Short Answer
Complete Explanation
“Lab created” describes materials that are manufactured in a laboratory rather than extracted from the earth. The term most frequently applies to gemstones and diamonds, where advanced technological processes replicate the natural conditions under which crystals form. Lab-created gemstones have the same chemical composition, crystal structure, and physical properties as their natural counterparts. They are not imitations or simulants (such as cubic zirconia), but genuine crystals with identical atomic arrangements.
- Lab-Created Diamonds:
Diamond synthesis replicates high-pressure, high-temperature (HPHT) or chemical vapor deposition (CVD) conditions to grow diamond crystals. These diamonds are optically, physically, and chemically identical to mined diamonds, but can be produced in weeks rather than over billions of years. - Lab-Created Gemstones:
Methods such as flame fusion, flux growth, and hydrothermal synthesis produce rubies, sapphires, emeralds, and other colored stones. These crystals are often free from the inclusions typical of natural gems, but can be distinguished by trained gemologists using advanced testing. - Other Uses of “Lab Created”:
The term also appears in contexts such as lab-grown meat (cultured meat), lab-created synthetic polymers, and laboratory-engineered microorganisms. However, the most widespread consumer application remains gemstones and diamonds.
History / Background
The concept of creating synthetic crystals dates back to the late 19th century. In 1902, Auguste Verneuil developed the flame fusion process to produce synthetic rubies, marking the first commercially viable lab-created gemstone. Throughout the 20th century, techniques improved, and by the 1950s, General Electric succeeded in creating the first lab-created diamond using HPHT. The 21st century saw significant advances in CVD technology, enabling the production of high-quality diamonds suitable for jewelry. Initially, lab-created gems were used mainly for industrial purposes (e.g., abrasives, optics), but improved quality allowed them to enter the consumer jewelry market. The Federal Trade Commission (FTC) updated its guidelines in 2018 to recognize lab-created diamonds as genuine diamonds, further legitimizing the category.
Importance and Impact
Lab-created gemstones have substantially altered the jewelry industry, providing an alternative to mined stones that is often less expensive and more readily available. They have also introduced ethical considerations: lab-created diamonds avoid issues such as conflict diamonds (blood diamonds) and environmental destruction associated with mining. For consumers, lab-created gems offer a way to obtain high-quality stones at lower price points, while for the industry, they challenge traditional pricing models and supply chain transparency. On the scientific front, lab-created crystals are vital for research, electronics, and laser technology. The environmental impact is complex; while lab creation avoids mining, it requires significant energy input, and the carbon footprint varies by production method.
Why It Matters
For consumers today, understanding the difference between lab-created and natural stones is essential when making purchase decisions, especially in engagement rings and fine jewelry. Lab-created diamonds are generally 20–40% cheaper than their mined equivalents, but they are not considered investments because they lack the rarity premium of natural stones. Certifications (e.g., from GIA, IGI) clearly indicate origin. Additionally, lab-created options align with growing consumer demand for sustainable and ethically sourced products. Knowledge of lab creation also matters in fields like electronics, where synthetic crystals are critical components in semiconductors, lasers, and watches.
Common Misconceptions
Lab-created gemstones are fake or imitation stones.
They are chemically and physically identical to natural ones. They are not imitations like cubic zirconia; they are real crystals grown under controlled conditions.
Lab-created diamonds are less durable than natural diamonds.
They have the same hardness (10 on Mohs scale) and toughness. A lab-created diamond can cut glass and scratch natural diamonds just as easily.
Lab-created stones are perfect and therefore less valuable.
While often cleaner than natural stones, they can still have inclusions and are graded using the same 4Cs (cut, color, clarity, carat). Their lower value stems from abundance and market perception, not inferior quality.
FAQ
Are lab-created diamonds real diamonds?
Yes, lab-created diamonds are chemically and physically identical to natural diamonds. They are made of pure carbon in a diamond cubic crystal structure and exhibit the same optical and thermal properties. Both the Federal Trade Commission (FTC) and major gemological institutes classify them as diamonds, provided they are clearly disclosed as laboratory grown.
How can I tell if a diamond is lab created or natural?
Standard gemological testing (magnification, spectroscopy, fluorescence) can distinguish lab-created diamonds from natural ones. Most lab-created diamonds have inscriptions on the girdle (e.g., "LABORATORY GROWN") and come with certificates specifying their origin. Retailers are required to disclose the origin in most jurisdictions.
Do lab-created gemstones hold their value?
Lab-created gemstones typically do not retain resale value as well as natural ones because they are more abundant and lack the rarity premium of mined stones. They are generally not considered investment-grade, though they can be used in heirloom pieces. Their market value is primarily based on cut, color, clarity, and carat weight, but resale prices are significantly lower than retail.
