Lab Created Gemstones vs Natural: A Jeweller’s Guide

When customers ask us about lab-created gemstones vs natural stones, we always start with the same reassuring truth: both are real gems. The core difference isn’t about authenticity—it’s about origin and the journey each stone takes before it reaches your wrist or ears.

This guide is designed for jewelry buyers, crystal enthusiasts, and anyone interested in understanding the differences between lab-created gemstones and natural stones. We’ll compare their formation, chemical and physical properties, rarity, value, clarity, price, ethical and environmental factors, resale value, and typical uses. Understanding these differences matters for ethical, financial, and personal reasons—whether you’re seeking a meaningful birthstone, making an investment, or looking for an eco-friendly and affordable option.

At Fierce Lynx Designs, we’ve chosen to work primarily with natural gemstones for our handmade jewellery, crafted right here in New Brunswick, Canada. But we know our customers are curious about how these two types compare, especially when browsing mainstream jewellery brands alongside our artisan pieces.

Lab Created vs Natural Gemstones: Quick Answer

Here’s the straightforward comparison you’re looking for:

• Origin: Natural stones form deep within the earth over millions of years; lab-grown stones are created in controlled environment facilities over weeks or months.

• Price: Lab-created gems typically cost 20–70% less than their natural counterparts of similar appearance.

• Appearance: To the naked eye, both can look virtually identical—gemologists use magnification and specialized tools to tell them apart.

• Symbolism: Many people who value crystal healing, birthstone meaning, and earth energy prefer natural gemstones for their connection to nature.

Consider a natural amethyst bracelet versus a lab-created sapphire ring from a big-box retailer. Both feature genuine gemstones with the same chemical composition as their earth-mined equivalents. The difference? That amethyst spent millions of years forming in Brazilian volcanic rock, carrying inclusions and colour variations that make it one-of-a-kind. The lab sapphire grew in a matter of weeks, emerging with fewer inclusions and a more uniform colour.

Neither choice is wrong. But at Fierce Lynx Designs, we’re drawn to natural stones for their character, history, and the subtle energy our crystal-loving customers value.

What Are Natural Gemstones?

Natural gemstones are minerals that have been cut and polished to be used in jewelry or other decorative objects. They are minerals—or in some cases, organic materials like amber and pearl—that form within the earth and are then mined, cut, and polished for use in jewellery. They represent millions of years of geological process, shaped by extreme heat, pressure, and time in ways no laboratory can fully replicate.

The world’s most celebrated natural gems come from specific regions known for their geological conditions. Brazilian amethyst forms in volcanic cavities. Sri Lankan sapphires emerge from ancient metamorphic rocks. Colombian emeralds crystallize in hydrothermal veins. Canadian ammolite comes from fossilized ammonite shells in Alberta. Each origin contributes distinct characteristics that collectors and gemologists recognize.

Natural stones usually contain inclusions, colour zoning, and minor surface irregularities that make each bead or cabochon unique. These aren’t flaws—they’re fingerprints of authenticity. In emeralds, the French term “jardin” (garden) describes the mossy inclusions that prove natural origin. In turquoise, the matrix patterns of host rock create designs no two stones share.

What makes natural gems valuable:

• Rarity and limited supply from finite geological deposits

• Origin stories (Burmese rubies, Kashmir sapphires) that command premium prices

• Increasing scarcity as accessible deposits diminish worldwide

• Unique characteristics impossible to duplicate exactly

At Fierce Lynx Designs, we hand-select natural gemstone beads—labradorite with its mysterious flash, moonstone with gentle adularescence, rose quartz in soft pink tones—for our bracelets and earrings. We choose stones for both aesthetic appeal and the metaphysical associations our customers seek.

Note that buyers interested in crystal healing, birthstones, and earth energy typically prefer natural gemstones. There’s something meaningful about wearing a stone that formed before humans walked the planet.

What Are Lab-Created Gemstones?

