In March 2026, the global diamond market recorded a decline in prices across key segments. According to RapNet data, the RAPI index fell by 1.7% for 1-carat diamonds, by 1.1% for 0.3-carat stones, by 3.5% for 0.5-carat stones, and by 0.5% for 3-carat stones.

At the same time, the segment for large stones—weighing 2 carats and above—continues to demonstrate robust demand amidst limited supply, particularly within the fancy shapes category. The market remains uneven, exhibiting varying dynamics across different categories.

The geopolitical situation exerted additional pressure: trading activity in Israel and Dubai contracted following missile strikes, and several diamond tenders were postponed. This heightened uncertainty and curtailed market participant activity.
