The Fancy Colour Research Foundation (FCRF) announced today the results of the Fancy Colour Diamond Index (FCDI) for Q4 2025. The Index posted an unchanged reading this quarter, reflecting continued stability across the Fancy Colour Diamond market. While overall movement was modest, results reveal a nuanced landscape, with Blue diamonds posting a slight gain and Pink and Yellow diamonds showing mild downward adjustments.
The data points to a market that is measured and selective, with pricing influenced by stone rarity, saturation, and size. Over the trailing 12 months, the Index declined 1.0%, rounding out a year marked by restrained activity and modest corrections. While not immune to broader market pressures, the Fancy Colour Diamond sector continues to show resilience in specific high-saturation categories, particularly in vivid and intense blues.
The overall Fancy Colour Diamond Index (FCDI) remained largely unchanged in Q4 2025, following a flat reading in Q3 and earlier declines of 0.5% in Q2 and 0.3% in Q1. This marks the third consecutive quarter of stagnation, and may suggest the market has found a bottom to bounce back from.
