Fast Company: This Fine Jewelry Brand Puts a (Better) Ring On it

Last year, Vanessa Stofenmacher wanted to expand her three-year-old direct-to-consumer fine jewelry brand, Vrai & Oro, to include engagement rings. But she couldn’t stand the thought of buying traditionally mined diamonds, which are often unearthed in war-torn countries and sold to fund conflicts. Here’s how she found a stone with no skeletons, and modernized the engagement-ring shopping experience along the way. ROMANCING THE STONE...

Wired UK features Diamond Foundry

This startup is growing diamonds.   For centuries, people have gone to great lengths and extraordinary costs - from the baked Namib Desert to the ice-locked Canadian tundra - to pull diamonds out of the Earth, endlessly searching for the dead volcanoes that thrust those transmuted carbon relics from the planet's core and into a special place in our imaginations. But one no longer has to go so far, or get very dirty, to find diamond. In...

Origin of Diamond Foundry

At Diamond Foundry, our mission is to cultivate the world’s most evolved diamonds. Our diamonds have incredible beauty and the highest quality, but are created without compromise.

Inc’s 25 Most Disruptive Companies of the Year Check out why Diamond Foundry made the list.

For creating a new source of diamonds that doesn’t involve environmentally destructive mining and exploitative labor practices. WHY IT’S DISRUPTIVE Diamonds aren’t really rare. They’re just hard to get to–buried deep underground, generally in parts of the world that lack strong governments. Getting them to an American jewelry store often involves destructive pit mining, slave or child labor, violent militias, and a long chain of middlem...

Pulitzer Prize-winning journalist John Markoff profiles our company in an in-depth article in the New York Times. He articulates the essence of our technology and gives context to the process by which we developed it: “The process begins with a very thin slice of natural diamond as a substrate and then increases the size of the original diamond material by adding more layers of carbon atoms… By modifying the shape of the plasma field to...

Brilliant Earth Caught in Crossfire: ‘Conflict Free’, ‘Ethical’ Marketing in a Messy Industry

When Beth Gerstein and Eric Grossberg founded Brilliant Earth out of Stanford Business School, they had their heart in a good place and their finger on a real problem: the ethics of the diamond industry. The diamond industry has a long history of talking the “ethical” talk but otherwise supporting business as usual. The Kimberley Process Certification Scheme was one of its major initiatives — in light of blood diamonds, sales would have...

The article explains not only the inspiration and investors behind our company, but also delves into the scientific process as well:  “An investor in Diamond Foundry likened the process to growing a plant.

WSJ: De Beers Tries to Counter the Threat of Cultivated Diamonds

The WSJ reports about De Beers being bedeviled by man-made diamonds. It’s a headline that the WSJ put above the FBI clearing Clinton of her emails three days before the Presidential election. The WSJ uses the language of De Beers, calling cultivated diamonds “synthetic” even though even the FTC has stated that cultivated diamonds are not accurately referred to as such. De Beers diamonds are then called “real” even though cultivate...

Observer: A Collaboration That’s Tough To Top

The Observer notes in its Style & Design section: “This is reportedly the first time a major retailer has agreed to a collaboration with a cultivated diamond company and it’s certainly going to be a tough one to top.” “Diamonds might be a girl’s best friend, but they certainly don’t have the same cheerful relationship with the environment. […] That’s why plenty of brands are placing their bets on cultivated diamonds, which are stone...

Diamond takes hours to form in Earth (not billions of years)

Some people think that Earth diamonds take billions of years to form.  But the fact is that today we know that the process of forming diamond itself can just take hours and days under the kinds of pressures available deep inside the Earth. (Of course, then diamonds can lie in the ground for any length of time.) Deep inside the Earth, there exist pressures of 5GPa and up to 350 GPa and higher.  Under those conditions, we now know diamond...

Ring Anatomy: Learn Lingo of Our Diamond Designers

Diamond designers have a language all their own. It’s not just the “sticky up-y part;” its the prongs. It’s not the “side of the ring,” but the shoulder. Shopping for a ring can be daunting, especially if you intend to customize it. To narrow in on what you want, it helps to know the lingo. Consider this the legend to your ring’s map, explained! Head The head of the ring refers to the parts that are elevated from the shank. This often ...

Diamonds: How Rare Are They?

Our own diamonds represent less than 0.001% of all diamonds on earth. Our foundry production is smaller than the number of bottles of Chateau Petrus 1971. Each diamond we produce is a piece of art with its unique signature because each diamond grows differently. No two diamonds of ours are alike. Mined diamonds are not so rare in comparison. Mining is the ultimate mass production; it occurs at a scale unlike any other human activity....
