Big, slightly tinted diamonds are suddenly the object of desire in the US — and the industry is asking why.

Buyers of 2.5-carat and up pieces are increasingly choosing stones with J color or lower, sometimes much lower on the color scale, say retailers and traders. That shift signals more than a fashion tweak: it reflects how affluent shoppers now want their diamonds to read as “natural” at a glance.

 Lab-grown gems typically come in the brightest, clearest grades, so a warmly hued, imperfect-looking stone has become a visible badge of authenticity — a deliberate antique vibe in a polished world where synthetics dominate. No surprise: The Knot reports that 61% of U.S. couples now pick lab-grown rings.

A report explores who’s buying these larger, lower-color stones, how cultural moments and celebrities — think Taylor Swift — helped fuel the taste for them, and why antique cuts seem particularly suited to carrying color. The piece also ties this appetite to broader marketing narratives, including De Beers’ push for so-called “Desert diamonds.”

It’s not all doom and gloom for mined diamonds. Larger sizes — especially 2 carats and above and long fancy shapes — have held up better than smaller goods over the past year. The report isolates this rising niche and asks the key question: can these warm-toned showstoppers withstand the continued rise of lab-grown competition?
