Lab Diamond
A lab-grown diamond has the same fundamental crystal structure and chemical composition as a natural diamond but is created in a controlled manufacturing environment.
Lab diamonds may be:
- Colorless.
- Yellow.
- Pink.
- Blue.
- Brown.
- Other treated or growth-related colors.
They are traditionally associated with:
- Commitment.
- Clarity.
- Strength.
- Endurance.
- Modern innovation.
Laboratory origin does not mean a diamond is an imitation. Moissanite and cubic zirconia are different materials.
Compare optical performance, cost and composition in Lab Diamond vs. Moissanite.
Lab Emerald
Lab emerald is laboratory-grown green beryl produced to imitate the composition and appearance of natural emerald.
Its color may range from:
- Light green.
- Bluish green.
- Medium green.
- Deep saturated green.
Lab emerald is traditionally associated with:
- Renewal.
- Wisdom.
- Loyalty.
- Emotional growth.
- Thoughtful relationships.
Growth features can help gemologists separate laboratory-created emerald from natural material.
Both may contain fractures or inclusions, so safe cleaning depends on the individual stone and setting.
Lab Ruby
Lab ruby is laboratory-grown red corundum.
Its red color is primarily associated with chromium, as it is in natural ruby.
It is linked symbolically with:
- Courage.
- Vitality.
- Passion.
- Confidence.
- Determination.
Lab ruby may be produced by several methods, each leaving characteristic growth patterns or inclusions.
It should be described accurately as laboratory-grown rather than mined.
Lab Sapphire
Lab sapphire is laboratory-grown corundum produced in blue and many other colors.
Available colors include:
- Blue.
- Pink.
- Yellow.
- Green.
- Purple.
- White.
- Color-changing varieties.
Its traditional associations include:
- Discipline.
- Loyalty.
- Clear judgment.
- Responsibility.
- Long-term commitment.
The lab sapphire color guide explains the symbolism commonly assigned to different shades.
The broader lab-grown vs. natural gemstones guide covers origin, disclosure and buying considerations for manufactured gems.
Labradorite
Labradorite is a feldspar known for labradorescence—flashes of blue, green, gold, orange or violet that appear as the stone moves.
Its base color is commonly:
- Gray.
- Dark gray.
- Greenish gray.
- Brownish gray.
- Nearly black.
Labradorite is traditionally associated with:
- Transformation.
- Intuition.
- Adaptability.
- Recognizing hidden strengths.
- Navigating change.
Labradorescence results from light interacting with fine internal layers in the feldspar.
Its appearance can overlap with moonstone. Compare their optical effects in Labradorite vs. Moonstone.
Lapis Lazuli
Lapis lazuli is a blue rock composed of several minerals rather than one mineral species.
It may contain:
- Blue sulfur-bearing minerals.
- White calcite.
- Metallic pyrite.
- Other minor minerals.
Modern mineral references use “lapis lazuli” primarily for the decorative rock, not one single blue mineral.
Its traditional meanings include:
- Wisdom.
- Truthful expression.
- Confidence.
- Self-awareness.
- Intellectual curiosity.
Lapis may be dyed, stabilized or imitated. The guide to real vs. fake lapis lazuli explains common warning signs.

Larimar is the blue variety of pectolite most closely associated with the Dominican Republic.
Its colors may include:
- Pale sky blue.

