Diamond Foundry

Diamond Foundry is changing the industry by standing behind three key values: quality, simplicity, and transparency.

Their diamonds are grown in the USA. Zero questions around origin. Zero carbon footprint. Their diamonds compliment handcrafted jewelry by designers who share their values.

WHY DIAMOND FOUNDRY?

REAL

Diamond Foundry diamonds originate in America’s beautiful Pacific West. They never leave Diamond Foundry's control from the moment the rough diamond is grown, to the cut and polished finished gemstone. 



UNIQUE

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

No two diamonds are alike. Each is unique to the core. These diamonds are certified with their unique gemological ID.



WORLD POSITIVE

Diamond Foundry diamonds are created above-ground without the vast environmental & social impact of mining. 

Diamond Foundry utilizes solar technology to recreate the way in which diamonds are formed in nature. 

Creating Diamond Foundry diamonds take less energy than extracting them from earth via industrial mining-- and the energy used is all renewable! As an authorized Diamond Foundry partner, we are proud to work with the Diamond Foundry who is the world’s first diamond producer certified to be 100% carbon neutral.



MASTERFULLY CUT

Each diamonds is cut 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. 

These 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

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

Diamond Foundry diamonds originate in America’s beautiful Pacific West. These diamonds never leave Diamond Foundry's control from the moment the rough diamond is grown, to the cut and polished finished gemstone.


HOW ARE DIAMOND FOUNDRY DIAMONDS CREATED?

 

The Diamond Foundry technology was born from the team’s solar technology experience — acquired over a decade and hundreds of millions of dollars of investment in developing one of the most innovative solar electricity cells ever produced, for making solar energy mainstream affordable. 

Diamond Foundry started by studying the laws of nature. Diamonds are born from a fiery heat, so we set out to create a plasma of unprecedented energy density. Diamond Foundry coded software to run tens of thousands of physics-based simulations. In a warehouse just south of San Francisco, they built novel plasma reactors with hundreds of individually precision-engineered parts. Then, formed plasma as hot as the outer layer of the sun.


It turns out diamond can be created in plasma — the fourth state of matter (the other states of matter being solids, liquids, and gases in increasing energy levels). In a plasma akin to a sun on earth, atoms can attach to nature's diamond crystal lattice and grow it in size. One by one, the atoms stack on top of a thin foundation of diamond, extending the unique crystal structure of diamonds extracted from the Earth. Atom by atom, it grows into a pure, jewelry-grade diamond of gem size. (Diamond Foundry then slices off and reuses the starting material any number of times.)



This break-through process allows Diamond Foundry to create stunning diamonds in their San Francisco foundry. Each is a unique, one-of-a-kind crystal of pristine diamond, just like mined diamonds -- but truly ethical as well. Relative to brute-force industrial mining, our production is boutique and intensely based on modern-day wisdom and craftsmanship; and unlike hundreds of millions of carats produced by mines, these are much harder to produce. 

It is far from easy to create diamonds above the ground – most of the early experiments failed. But after years of refinery of craftsmanship, Diamond Foundry was able to create the conditions in which nature forms diamond on its own. This unique process for diamond growth results in each diamond being unique. 

We can easily guarantee the impeccable provenance of our diamonds: each is born at the Diamond Foundry in America.



No Mining. No Carbon Footprint. No Cartel Pricing. No Conflicts Funded. No Land Displacement. No Wildlife Displacement. No Animals Harmed. No Ground Water Polluted. No Local Communities Displaced.
