How to Choose A Diamond: Aboveground Creation
The following is part of our How to Choose a Diamond series, written with you in mind, for an uncomplicated, digestible understanding of all things diamond-related.
We like to consider the conflict-free origin of our diamonds the fifth ‘C,’ as the diamond source is just as important as the other grading techniques. Conflict-free diamonds are defined as those that have not fueled or financed war or violence. We eliminate any uncertainty by removing the mining process from the equation, using aboveground diamonds to ensure complete traceability on the human and environmental toll of sourcing.
Our Diamond Foundry diamonds are sustainably grown in California, chemically and compositionally equal to traditionally-mined diamonds, with the same one-of-a-kind inclusions, color scales and unique growth patterns. Individually graded on the 4C’s by a certified gemologist, you can feel good wearing our diamond designs as a symbol for a more ethical and sustainable future.

The Diamond Growing Process
01: Start With A 'Seed'
Each diamond is grown from a sliver of diamond previously grown — a completely self-sustaining cycle forged by Diamond Foundry engineers here in California.
02: Sun On Earth
The diamond sliver is placed inside a plasma reactor that replicates the energy and intensity of the sun’s outer core. This multiplies the sliver’s carbon lattice, growing the diamond atom by atom through solar energy.
03: Finished By Hand
Once the rough stone has taken form, our master cutters remove its thin outer layer of carbon to expose the diamond’s unique brilliance - a form and process identical to a mined diamond.