Lab-created gemstones are man-made crystals grown in laboratories using technologies that reproduce the chemical composition and crystal structure of natural stones. Lab-created gemstones have the same chemical composition, crystal structure, and physical properties as natural gemstones. When gemologists examine a lab-created sapphire under magnification, they find the same aluminum oxide composition, the same crystal growth patterns, and the same optical properties as a sapphire mined in Sri Lanka.

Important terminology to understand:

• Lab-created, lab-grown, or synthetic: Chemically identical to natural stones; these are genuine gemstones grown in a controlled environment.

• Simulated stones or imitations: Different materials designed to mimic the appearance of gems (like cubic zirconia imitating diamonds or glass posing as opal).

The distinction matters. A synthetic ruby is a real ruby. A glass “ruby” is costume jewellery.

Lab-grown diamonds surged in popularity around 2015–2020, particularly in the engagement ring market. But lab-grown stones have existed far longer—synthetic sapphires have been manufactured since the early 1900s, initially for industrial use and watch crystals before entering the jewellery industry.

Typical visual traits of lab gems include high clarity, strong saturated colours, and fewer inclusions compared to many natural stones at the same price point. This uniformity appeals to shoppers seeking flawless-looking stones without premium natural gem pricing.

Why some shoppers deliberately choose lab-created:

• Affordability—access to larger carat weights and a more affordable option overall

• Vivid, saturated colours are achieved consistently

• Ethical gemstones free from mining-related concerns

• Modern appeal for those less attached to traditional symbolism

Fierce Lynx Designs does not currently use lab-grown stones in our handmade pieces. Our customers often ask about the differences when comparing our natural gemstone bracelets to mass-market brands offering lab-created alternatives—which is exactly why we’ve written this guide.

Key Differences: Lab-Created Gemstones vs Natural

Chemically, lab-created gemstones and natural gems can be identical. A lab-grown emerald and a Colombian emerald share the same beryl composition, the same crystal structure, and the same properties that define the gem. Yet origin, rarity, and symbolism create real differences in price, emotional value, and long-term worth.

Summary Comparison Table: Lab Created Gemstones vs Natural

• Formation Time

  • Lab-created: Produced in controlled laboratory environments, taking a minimum of a few weeks to a maximum of 12 months to grow.

  • Natural: Formed deep within the earth over millions of years.

• Chemical/Physical Equivalence

  • Lab-created gemstones have the same chemical composition, crystal structure, and physical properties as natural gemstones.

  • Natural gemstones are rarer and hold higher value and investment potential than lab-created gemstones.

  • Lab-created gemstones are less scarce, contributing to their affordability.

• Clarity/Inclusions

  • Lab-grown stones tend to contain fewer inclusions, resulting in higher clarity and more consistent colour.

  • Natural gemstones may contain inclusions or slight variations in colour, which are often considered part of their charm.

• Price Difference

  • Lab-created gemstones typically cost 20–70% less than natural stones of similar visible quality.

• Environmental/Ethical Factors

  • Lab-grown gemstones are considered more sustainable and ethical, as they do not require mining, have a smaller environmental footprint, and are conflict-free.

  • The environmental impact of mining natural gemstones includes deforestation, soil erosion, habitat destruction, and potential labour concerns.

• Resale Value

  • Natural gemstones generally retain or appreciate in value, especially rare varieties.

  • Lab-grown gemstones generally have a lower resale value.

• Typical Uses

  • Lab-created: Popular for large, flawless center stones in engagement rings, statement pendants, and fashion jewelry where size and clarity matter.

  • Natural: Preferred for one-of-a-kind artisanal designs, energy-focused jewelry, and investment pieces.

Key Differences in Detail:

• Origin & formation time:

  • Natural stones form over millions of years deep within the earth under extreme conditions.

  • Lab gemstones grow in weeks to months using high pressure high temperature methods or chemical vapour deposition technology.

• Chemical/Physical Equivalence:

  • Both lab-created and natural gemstones are virtually identical in terms of chemical composition, crystal structure, and optical properties.

• Rarity and Value:

  • Natural gemstones are rarer and hold higher value and investment potential.

