Our Diamonds

LEONARDO DICAPRIO - "I’m proud to invest in Diamond Foundry Inc. – cultivating real diamonds in America without the human & environmental toll of mining."


Created by Diamond Foundry in America with masterful craftsmanship, our diamonds are setting the standard for diamonds.



“[They] are real diamonds. They have the same optical, chemical, thermal, and physical features.” Matthew Hall, Director, Gemological Institute of America (GIA)

“Lab-Grown Diamonds Are Real Diamonds”, Rob Bates, Editor, JCK The Industry Authority.

“[Manmade] diamonds are diamonds.” Federal Trade Commission, August 2018

"Mined diamonds are a gift of nature whereas manmade diamonds are a gift of human wisdom.” Shanghai Diamond Exchange’s President Qiang Lin

Diamond is a special form of crystallized carbon that can form inside Earth, on other planets, and in our foundry.

Just like ice from a freezer is as real as ice from a winter street, a diamond is a diamond regardless of origin.

Each Unique

Each diamond forms in its own way, with the same one-of-a-kind inclusions and unique growth patterns.

No two diamonds of ours are alike. Each is unique to the core.

Our diamonds are each certified with their unique gemological ID.

World Positive

World Positive

Our diamonds are hot-forged aboveground without the vast environmental & social impact of mining.

We utilize solar technology to re-create the way in which diamonds form in nature.

Creating our diamonds even takes less energy than extracting them from earth via industrial mining-- and our energy used is all renewable.

We are the world’s first diamond producer certified to be 100% carbon neutral.

Masterfully Cut

Masterfully Cut

We always cut our diamonds to perfect proportions to reveal a superior, striking diamond. It is the quality of the cut that delivers the much desired brilliance of a diamond.

Our cutting studios and polishing workshops are full of artisans and craftsmen. Our diamonds are inspected more than 1,300 times from rough stone to finished ring.

Fewer than 1% of all diamonds on the market meet this high quality level.

Guaranteed Origin

Guaranteed Origin

The origin of our diamonds is guaranteed and certain -- something impossible to know with mined diamonds from Africa and Russia that pass through dozens of owners.

Our diamonds originate in America’s beautiful Pacific West.

Our diamonds never leave our control from the moment the rough diamond is grown, to the cut and polished finished gemstone.



Large diamonds are rare. Small diamonds are plenty. Whether mined or made.

Finding or creating diamonds larger than 1 carat is extremely difficult and takes a lot of investment.

Fewer than 0.1% of all diamonds worldwide are from our foundry.

No Middlemen Markups

No Middlemen Markups

Mined diamonds pass through dozens of traders and dealers and exchanges, each one adding a markup to the final price.

By giving you direct access to our foundry, we avoid the dealer markups and import taxes.

We cut for excellent quality, not for optimized weight.
