What Are Lab-Grown Diamonds?
Lab-grown diamonds are genuine diamonds created in a controlled laboratory environment rather than being mined from the earth.
Are They "Real" Diamonds ?
Yes. To be clear, a lab-grown diamond is not a cubic zirconia (CZ) or a moissanite, which are "simulants" made of different materials.
The Federal Trade Commission (FTC) defines a diamond as pure carbon crystallized in the isometric system. Because lab diamonds meet this definition, they are classified as real diamonds. Even professional gemologists usually cannot tell them apart without specialized equipment that detects minute growth patterns or trace elements.
Do these diamonds come with certification?
Yes. Every lab-grown diamond we offer is independently graded and certified by world-renowned gemological institutions such as IGI (International Gemological Institute) and SGL (Solitaire Gemological Laboratories).
Why are lab-grown diamonds more affordable than mined ones?
Lab-grown diamonds typically retail at a 70% to 90% discount compared to mined diamonds of the same quality. While they are priced using the same criteria—Cut, Color, Clarity, and Carat—the streamlined supply chain and efficient technology used to create them allow for a much more accessible price point.
Will the diamond lose its luster or change color over time?
Not at all. Because they share the same physical properties as mined diamonds, lab-grown stones are incredibly durable. They will never fade, become cloudy, or lose their signature sparkle. Their brilliance is permanent.
How is the quality of a lab-grown diamond measured?
Just like stones extracted from the earth, lab-grown diamonds are evaluated using the universal 4Cs:
- Cut: The precision of the facets.
- Color: The presence or absence of tint
- Clarity: The purity and lack of internal inclusions.
- Carat: The physical weight of the diamond.
How They Are Created
Scientists use two primary methods to replicate the extreme conditions found deep within the Earth's mantle:
1. High Pressure High Temperature (HPHT)
This method mimics the natural formation process. A small "diamond seed" is placed into pure carbon and subjected to intense pressure (about 1.5 million pounds per square inch) and temperatures above 1,500°C. The carbon melts and begins to form a diamond crystal around the seed.
2. Chemical Vapor Deposition (CVD)
This is a more modern approach. A diamond seed is placed in a vacuum chamber filled with carbon-rich gas (like methane). The gas is ionized into plasma using microwaves or lasers, breaking the molecular bonds. The carbon then "rains" down and adheres to the seed, growing the diamond layer by layer.
Lab Grown vs. Natural diamond
| Feature | Natural Diamond | Lab-Grown Diamond |
|---|---|---|
| Composition | Pure Carbon | Pure Carbon |
| Time to Form | Billions of years | 2 to 12 weeks |
| Cost | High (rarity-based) | Generally 60–80% less expensive |
