Great Lakes Crystal Technologies (GLCT) launched in 2019 to become the leading domestic manufacturer of high-performance diamond for high-tech applications in quantum technology, electronics, optics, and high-energy particle detection. GLCT’s technical advantage derives from patented technology developed over 25 years at Michigan State University. GLCT’s R&D facility is fully operational; its prototype manufacturing line is under construction; and it is planning to create an advanced diamond materials and applications center in the Midwest to supply high-performance diamond to US Government agencies, universities, and the commercial sector while creating hundreds of high-tech jobs in materials manufacturing & applications in the Midwest.
