Our Story

At Diamond Foundry, we are evolving diamonds to be worthy of life's pivotal moments.

We are changing the industry by applying modern-day craftsmanship to create diamonds above the ground in America.

Zero questions around origin. Zero middlemen markups. Zero carbon footprint.

Diamonds. Evolved.

 

OUR FOUNDRY


In our foundry in San Francisco, we re-create the environment in which nature forms diamond on its own.

Our founding team of M.I.T., Stanford, and Princeton engineers previously developed pioneering breakthroughs in solar power technology. They had a hunch that techniques used to harness the energy of the sun could also be used to make a better diamond, atom by atom.

We 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. We coded software to run tens of thousands of physics-based simulations. In a warehouse just south of San Francisco, we built novel plasma reactors with hundreds of individually precision-engineered parts. Then, we formed plasma as hot as the outer layer of the sun.

It is far from easy to create diamonds above the ground – most of our early experiments failed. But after years of refinery of craftsmanship, we were able to create the conditions in which nature forms diamond on its own. Our diamond growth results in each diamond being unique.

Most simply, we discovered a fourth state of matter by which 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. (We then slice off and reuse the starting material any number of times.)

We are now able to create stunning diamonds in our San Francisco foundry. Each is a unique, one-of-a-kind crystal of pristine diamond, just like mined diamonds -- but morally pure as well. Relative to brute-force industrial mining, our production is boutique and intensely based on modern-day craftsmanship; and unlike hundreds of millions of carats produced by mines, ours are 0.01% rare.

We use solar power credits to reduce our carbon footprint to zero. We guarantee the impeccable provenance of our diamonds: each is born at our foundry in California.

MASTERFULLY CUT


Each man-made diamond grows in its own unique shape.

We have our own polishing factory where rough is cut and polished into beautifully faceted gems. We offer the broadest choice of cuts because not everyone wants the standard round brilliant.

We only cut to the highest standards, without compromising on polished weight, because the quality of the cut is most important for the brilliance of a diamond.

Our master cutters are the world's best. One of our master cutters invented the Princess Cut, among other legendary contributions to the diamond industry. Our other master cutters hail from Antwerp, Belgium in a line of four generations of diamond industry families.

Finally, a GIA Gemologist grades our diamonds, and we fully warrant this grading report. That is, you obtain a certificate, not just a lab report.

Our Jewelry


 

We are setting the standard for diamonds, so what about jewelry?

As we started learning about the jewelry industry, we found it dominated by the same old rhetoric, a stale cultural bandwagon, and an uninspired take on ethics. Modern principles of human-centered design would seem to suggest that jewelry needs to start with women and the lives they lead in this day and age.

When we met Vrai & Oro and its founder Vanessa Stofenmacher, we knew this could be Tiffany & Co 2.0. Jewelry reinvented―West Coast style―using human-centered design. Engagement rings for the modern world, away from the generic designs and outdated traditions of the industry. Rings that women would want to wear every day, made the right way―and offered with full transparency and no middlemen, just like our diamonds.

We enjoy collaborating with jewelry designers around the world who share our commitment to craftsmanship and sustainability. In 2016, we started by launching a collaboration with Barneys New York, showcasing the elegance and versatility of "innovation meets beauty". Ours were the first ever aboveground diamonds featured at a luxury department store.

Our diamond jewelry is a breathtaking mix of art, science, and nature. It is meant for people who envision a future that is bright, beautiful, and full of promise.

It’s meant for people like you.
