Grown Diamonds
After decades of research and development, our scientists can now precisely replicate the earth's natural growing process of crystallizing carbon into brilliant, conflict-free diamonds that are chemically, optically, and physically identical to earth-mined diamonds, yet cost 30 to 40 percent less (according to the Federal Trade Commission).

Diamond Hybrid
Another stunning option for those seeking conflict-free diamonds, the Diamond Hybrid is the most realistic-looking diamond simulant available, exclusively offered at $295.00 USD per carat. It is created by placing a perfectly cut crystal core into a chamber of intense heat and pressure and infusing Lab-Grown Diamond crystals (bonding them at a molecular level) into the outer layers of the crystal core. The result is a diamond-infused simulant that has a non-precious crystal core and a non-porous solid outer layer of Lab-Grown Diamond that will never wear off or detach from the core.

Unmatched Beauty
The Diamond Hybrid averages a D to F in color, VVS1 to VS2 in clarity, and Excellent to Very Good in cut.

Exceptional Value
Priced at $295.00 USD per carat, regardless of the shape, the hybrid conflict-free diamonds are available at approximately 3% of the cost of an earth-mined diamond.

Lifetime Guarantee
The Diamond Hybrid Lifetime Guarantee covers any color change or chipping due to manufacturer defects, as seen by the naked eye.

Socially Responsible
Approximately 150 tons of earth per carat remains untouched because of customers choosing a Diamond Hybrid simulant over an earth-mined diamond.
