Company Overview

Diamond Foundry is a producer of lab-grown diamonds for both the jewelry and technology industries. Founded in 2012 by engineers from M.I.T., Stanford, and Princeton, the company utilizes a proprietary plasma reactor technology to create high-quality, single-crystal diamonds with a zero-carbon footprint. Initially focused on providing a sustainable alternative to mined diamonds for jewelry, including through its subsidiary VRAI, the company has expanded its mission to address thermal challenges in high-power technology. It now manufactures single-crystal diamond wafers and chiplets intended to enhance the performance of AI and cloud computing chips, electric vehicle power electronics, and wireless communication technologies. The company has received significant funding from notable investors, including Fidelity and Leonardo DiCaprio.
