HaiNan Neocrystech Co., Ltd. is the exclusive distributor worldwide for SuperCrystal lab grown diamond. Neocrystech offers quantum-grade diamond products that contain deliberate and controlled levels of nitrogen-vacancy (NV) centres, including high-quality single and ensemble NV centres.

Our exclusive production features an internally dispersion of single NV centers (SNV) in a density between 10 and 300 per 10000 µm², with typical spin coherence times (T2) exceeding 300 µm and a long T2* of 1~3 µm. We support for customization in single NV density, diamond size, and preferred polished faces {100},{111} or {110}.

Our ENV diamonds contains high density NV centres varying from 500 ppb to 4 ppm, with T2 ranging from 100 to 200 µm and T2* of 0.5 µm. We offer customized diamonds with major {100},{111} or {110} in different densities up to 10 ppm.
