Diamond Nexus pure carbon lab-created diamonds duplicate the chemical properties of earth-mined diamonds as well as the optical and the physical properties. (Diamond Nexus simulants replicate the optical and physical properties of mined diamonds, i.e., how it looks and wears, but not the chemical properties.) Our pure carbon series replicates all three.

Pure carbon synthetic diamonds are not available in white (clear) color. We currently offer them in yellow only.

Our pure carbon synthetic diamonds are significantly more expensive than our simulants, because the process to create them is very costly. Still, they do offer those with an interest in gemstone chemistry an added dimension.