  • Lab-created gemstones are less scarce and more affordable.

• Clarity/Inclusions:

  • Lab-grown stones tend to have higher clarity and fewer inclusions.

  • Natural stones display varied inclusions and colour characteristics unique to each stone.

• Price:

  • Lab-grown options typically cost 20–70% less than natural counterparts of comparable visual quality.

  • Natural gem prices fluctuate based on origin, colour, clarity, and rarity.

• Environmental/Ethical Factors:

  • Lab-grown stones are considered more sustainable and ethical, with a smaller environmental footprint and no mining or conflict concerns.

  • Natural gemstone mining can cause environmental and social issues.

• Resale Value:

  • Fine natural gems can retain or appreciate in value as collectibles.

  • Lab-grown stones generally carry lower resale value.

• Typical Uses:

  • Lab stones work well for large, bright center stones in engagement rings and statement pendants.

  • Natural stones are ideal for one-of-a-kind artisanal designs and energy-focused bracelets.

A practical example: A 6mm natural amethyst bead for a Fierce Lynx bracelet might cost a few dollars and display the purple colour variations, potential clarity characteristics, and geological history that make each piece distinct. A hypothetical lab-created ruby of similar size would offer intense, uniform red at comparable or lower cost—but without the millions-of-years formation story.

Practical implications for jewellery:

• Lab stones work well for large, bright centre stones in engagement rings and statement pendants, where size and clarity matter most.

• Natural stones are ideal for one-of-a-kind artisanal designs and energy-focused bracelets, such as those we create at Fierce Lynx Designs.

One more consideration: fine natural gems can retain or appreciate in value as collectibles, particularly rare varieties such as untreated Burmese rubies or Kashmir sapphires. Lab-grown stones generally carry lower resale value because production can scale to meet demand—the same process that makes them affordable also limits investment potential.

How Lab-Created Gemstones Are Made

Labs mimic the Earth’s pressure, temperature, and chemical conditions using different technologies depending on the stone type. The goal is identical: provide the right environment for crystal growth to occur, just faster than nature manages.

The process typically starts with a seed crystal—a tiny fragment of the gem material—placed in a chamber with the correct mineral mix. Technicians adjust heat and pressure to encourage crystal growth layer by layer over weeks or months. When the solution cools or conditions stabilize, the result is a rough crystal ready for cutting.

Modern lab-grown diamonds commonly use two methods:

• HPHT (High Pressure High Temperature): Replicates the extreme conditions found deep in the Earth’s mantle, subjecting carbon to around 1,500°C and immense pressure. This melt process forces carbon atoms to arrange layer by layer around a seed, creating a genuine diamond crystal.

• CVD (Chemical Vapour Deposition): Builds diamond layers from carbon-rich gas in a vacuum chamber. This method requires less energy than HPHT and allows precise control over the finished stone’s characteristics.

Traditional coloured-stone methods include:

• Flame fusion: First commercialized in 1902, this technique melts powdered ingredients with a high-temperature flame, allowing crystals to form as material drips onto a rotating pedestal. Common for lab-grown rubies and sapphires.

• Flux growth and hydrothermal growth: The flux method dissolves gem ingredients in a molten flux material; crystals form slowly as conditions stabilize. Hydrothermal growth uses water-based solutions under pressure, mimicking how many natural stones form. Both produce emeralds and other gems with fewer fractures than flame fusion.

• Crystal pulling: Used for some gem varieties, this process involves slowly withdrawing a seed crystal from a melt, allowing material to crystallize onto it at higher temperatures.

These lab-grown crystals are then cut into faceted stones or polished into cabochons for engagement rings, fashion pieces, and mass-produced jewellery lines sold by major retailers worldwide.

While Fierce Lynx Designs focuses on natural beads and cabochons, understanding these lab processes helps our customers compare what they see in big-box stores with our handmade natural gemstone pieces. Knowledge is power when shopping for gemstones.

