What New Diamond Technologies does

New Diamond Technology (NDT), founded in 2014 and headquartered in Sestroretsk (Saint Petersburg), Russia, manufactures high-purity single-crystal diamonds using proprietary High Pressure High Temperature (HPHT) synthesis. The company produces nitrogen-free Type IIa crystals — including the largest HPHT-grown colorless (10.02 ct, 2015), blue (10.07 ct Fancy Deep Blue, 2016) and orange (20.22 ct Fancy Vivid Orange, 2018) lab-grown diamonds on record — and uses boron doping to make conductive Type IIb material. Operationally, NDT runs a single manufacturing facility with approximately 126 employees and operates under a private, founder-controlled ownership structure led by General Director Roman Koliadin and President Tamazi Khikhinashvili, with R&D anchored by doctors of science A. Katrusha and A. Koliadin.

NDT serves three end markets from the same production platform: (1) the jewelry market, where it sells IGI- and GCAL-certified polished diamonds in sizes 1.0–10.0 ct, colors D–H and Fancy Blue, and clarities IF–SI through direct B2B sales and booths at JCK Las Vegas, Hong Kong Jewellery & Gem Fair, Basel World, Dubai and IIJS India; (2) the industrial and scientific market, supplying single-crystal diamond plates (2.5×2.5 to 15.0×15.0 mm, IIa/IIb, nitrogen- and boron-doped up to 10 ppm) for power electronics, radiation detectors and CVD seeding, plus diamond anvils rated above 100 GPa and diamond lenses for IR/UV/visible/X-ray applications; and (3) a niche research and commemorative market, including bespoke diamonds grown from non-carbon materials such as hair, leather, wool and wood, and collaborations with MIT, Oxford, ESRF, Fraunhofer IAF, CEA, Max Planck and CNRS, including co-leadership of the Green Diamond consortium for diamond-based HVDC power electronics. All sales are quote-based, multi-year enterprise contracts processed through a dedicated sales department rather than via published pricing, and NDT is a co-founding member of the International Grown-Diamond Association (IGDA).
