OUR STORY

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

We stand behind three key values: quality, simplicity, and transparency.

Our diamonds are direct from our foundry in San Francisco -- not a mine in Africa or Russia via two dozen intermediate owners.

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

Our jewelry is crafted in America by designers who share our values.

Diamond Foundry
The Evolution of Diamonds

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 make diamond – most of our early experiments failed. But after years of effort, we were able to create the conditions in which nature forms diamond on its own. Diamonds in Earth forms within a few hours actually (learn more); our process is 100 times slower.

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 produce stunning diamonds in our San Francisco foundry. Each is a unique, one-of-a-kind crystal of pure diamond, just like mined diamonds -- but morally pure as well. Relative to industrial mining, our production is boutique; and unlike vast quantities of diamond extracted underground that Earth produced for free, our production is 0.001% 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 rough 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 cutter directed the American School of Diamond Cutting and developed the Hearts on Fire premium cut brand.

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 collaborate with jewelry designers who share our commitment to quality and sustainability. We don't do fashion. Everything we offer exhibits a principle of eternal quality.

We showcase a curated selection of master artisans & designers who are recognized for their impeccable style, their attention to detail, and the quality and craftsmanship of their creations.

We launched a collaboration with Barneys New York in 2016 showcasing the elegance and versatility of "innovation meets beauty".

We entered a long-term partnership with Vrai & Oro in Los Angeles to offer fine jewelry with quality and simplicity -- and without the markups. Vrai & Oro has developed an enthusiastic following for its daily-wear jewelry, and we are excited about their upcoming offerings.

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.
