Diamond Foundry

Diamond Foundry founded by a team of engineers from M.I.T., Stanford, and Princeton. They have developed a proprietary manufacturing technology that can deliver diamond at mining scale without the social and environmental toll of mining. Their zero-emission foundry crystallizes the very potent greenhouse gas methane into diamond, making it a sustainable alternative to mined diamonds. Diamond Foundry's man-made diamonds have a dozen of the most extreme properties of any material in the universe and are ideal for use in semiconductor solutions, electric cars, wireless technology, cloud, and AI compute. In addition to their commitment to sustainability, Diamond Foundry also acquired the values-driven digital-first jewelry startup VRAI in Los Angeles to become their direct-to-consumer channel. They have been named one of Fast Company's Most Innovative Companies and continue to revolutionize the diamond industry with their sustainable and high-quality products.
