Sarine Technologies’ sales fell last year as the lab-grown diamond market in the US grew and consumer confidence in China dipped.

Revenue dropped 25% to $29.6 million for 2025, the Israel-based supplier of diamond-grading technology reported last week. This resulted in a loss of $3.9 million compared to a profit the year earlier. The company lowered costs by moving the manufacturing and support operations to India, it added.

Reduced polishing activity in India affected sales of capital equipment, though new facilities opening in African producing countries partly offset this. The overall drop in sales stemmed from the lower demand for natural diamonds, as the lab-grown market continued to improve in the US.

Sales to India fell 24% to $14.8 million for the year, while revenue from the African market slid 10% to $4.5 million, and in the US it fell 2.5% to $4.9 million. Europe saw a 35% drop in sales to $2 million.

The company also acquired 33% of Kitov.ai in August to allow it to tackle the challenges in the diamond industry. Kitov.ai, which has developed a quality assurance and control (QA/QC) system, will help the company expand into fields beyond the diamond sector.

“The group is cautiously optimistic for 2026 as demand for natural diamonds is seemingly showing an initial rebound and new services’ revenue streams are accelerating through their wider adoption by midstream and downstream customers,” the company said. “We are also looking into potential synergies with financial entities for supporting their extension of credit to the diamond, gemstone and jewelry industries, based on actual collateral verification and valuation.”
