KIRA Expands to 4,000 CVD Reactors to Strengthen Global Supply and Industry Partnerships


With 250,000 polished carats now produced monthly and the largest U.S. inventory of lab- grown diamonds, KIRA ensures reliability, consistency and long-term trust for customers worldwide

KIRA, the world’s largest grower of CVD lab- grown diamonds and backed by the Kiran family’s four-decade diamond legacy, announces a significant expansion of its production capacity. The move reflects the company’s expertise in diamond supply as well as the rapidly growing trust customers place in KIRA, a leading partner for lab-grown inventory. Unlike many distributors, KIRA is fully vertically integrated, producing every diamond in-house for unmatched quality, consistency and transparency.

Scaling from 2,600 to 4,000 CVD reactors, the company is currently 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 underway, it is SMETA and SEDEX certified, underscoring a commitment to ethical and sustainable practices. Supported by more than 8,000 skilled artisans, this integrated model positions KIRA as the most scalable and dependable lab-grown diamond supplier globally.

KIRA’s decision to expand stems from three key factors:

  • Heritage of Expertise – With more than 40 years of experience through the Kiran family, KIRA brings deep supply chain knowledge and operational excellence to the lab-grown category.
  • Customer Trust – Jewelers and retailers increasingly view KIRA as a long-term partner, valuing its ability to deliver consistent quality and transparency at scale.
  • Growth & Demand – As consumer interest in lab-grown diamonds continues to accelerate, KIRA is experiencing rising demand from new and existing customers, particularly for larger and specialty stones, fueling the need for expanded production.

KIRA currently serves over 4,700 partners worldwide, spanning every level of the jewelry industry – from manufacturers, designers to major retail chains and independent jewelers. In the USA, the company maintains the largest lab-grown 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.

“At KIRA, we’re not just shaping the future of lab-grown diamonds, we’re working to make that future accessible to everyone,” said Mehul Vaghani, Founder & CEO of KIRA Jewels Inc. USA. “As the industry grows, what sets us apart is our commitment to keeping a reliable, certified inventory available at scale. This expansion is more than growth – it’s about building trust, leading responsibly and ensuring the brilliance of lab-grown diamonds can be enjoyed worldwide.”

KIRA’s web portal and mobile app provide customers with advanced, easy-to-use tools for diamond search and selection. Beyond the 4Cs, the platform delivers enhanced data and insights, helping wholesalers and jewelers buy with confidence. Inventory can also be seamlessly integrated with clients’ POS systems, ensuring smooth operations and real- time updates.

Vaghani continued, “We stay agile and closely track market shifts, using insights from our diverse customer base to anticipate demand and stock accordingly,” said Vaghani. “Right now, we’re seeing strong momentum in elongated fancy shapes in the 3–6 carat range. Our goal is to grow alongside our customers and be the resource serving every segment of the industry with precision and reliability.”
