For years, the diamond industry has chased one ideal: colourless perfection. The whiter the better, the story went. In 2026, that story is quietly being rewritten. Warm-toned coloured diamonds, champagne, cognac and soft yellow among them, are moving from niche alternative to genuine trend, and it's easy to see why.

A shift towards character over perfection

Today's clients are increasingly drawn to diamonds with individuality rather than textbook perfection. Champagne diamonds, ranging from the palest golden hues to rich honey tones, and deeper cognac diamonds, with their warm undertones of red and orange, offer a softer, more nuanced luminosity than a traditional white diamond. Where a colourless stone aims for icy brilliance, a coloured diamond offers warmth and depth, a quiet, understated luxury rather than a showpiece.

This isn't a fleeting shift either. Fancy colour diamond prices have grown at a compound annual rate of 5.7% over the past two decades, reflecting a steady, sustained rise in demand rather than a passing fashion moment.

Why they pair so beautifully with warm metals

Champagne and cognac diamonds are particularly striking set in yellow or rose gold, the warmth of the metal enhancing the diamond's own tones rather than competing with them. It's also part of a broader design movement we're seeing in 2026: softer, more sculptural ring settings with flowing, organic lines, replacing the rigid symmetry of more traditional designs. Coloured diamonds suit this aesthetic naturally, feeling considered and personal rather than mass-produced.

An accessible route into fine coloured stones

Compared to other fancy colour diamonds, such as pink or blue, champagne and cognac stones remain a comparatively accessible way to own a genuinely rare, richly coloured diamond, particularly when sourced as lab-grown stones, which we're seeing increasing demand for.
