Prices of fancy-color diamonds declined modestly by 0.3% in Q1 compared to the previous quarter, as cautious consumer sentiment persists in light of looming U.S. tariffs, according to the Fancy Color Research Foundation (FCRF). Pink diamonds saw the smallest dip at 0.1%, with larger stones in the fancy-vivid category performing strongly—10-carat stones rose by 3%, while 5-carat stones were up 1.1%. However, 1.5-carat fancy-vivid-pink diamonds recorded a 2.3% drop, ranking among the quarter’s biggest losers.

Blue fancy-color diamond prices edged down 0.5%, reflecting a stable market trend, while yellow diamonds fell 0.7%. The most significant drop came from the 3-carat fancy-intense yellow, which declined 3%.

Despite short-term fluctuations, the long-term trend remains positive: since 2005, pink diamond prices have soared 394%, blues have risen 242%, and yellows have gained 49%.

“While global trade anxieties — particularly around renewed US tariff proposals — have undoubtedly created caution across luxury sectors, the fancy-color diamond market remained impressively composed,” said FCRF CEO Roy Safit. “In fact, given the sharp rhetoric around import duties and reshoring, many expected a more dramatic correction. Instead, the data shows a contained, strategic repositioning. It speaks to the market’s growing maturity and the defensive appeal of vivid-color diamonds.”
