Our forged diamonds hail from the Diamond Foundry, a San Francisco company that re-creates the power of the Sun on Earth to grow ethically and atomically pure diamonds.

While mined diamonds generally pass through a dozen owners with an origin impossible to trace, Diamond Foundry lab created diamonds are guaranteed to come directly from their birthplace in California.
Observing that diamonds are born of a fiery heat, the Diamond Foundry team of M.I.T., Stanford, and Princeton engineers set out to build a plasma reactor that would rival the heat at the outer layer of the Sun. With this power it stacks atoms one by one onto a thin layer of natural diamond, extending its natural crystal lattice until it grows into a pure gem size diamond. The scientists then slice off the newly born diamond and reuse the starting material many times over.
Diamond Foundry diamonds are cut to the most exacting standards by artisans with three generations of experience. Their Master Cutters in California have made notable contributions to the industry — one as the inventor of the Princess Cut and the other directing the American School of Diamond Cutting.
Each diamond is graded by a GIA Gemologist according to the strictest professional standards. Via the Diamond Foundry, we certify & warrant the reported Cut, Color, Clarity, and Carats. We even guarantee 100% of your diamond’s value.
