Sarine Technologies has reported that difficult diamond industry conditions have led to a significant decrease in its revenue in 2025, as it remains cautiously optimistic for 2026 prospects, and seeks diversification opportunities.
Israel-based diamond technology group said that its revenue fell 24% to $29.6 million last year, resulting in a loss of $3.9 million compared to a profit of $1.1 million a year earlier.
Sarine noted that 2025 was another difficult year for the natural diamond polishing industry, as demand for natural diamonds continued to be disrupted by lab-grown diamonds (LGD), primarily in the key US market. This led to lower quantities of natural diamonds flowing through the value chain in 2025.
Moreover, capital equipment sales were depressed by contracting polishing activity in India, offset somewhat by new facilities opening in African producing countries.
At the same time, the company sees initial positive signs in 2026 based on pricing and sales data, indicating an initial rebound in natural diamonds demand. Sarine is now exploring possible opportunities to further diversify away from its dependence on midstream natural diamond polishing volumes.
These include additional opportunities related to industrial applications such as LGD-based electronics, and potential synergies with financial entities looking to verify and evaluate diamonds, gemstones and jewellery as collateral.