Lab-Grown vs Simulated Gemstones

This distinction trips up many shoppers, so let’s be crystal clear:

• Lab-grown: Same chemistry and crystal structure as natural gems. A lab sapphire is a real sapphire, just born in a lab rather than mined from the earth.

• Simulated/imitations: Different materials that only look similar. These are not the same as genuine gems at all—they’re designed to fool the eye, not match the stone’s true properties.

Common examples:

• Cubic zirconia (CZ) became a popular diamond simulant in fashion jewellery starting in the 1970s. It’s zirconium dioxide, not carbon, and lacks diamond’s hardness and optical properties.

• Coloured glass or resin is sold as “crystal” in low-cost bracelets and costume pieces. These scratch easily and have no gemological value.

Durability matters here. Lab-grown gems share the same hardness as their natural counterparts—a lab-created ruby rates 9 on the Mohs scale, just like a mined ruby. Simulants often scratch more easily and won’t survive years of wear the same way real stones do.

Tips for shoppers:

• Check product descriptions for words like “glass,” “resin,” “CZ,” or “crystal” without a specific gem name—these often indicate simulants.

• Ask sellers directly whether stones are natural, lab-grown, or simulated, especially when shopping online, where photos can be deceiving.

• If a deal seems too good to be true (a “sapphire” ring for $15), it’s likely simulated.

At Fierce Lynx Designs, we use genuine natural gemstones and clearly note man-made materials like Czech glass beads or metal accents where used. Transparency keeps expectations realistic and builds trust with our customers.

Appearance, Durability, and Everyday Wear

Most people cannot tell natural from lab-grown at a glance. Even jewellers often need magnification and specialized testing equipment to identify the origin with certainty. To the naked eye, a well-cut lab-created gem sparkles just as brilliantly as its natural equivalent.

Appearance differences:

• Natural stones display inclusions, colour banding, and subtle imperfections that prove their geological journey. Think of the “jardin” (garden) in emeralds—those mossy internal features that signal authenticity—or the natural speckles in genuine turquoise.

• Lab-grown gems typically exhibit cleaner, more saturated colours and more uniform characteristics. This appeals to buyers seeking that “perfect” look, especially in faceted stones for rings and pendants.

Durability considerations:

• Both natural and lab-grown versions of the same gem share identical hardness. Lab-grown corundum (the mineral family including sapphires and rubies) rates 9 on the Mohs scale—exactly like mined gems. Lab-grown diamonds match natural diamonds at a perfect 10.

• However, natural stones with many inclusions or fractures may be more fragile in practice. Some lab-grown versions can actually prove more robust due to fewer internal flaws, though this varies by individual stone.

Everyday wear recommendations:

• For daily rings, choose harder stones —sapphires, rubies, spinels, or diamonds (natural or lab-grown) —that handle constant wear well. See our detailed guide to the best gemstones for everyday wear for more options and care tips.

• Softer natural stones like fluorite, selenite, or opal suit earrings, pendants, or occasional-wear bracelets where they face less abrasion.

• Many gemstones in the quartz family (amethyst, citrine, rose quartz) offer good durability for regular bracelet wear.

At Fierce Lynx Designs, we design natural gemstone bracelets and earrings intended for regular wear. We provide care tips with every purchase: gently clean with mild soap and water, avoid harsh chemicals, and remove pieces before sports or heavy work.

Practical care pointers for any gemstone jewellery:

• Store pieces separately to prevent scratching.

• Remove before swimming (chlorine damages many stones and metals).

• Clean periodically with a soft cloth.

• Have settings checked annually if you wear pieces daily.

Price, Ethics, and Sustainability

Both lab-grown and natural stones can be part of an ethical jewellery collection, but they raise different questions about mining impact, energy use, and long-term value. Understanding these factors helps you make choices aligned with your values.

Price realities:

• Lab-grown gems typically cost 20–70% less than natural stones of similar visible quality. A 1-carat lab-grown diamond might run 30–50% below a comparable mined diamond.

