faster than a methodology-based guide.