- Blue-green.
- White cloud-like patterns.
- Greenish areas.
Larimar is traditionally associated with:
- Calm.
- Communication.
- Emotional balance.
- Adaptability.
- Connection with the sea.
It can resemble turquoise, dyed howlite and other blue materials. Compare them in Larimar vs. Turquoise.
Protect larimar from prolonged strong light, heat, acids and hard impacts.
Larvikite
Larvikite is a coarse-grained igneous rock known for blue, silver or steel-colored flashes from feldspar.
It is not one mineral species. It is a rock composed of feldspar and darker minerals, and it has sometimes been marketed as black moonstone or blue pearl granite.
Mineral references classify larvikite as a rock type rather than a standalone mineral.
Its symbolism includes:
- Grounding.
- Self-awareness.
- Practical judgment.
- Emotional stability.
- Recognizing hidden complexity.
Polished larvikite is used in beads, cabochons, tiles and architectural stone.
Lava Stone
Lava stone is a general commercial name for porous volcanic rock, commonly basaltic in composition.
It is usually:
- Black.
- Dark gray.
- Brown.
- Highly porous.
- Lightweight compared with many dense stones.
Its traditional meanings include:
- Strength.
- Renewal.
- Grounding.
- Resilience.
- Beginning again after change.
Lava beads may absorb perfume or essential oils, but skin sensitivity and jewelry components should be considered before applying liquids.
Lazulite
Lazulite is a blue to blue-green phosphate mineral.
It may form:
- Prismatic crystals.
- Grainy masses.
- Crystals in quartz.
- Deep blue collector specimens.
Its traditional symbolism includes:
- Focus.
- Clear thinking.
- Study.
- Mental organization.
- Independent judgment.
Lazulite has a Mohs hardness around 5½ to 6 and is brittle.
It should not be confused with lazurite, the historically named blue component associated with lapis lazuli.
Lemon Quartz
Lemon quartz is pale yellow to greenish-yellow quartz.
Some material is naturally colored, while other stones are produced or enhanced through heat and irradiation treatments.
Its symbolic associations include:
- Optimism.
- Concentration.
- Confidence.
- Clear goals.
- Productive thinking.
Lemon quartz may resemble citrine or yellow topaz, but the exact color and treatment history can differ.
Its physical properties come from the wider quartz family.
Lemurian Quartz
Lemurian quartz is a trade name for quartz crystals with prominent horizontal striations or ladder-like markings on one or more faces.
It is traditionally associated with:
- Reflection.
- Personal development.
- Memory.
- Meditation.
- Recognizing recurring patterns.
The markings are natural growth features, although not every striated quartz crystal is sold under this name.
When buying, inspect the term’s use, crystal condition and seller disclosure. The guide to buying real Lemurian quartz provides additional checks.
Lepidolite
Lepidolite is a lithium-bearing mica commonly found in:
- Lilac.
- Pink.
- Purple.
- Gray.
- Silvery-white.
It may occur as flaky masses, layered crystals or inclusions within quartz and pegmatite.
Its traditional meanings include:
- Calm.
- Transition.
- Emotional balance.
- Accepting change.
- Reducing mental clutter.
Lepidolite is soft and splits easily along its mica layers.
Learn how its sheet-like structure relates to other minerals in the mica guide.
Libyan Desert Glass
Libyan desert glass is a natural silica-rich glass found in the desert region near the border of Libya and Egypt.
It is usually:
- Pale yellow.
- Golden yellow.
- Greenish yellow.

Its exact formation has been linked to an extremely high-temperature event, such as a meteorite impact or atmospheric explosion.
Its traditional symbolism includes:
- Resilience.
- Transformation.
- Confidence.
- Survival through change.
- Personal independence.
It is natural glass rather than a mineral crystal.
Limonite
Limonite is a general term for mixtures of hydrated iron oxide minerals rather than one precisely defined mineral species.
It commonly appears:
- Yellow-brown.
- Rusty orange.
- Dark brown.
- Blackish brown.
- Earthy or botryoidal.
Its symbolic meanings include:
- Persistence.
- Stability.
- Practical effort.
- Endurance.
- Working with available resources.
Limonite may stain hands, fabric or nearby specimens with yellow-brown residue.
Lithium Quartz
Lithium quartz is a commercial name for quartz containing pink, lilac, gray or purple mineral inclusions associated with lithium-bearing minerals.
Its traditional associations include:
- Emotional balance.
- Calm reflection.
- Adaptability.
- Self-compassion.
- Releasing accumulated tension.
Appearance alone cannot confirm lithium content. Seller descriptions should not be treated as laboratory analysis.
The guide to buying real lithium quartz explains how to assess claims and treatments.
Lizardite
Lizardite is a member of the serpentine mineral group.
It may appear:
- Pale green.
- Yellow-green.
- Olive green.

It can attract iron and may align with Earth’s magnetic field when allowed to move freely.
Its traditional symbolism includes:
- Direction.
- Attraction.
- Focus.
- Commitment.

The color is generally produced through irradiation followed by heat treatment.
Its traditional meanings include:
- Communication.
- Confidence.
- Clear thinking.
