Gemesis Diamond Company

Privately-held, Gemesis is the world's principal distributor of gem-quality lab-created diamonds and jewelry. Available in the purest Type IIa colorless and rare fancy yellow colors, these diamonds possess the same exceptional cut, color and clarity, as well as identical chemical, optical and physical characteristics as high-quality mined diamonds – the only differentiator is point of origin.

Gemesis' inventory of high-quality colorless and fancy color diamonds are produced by utilizing two gem-quality diamond creation processes: High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD). As a result of these methods, Gemesis lab-created diamonds have all the beauty of their mined counterparts and offer excellent value when compared to mined diamonds with the same characteristics.
