What’s the Difference Between Lab-Created Diamonds & Mined Diamonds?

Lab-Created Diamonds

We get a lot of questions about the differences between lab-created diamonds and mined diamonds. If they’re grown in a lab, are they “artificial?” Are they synthetic diamonds? Let’s shine some light on the subject…

The short answer: Gemesis lab-created diamonds are just that - diamonds. Our colorless and fancy yellow man made diamonds possess the same exceptional cut, color and clarity, as well as identical chemical, optical and physical characteristics as the highest-quality mined diamonds. The only difference? Point of origin.

The Gemesis process begins when a small diamond seed is placed in a controlled environment, under high pressure and high temperature, with carbon (the atomic component of diamond). Under these controlled conditions, the diamond grows, atom-by-atom, layer-by-layer, recreating nature’s process. Like mined diamonds, lab-created diamonds emerge in the form of rough diamonds (cutting and polishing and setting come into play later in the process).

Gemesis lab-created diamonds and mined diamonds have the same hardness, specific gravity, refractive index and dispersion factor; are polished using the same equipment and techniques; and have the same brilliance, sparkle and scintillation. This chart from our Frequently Asked Questions page makes for an easy-to-understand visual reference. Gemesis.com is a great reference for information about lab-created diamonds.
