Lab-grown gemstones look identical to natural ones, cost a fraction of the price, and are chemically the same material — so why does natural still command a premium? It’s one of the most common questions buyers face today, and the honest answer is: it depends on what you value. At Gems Lore, here’s a clear, balanced comparison to help you decide which is right for you.
Quick Verdict
- Choose lab-grown if you want the same look for much less money, prioritize traceable and lower-impact sourcing, and aren’t concerned about resale value.
- Choose natural if you value rarity, tradition, the story of a one-of-a-kind earth-formed stone, and better long-term value retention.
- Either way: both are real gemstones — the key is that the seller discloses which you’re buying.
What Are Lab-Grown Gemstones?
Lab-grown (or “lab-created” / “synthetic”) gemstones are real gems grown in a laboratory rather than the earth. They have the same chemical composition, crystal structure, and physical properties as their natural counterparts — a lab sapphire is genuinely sapphire, a lab diamond is genuinely diamond.
They’re produced by recreating the conditions that form gems naturally, just far faster. Diamonds are grown via HPHT (high pressure, high temperature) or CVD (chemical vapor deposition); colored stones like sapphire, ruby, and emerald are grown through flux and hydrothermal methods.
Crucially, lab-grown stones are not the same as simulants like cubic zirconia or glass, which only look similar but are entirely different materials. (Moissanite is its own case — see our moissanite vs diamond guide.)

What Are Natural Gemstones?
Natural gemstones formed deep in the earth over millions of years and were mined, cut, and polished. Each is genuinely one of a kind, shaped by unrepeatable geological conditions — and that rarity, history, and “miracle of nature” quality is much of what people pay for.
Lab-Grown vs Natural: Side by Side
| Factor | Lab-Grown | Natural |
|---|---|---|
| Composition | Identical to natural | Formed in the earth |
| Is it a “real” gem? | Yes | Yes |
| Appearance | Same; often higher clarity | Natural inclusions common |
| Price | Typically far cheaper | Premium for rarity |
| Rarity | Reproducible | Finite and unique |
| Resale value | Tends to depreciate | Holds value better |
| Sourcing | Traceable, conflict-free | Varies by source |
| Environmental impact | Energy-intensive, but no mining | Mining footprint, but supports livelihoods |
| Availability | Consistent supply | Depends on what’s mined |
The Key Differences Explained
Are They Really the Same?
Materially, yes. Gemologically, a lab-grown stone and a natural stone of the same type are the same substance, with the same hardness, sparkle, and color potential. The differences are about origin, not quality — which is why “lab-grown isn’t real” is a myth.
Price
This is the headline. Lab-grown stones typically cost a large fraction less than natural equivalents — lab-grown diamonds especially have dropped dramatically in price. For the same visible size and quality, lab-grown lets your budget go much further.
Appearance and Quality
Because they’re grown in controlled conditions, lab stones can be very clean and consistent — sometimes higher clarity than affordable natural stones, which more often carry visible inclusions. Some buyers love the flawlessness; others prefer the character of a natural stone.
Rarity and Resale Value
Natural gems are finite and unique, which underpins their value and their tendency to hold worth over time. Lab-grown stones can be made on demand, so they generally depreciate rather than appreciate — lab diamond prices in particular have fallen as production scaled. (This is general information, not financial or investment advice.)
Ethics and Environment
Both sides have a real case. Lab-grown is often chosen as traceable and conflict-free, with no mining disruption — though growing gems is energy-intensive, so it’s not impact-free. Natural mining carries environmental and, historically, ethical concerns, but responsibly sourced stones also support livelihoods in mining communities. Neither is automatically “the ethical choice”; it depends on the specific stone and source.
How to Tell Them Apart
Usually, you can’t by eye — it takes gemological equipment, since the materials are identical. Lab stones may show specific growth features under magnification, and reputable sellers disclose origin on a lab report. This is exactly why certification and disclosure matter so much (see how to buy gemstones online and gemstone certification).
Which Should You Buy?
There’s no universally right answer — only the right answer for you:
- Budget and size matter most? Lab-grown gives you more stone for your money.
- Care about traceable, mining-free sourcing? Lab-grown appeals to many for this reason.
- Value rarity, tradition, and long-term worth? Natural is the classic choice.
- Buying an heirloom or investment piece? Natural holds value far better.
- Want flawless clarity? Lab-grown often delivers it more affordably.
Both are legitimate, beautiful choices. The only wrong move is buying one while believing it’s the other — so always confirm what you’re getting.
Frequently Asked Questions
Are lab-grown gemstones real?
Yes. Lab-grown stones have the same chemical composition and physical properties as natural ones — a lab sapphire is real sapphire. They’re only “fake” if sold as natural without disclosure. They differ from simulants like cubic zirconia, which are different materials entirely.
Are lab-grown gemstones cheaper than natural?
Usually much cheaper, for the same visible size and quality. Lab-grown diamonds in particular have dropped sharply in price as production has scaled.
Do lab-grown gemstones hold their value?
Generally no — because they can be reproduced, they tend to depreciate, while natural stones hold value better thanks to their rarity. (This is general information, not financial advice.)
Can you tell lab-grown and natural gemstones apart?
Rarely by eye, since the materials are identical. It typically takes gemological testing, and reputable sellers disclose the origin on a lab report.
Where to Go From Here
Lab-grown and natural gemstones are both genuine — the choice comes down to your priorities: price and sourcing point toward lab-grown, while rarity, tradition, and value retention point toward natural. Decide what matters most to you, and buy from a seller who states clearly which you’re getting.
