What are Lab-Grown Diamonds?
Are lab-grown diamonds real diamonds?
The answer is a very simple YES!
Lab-grown diamonds are chemically, optically and physically identical to earth-mined diamonds, but are more ethical and environmentally kind than any diamond that ever came out of the ground. They are created by replicating the Earth's natural process, crystallizing carbon in a high-tech lab environment into sparkling diamonds.
Lab-grown rough diamonds are cut, polished and graded just like their earth-mined equivalents. They have the same refractive index, dispersion and hardness, and are graded to the same standards as mined diamonds by leading independent gemological institutes.

How are lab-grown diamonds made?
Natural diamonds were formed deep beneath the Earth's surface, when carbon dioxide was exposed to extreme heat and pressure. Lab-grown diamonds use two techniques to replicate that process: High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD).
An HPHT diamond begins as a small diamond seed, which is placed in carbon and exposed to temperatures of around 1,500° C and pressure of 50 times our atmosphere. As a result, the pure carbon melts and begins to form a diamond around the starter seed.
A CVD diamond starts out as a thin slice of diamond seed, which is place in a sealed chamber and heated to about 800° C. The chamber is filled with a carbon-rich gas like methane, and other gases. The gases are ionized into plasma, breaking their molecular bonds, with the pure carbon adhering to the diamond seed and slowly crystallizing.
