NEW YORK – KIRA Jewels, the world’s largest grower of CVD synthetic diamonds, which is owned by the Kiran family, has announced a significant expansion of its production capacity.
The move reflects the company’s expertise in diamond supply and the trust customers place in KIRA, a leading partner for synthetic inventory, a statement from the company said.
Unlike many distributors, KIRA is fully vertically integrated, producing every diamond in-house for quality, consistency and transparency.
Scaling from 2,600 to 4,000 CVD reactors, the company is now producing 250,000 polished carats each month at its 1 million sq. ft. solar-powered facility.
Powered by 75 MW of installed solar energy, with expansion to 150 MW under way, it is SMETA and SEDEX certified, underscoring a commitment to responsible practices.
Supported by more than 8,000 skilled artisans, this integrated model positions KIRA as one of the most scalable and dependable synthetic diamond suppliers globally.
KIRA currently serves over 4,700 partners worldwide, spanning every level of the jewelry industry – from manufacturers and designers to major retail chains and independent jewelers.
In the United States, the company maintains the largest synthetic diamond inventory, including 150,000 certified stones available for next-day delivery from its New York office.
Globally, KIRA stocks more than 250,000 certified stones across all shapes, sizes and qualities to meet every market demand.
