Growing Lab Diamonds from Seeds

We’re so happy to be working with Pure Grown Diamonds. We believe in their eco-friendly product and we love their team. Over the weekend, a customer asked how exactly a diamond is grown from a seed.

Here’s what Pure Diamond has to say:

Pure Grown Diamond technology replicates the conditions necessary to grow a diamond crystal above the Earth’s surface. Grown diamonds are produced by utilizing two gem-quality diamond creation processes: High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD).

In both instances a small diamond seed is placed in a tightly-controlled environment where the rough diamond grows, atom-by-atom, layer-by-layer, recreating the natural process.

The CVD process replicates the crystallization of carbon over a diamond seed inside a vacuum chamber.

Just as in nature, carbon crystallizes on the diamond crystal seed forming a tetrahedral structure identical to one formed below the surface of the Earth.

The carbon atoms change from a gaseous state to a solid state becoming a single crystal that results in diamond formation. A rocky substance develops, waiting to reveal its gem.

Like mined diamonds, grown diamonds emerge as rough. They are polished using the same equipment and techniques; producing the same brilliance, sparkle, fire and scintillation. The only difference is origin.
