## About

Founded in 2013 and based in San Francisco, CA, Diamond Foundry Inc. produces lab-grown diamonds for jewelry and high-tech applications using sustainable, zero-emission technology. Co-founded by Martin Roscheisen and Jeremy Scholz, Diamon Foundry Inc. has raised a total of USD 385.23 million across 6 rounds of funding. As of 2021, the company was valued at USD 1.67 billion. The company developed five generations of plasma reactor designs using software simulations of plasma physics to develop its technology for managing a high-density plasma for diamond growth at extremely high temperatures. In December 2024, Diamond Foundry Inc. received EUR 81 million in grant funding from the European Commission. The brand sells diamonds that are of the same nature as natural jewels, but without the mining industry's exploitation and with no carbon footprint, allowing customers to buy luxury jewelry and products with a choice.
