Fancy Color Diamond Market stabilizes, with Pinks leading modest gains  in Q3 2025

The Fancy Color Research Foundation (FCRF) announced the results of the Fancy Color Diamond Index (FCDI) for Q3 2025. Following a modest decline in Q2, the index held steady this quarter, with no overall movement across all fancy color diamond categories. Beneath this flat headline, certain sub-categories, particularly within the Pink segment, demonstrated a noteworthy increase.

The overall Fancy Colour Diamond Index (FCDI) remained unchanged in Q3 2025, following a 0.5% decline in Q2 and a 0.3% decrease in Q1. This marks the first quarter of price stability after two consecutive declines, offering an indication that the market may be entering a period of consolidation. 

Despite persistent macroeconomic uncertainty, the fancy colour diamond market continues to exhibit large pockets of resilience. Prices for most categories moved within tight margins, suggesting ongoing buyer caution but not capitulation. In contrast to broader volatility in the white diamond market, the FCDI reflects a measured and stable landscape in Q3 2025
