The technology for the synthesis of single crystal diamonds for jewelry developed by CVD Spark is based on the method of chemical vapor deposition (CVD). The company has created a “recipe” for the accelerated simultaneous cultivation of several gem-quality diamonds. CVD Spark technologies can significantly increase the growth rate of CVD diamonds, which means they can reduce their cost.
CVD Spark has succeeded in producing repeatable gem-quality diamonds of consistent quality at a cost price that will allow it to count on a significant share of the global synthetic gem-quality diamond market in future scaling up of the technology.
The new CVD Spark technology allows you to control the growth mode of artificial gem-quality single crystal diamonds, expanding the possibilities of their mass production with constant quality. The company is now scaling the technology for mass production.
CEO of the TechnoSpark group Oleg Lysak
The CVD method has been used for the industrial growth of diamonds since the early 2000s; it allows the synthesis of diamonds in a plasma reactor, which are identical in chemical, physical and optical characteristics to natural ones.
Since 2018, the global production of ethical laboratory-grown diamonds has been growing rapidly by more than 15% per year (in 2020 it was more than 10 million carats), and natural diamonds are decreasing (in 2018 - 150 million carats, 2019 - 140 million carats). ). Laboratory diamonds receive the same GIA, HRD, IGI certificates as natural diamonds, with a note of origin.
TechnoSpark made a decision to spin off the production of CVD gem-quality diamonds into a separate company, together with private co-investors, information about which has not yet been disclosed. The company plans to increase production capacity in 2021 to over 1000 carats per year.
CVD Spark has been developing technologies for growing jewelry and industrial diamonds using the largest CVD reactor fleet in Russia, and has also been engaged in contract manufacturing of laboratory diamonds since 2012. The company's production and laboratory are located in New Moscow (Troitsk) in the technological campus of the TechnoSpark group of companies - the most efficient technopark in Russia according to the rating of the Association of Clusters and Technosparks 2016-2019.