• Natural gemstone prices vary dramatically based on origin, colour, clarity, and rarity. Common stones like quartz-family gems remain affordable, while fine natural rubies or alexandrite command prices that reflect genuine scarcity.

• Lower resale value affects lab-created stones more significantly. Because production can scale up, lab gems don’t appreciate the same way rare natural specimens do. Many lab-grown diamonds retain approximately 50% of their purchase price on resale, compared with natural diamonds, which may retain more value.

Ethics and environmental considerations:

Traditional mining raises legitimate concerns:

• Habitat loss and deforestation from open-pit operations.

• Water contamination from processing chemicals.

• Soil erosion and ecosystem disruption.

• Human rights issues in some regions, including unsafe labour conditions and conflict financing (the “blood diamond” problem that drove Kimberley Process certification).

Lab-grown stones avoid large-scale digging and associated land disruption. They’re universally conflict-free. However, HPHT and CVD processes require significant energy, and the carbon footprint depends heavily on whether facilities are powered by coal, natural gas, or renewable energy. Labs powered by hydroelectric or solar energy offer more environmentally friendly production than those relying on fossil fuels.

Fierce Lynx Designs’ approach:

• We commit to using responsibly sourced natural gemstones wherever possible, prioritizing reputable suppliers that provide transparency into their origins.

• Our ethical handmade stone jewelry collections, created in New Brunswick, Canada, emphasize small-batch production and durable designs that reduce waste compared to fast-fashion jewellery.

• We believe longevity matters—pieces designed to last decades create less environmental impact than disposable accessories replaced yearly.

Guidance for conscious shoppers:

• Ask any jeweller (including us) about sourcing, country of origin, and treatments applied to stones.

• Consider whether you’d rather support small-scale mining communities or laboratory facilities.

• Choose pieces you’ll wear and love for years; longevity is perhaps the most sustainable choice, regardless of stone origin.

• Remember that “natural” doesn’t automatically mean “ethical,” and “lab-grown” doesn’t automatically mean “environmentally friendly”—details matter.

Which Is Better for You: Lab-Created or Natural Gemstones?

There is no universal “better.” The right choice depends on what matters most to you—your values, your budget, and how you plan to wear and experience the piece.

Consider which profile resonates with you:

The meaning-seeker or crystal healer gravitates toward natural stones, drawn by their connection to the earth and millions of years of formation. For this person, wearing amethyst means wearing something that crystallized in ancient volcanic rock, not in a lab. The metaphysical associations, birthstone traditions, and “earth energy” of natural gems hold genuine significance.

The budget-conscious stylist wants impact without the investment. Lab-grown options offer larger carat weights, vivid colours, and eye-clean clarity at accessible prices. A lab-created sapphire engagement ring delivers stunning blue brilliance at a fraction of the natural cost—perfect for someone who prioritizes visual wow over geological provenance.

The eco-aware buyer weighs options carefully. They might choose small-batch, natural, handcrafted jewellery (like our pieces at Fierce Lynx) that supports artisan craft and uses responsibly sourced stones. Or they might opt for lab-grown from facilities powered by renewable energy. Either path can align with environmental values—the key is researching specific brands rather than assuming one category is automatically “greener.”

The collector invests in rare natural gems for long-term value. Fine untreated Burmese rubies, Colombian emeralds with exceptional colour, or natural alexandrite with strong colour change are tangible assets that may appreciate in value. Lab-grown stones, while beautiful, don’t offer this investment potential.

When natural might be best for you:

• Spiritual or crystal healing practices where the earth's origin matters

• Birthstone gifts where the “from the earth” story adds meaning

• One-of-a-kind artisan pieces where each stone’s unique character shines

• Long-term collecting or investment purposes

• Supporting traditional gemstone communities and small-scale mining

When lab-created might be best for you:

• Wanting a large, flawless centre stone for an engagement ring without mined diamond pricing

• Seeking highly saturated coloured stones at modest budget

• Prioritizing guaranteed conflict-free origin above all else

• Fashion pieces where visual impact matters more than provenance

• Stones that will be reset or replaced as styles change
