About the company
Single Crystal Diamond Inc., based in Whitinsville, Massachusetts, is a small business engaged in materials science research and development for federal agencies, operating exclusively as a prime contractor on small-business-set-aside and full-and-open awards in the space and advanced materials sectors.
The vendor's recent federal footprint spans three awards totaling $7.4 million in combined potential value, all held as prime: a $7.2 million purchase order from NASA Johnson Space Center (awarded December 16, 2024) to develop, demonstrate, and mature in-space production technologies for commercial low-earth orbit destinations and platforms, including design, development, and testing of ground and flight units with flight demonstrations on the International Space Station National Lab or a commercial LEO platform; a $225 thousand firm fixed-price SBIR Phase I definitive contract from the Shared Services Center (awarded September 30, 2026) on microgravity plasma-enhanced hydrogen annealing of semiconductor materials, running through March 30, 2027; and an NSF SBIR Phase I project grant (awarded October 1, 2024, completing February 28, 2025) focused on plasma-enhanced chemical vapor deposition of high-purity diamond substrates for photonic switches and radiation monitoring devices. Work is performed at the vendor's Douglas, Massachusetts location.
Customer concentration is diffuse across the three-award window — NASA Johnson Space Center anchors the dollar value at $7.2 million, while the Shared Services Center and NSF split the remaining $225 thousand and the NSF grant respectively. Two awards (combined potential value $7.4 million) reach ultimate completion within the next twenty-four months, creating recompete exposure across the vendor's current portfolio. The vendor competes under total small business set-asides and full-and-open categories; recent work centers on SBIR Phase I awards and space-qualified materials development, with NAICS classification in research and development in the physical, engineering, and life sciences. Single Crystal Diamond maintains no parent contract vehicles, IDIQs, or GWACs in the source data, and carries no subcontract footprint.
