Lab Diamonds
Exceptional Beauty, Exceptional Value
Lab diamonds are real diamonds. They share the exact same chemical, physical, and optical properties as natural earth-mined diamonds. The only difference is how they are created. While natural diamonds form deep within the earth over billions of years, lab diamonds are grown using advanced technology in controlled environments.
Because lab diamonds cost significantly less than natural diamonds, you can choose a larger stone or higher quality grade without stretching your budget. You get the exact same sparkle, fire, and strength. The choice comes down to what matters most to you.
What Is a Lab-Grown Diamond?
A lab diamond is made of pure carbon atoms locked in a crystal lattice structure. It is atomically identical to an earth-mined diamond.
Producers create gem-quality lab diamonds using two main techniques:
- HPHT (High Pressure High Temperature): Replicates the extreme heat and pressure conditions found deep underground.
- CVD (Chemical Vapor Deposition): Grows diamond crystals layer by layer inside a specialized vacuum chamber using carbon-rich gas.
Both methods produce authentic diamonds. Independent gemological organizations like the Gemological Institute of America (GIA) and the International Gemological Institute (IGI) grade lab diamonds using the standard 4 Cs: Cut, Color, Clarity, and Carat weight.
Lab Diamonds vs. Natural Diamonds
| Feature | Lab-Grown Diamonds | Natural Diamonds |
|---|---|---|
| Chemical Structure | Pure Carbon | Pure Carbon |
| Mohs Hardness | 10 (Maximum) | 10 (Maximum) |
| Brilliance & Fire | Identical | Identical |
| Certification | Certified by GIA, IGI | Certified by GIA, IGI |
| Origin | Modern Laboratory | Earth's Mantle |
| Price Point | 40% to 70% lower cost | Higher cost due to mining and scarcity |
Why Choose Lab Diamonds for Your Collection?
Get More Carat Weight for Your Budget
The biggest benefit of choosing a lab diamond is purchasing power. For the cost of a modest natural diamond, you can choose a larger center stone with better color (grades D to F) and exceptional clarity.
Built for Daily Wear
Lab diamonds score a 10 on the Mohs hardness scale. They are scratch-resistant and exceptionally durable, making them ideal for engagement rings, wedding bands, stud earrings, and daily jewelry.
Fine Jewelry Style Without the Worry
You can wear and enjoy fine diamond jewelry without feeling like you have to keep it locked away in a safe. Lab diamonds give you the look, weight, and feel of high-end jewelry for everyday life.

Frequently Asked Questions
Will a lab diamond pass a diamond tester?
Yes. Lab diamonds have the exact same thermal and electrical conductivity as natural diamonds, so they test as real diamonds on standard testing equipment.
Do lab diamonds cloud or change color over time?
No. Lab diamonds will never cloud, fade, or turn yellow. Their clarity and brilliance are permanent.
Are lab diamonds the same as cubic zirconia or moissanite?
No. Cubic zirconia and moissanite are diamond simulants. They look similar on the surface, but they have completely different chemical structures and physical properties. Lab diamonds are 100% real carbon diamonds.
