A Note From Our President

Blue and Pink diamonds continue to shine as the cornerstone of investment-grade assets within the fancy color diamond universe. In a year when many traditional benchmarks have shown little movement, these exceptionally rare gems have once again demonstrated their resilience and enduring appeal. Market activity has increasingly concentrated around the most coveted areas—vivid and intense Blues, and select mid‑ to large‑size Pinks—where scarcity meets sustained demand. Notably, vivid Blues in the 5–10 carat range recorded the quarter’s strongest performance, reaffirming their status as one of the most secure and value-retentive stores of wealth available today.

For discerning collectors and family offices, the message is unmistakable: this is not a passing trend, but a disciplined and maturing market that rewards selectivity and quality. While headline indices may appear steady, underlying data reveals firm to rising prices in the finest segments—2‑carat Fancy Intense and 1‑carat Fancy Vivid Pinks showing upward movement, alongside robust appreciation in large vivid Blues. In essence, capital continues to seek the clarity of true rarity. Those focused on superior Blue and Pink diamonds—vivid, intense, and appropriately sized—are not only preserving wealth, but positioning themselves where long‑term value growth remains both authentic and compelling.

Since launching its data collection efforts in 2005, the Fancy Color Research Foundation has documented long-term appreciation across all Fancy Color Diamonds, with an overall increase of 203.37%. As of Q4 2025, Yellow diamonds have risen by 47.4%, Pink diamonds by 390.9%, and Blue diamonds by 241.7%.

Notes About the Data

This data is collected independently and analyzed. It is our industry’s most comprehensive and non-biased source for diamond data. Some things to note - when you see results for Pink diamonds, this data only includes diamonds over 1 carat. This is important to know because most pink diamonds came from the Argyle Mine and the majority of Argyle diamonds weigh less than 1 carat but are worth more than *most* non-Argyle pink diamonds that are larger than 1 carat.

Also of note, “all diamonds” may not include high-value colors such as Green diamonds due to rarity. Even if these colors were included in the data, the figures would get lost in a sea of other colors that are more readily available and less valuable. Certain cuts are also not included in the survey, such as pear shapes, ovals, and emerald cuts.

FCRF Q4 2025: Fancy Color Diamond Market Sees Minimal Change in 2025, Blue Diamonds Show Momentum

The Fancy Color Research Foundation (FCRF) announced yesterday the results of the Fancy Color Diamond Index (FCDI) for Q4 2025.

The Index posted an unchanged reading this quarter, reflecting continued stability across the Fancy Color 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 Color Diamond sector continues to show resilience in specific high-saturation categories, particularly in vivid and intense blues.

The overall Fancy Color 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.  

Over the past 12 months, the Index declined by almost one percent. While pricing pressure persists, it has remained contained and largely isolated to specific segments. Compared to broader movements in the diamond industry, the Fancy Color market continues to show resilience. The limited overall movement suggests an environment shaped by caution rather than retreat.

This quarter’s marginal decline reflects the ongoing segmentation of the market. Strength remained concentrated in rarer stones with strong color saturation and larger sizes, particularly within the Blue and Pink categories. Standard Yellow diamonds continued to weigh on the index, with softness across several size ranges. As a result, the flat headline figure masks more dynamic activity below the surface.

These results suggest that demand continues to center on stones with vivid or intense color and desirable size, rather than across the broader market. The data highlights a selective environment where buyers are focused on rarity and long-term value.

The Pink diamond category recorded a small decline of 0.2% in Q4 2025, reversing the modest gain seen in the previous quarter. On a 12-month basis, the category is down 0.7%, continuing a trend of mild correction that has defined much of the year. While the overall figure suggests softness, price movements within the segment were mixed, with notable strength in a handful of vivid and intense stones.

Among the strongest performers were the 2-carat Fancy Intense Pink, which rose by 1.3%, and the 1-carat Fancy Vivid Pink, up 0.8%. Gains were also observed in several 10-carat stones across saturation levels. These results reflect ongoing interest in highly saturated stones in both mid-size and larger formats.

However, pricing remained under pressure in other parts of the category. The 1.5-carat Fancy Intense Pink decreased by 2.0%, while declines were also recorded in the 1 and 5-carat Fancy Intense Pink segments. These results point to continued selectivity among buyers, with performance closely tied to saturation level, size, and specific market preferences.

The Blue diamond category rose by roughly 0.3% in Q4 2025, marking its first quarterly increase of the year and the strongest showing among the three color segments. This follows modest declines in the first three quarters and brings the category’s 12-month change to –0.7%, underscoring its reputation for relative consistency during a year of broader market adjustment.

The quarter’s gains were driven primarily by vivid stones in larger sizes. The 8-carat Fancy Vivid Blue rose by 2.1%, with the 10-carat and 5-carat categories also posting increases of 1.4% and 1.2%, respectively. These movements reflect continued interest in top-quality stones where both color intensity and size converge to create rarity.

At the same time, softness persisted in a few parts of the category, particularly among intense stones in higher weight brackets. The 10-carat Fancy Intense Blue slightly declined by 1.3%, and similar patterns were observed in 5 and 8-carat intense stones. Nonetheless, the overall performance this quarter reinforces the Blue segment’s profile as a stable and investment-focused category within the Fancy Color market.

The Yellow diamond category presented a modest decline of about 0.2% in Q4 2025.  This follows a 0.4% decline in Q3 and brings the segment’s 12-month decrease to 1.9%, making it the most affected among the three color categories.

Despite the broader softness, several subcategories posted notable gains. The 1 and 1.5 carat Fancy Intense Yellow stones each rose by 1.1%, while the 8 carat Fancy Intense Yellow and 1.5 carat Fancy Vivid Yellow also saw moderate increases. These results point to sustained interest amid well-saturated stones in smaller and mid-range sizes.

At the same time, a number of commercial Yellow categories continued to apply downward pressure. The 3-carat Fancy Yellow declined by 2.5%, and the 5-carat Fancy Vivid Yellow declined by 2.0%. As with previous quarters, market feedback suggests that demand remains highly selective, with buyers favoring vivid and intense stones that combine rarity with preferred size and shape attributes.

Dhruval Dholakia, Head of Operations and Resources at Shree Ramkrishna Exports (SRK), observed:

“As a manufacturer active in both colorless and color diamonds, we experience daily price movement as part of the business. The unchanged levels in fancy color diamonds highlight a different discipline. This is a segment where inventory can be built deliberately, without pressure from short-term price noise.”
