U.S. demand stays strong for large fancy-shaped diamonds ahead of Las Vegas shows

U.S. demand for 2-carat-and-larger diamonds is still doing the heavy lifting in the trade, and the stones drawing the most heat are not the round brilliants that once defined the market’s center of gravity. Rapaport’s May 14 bulletin said elongated fancy shapes remained especially steady, antique cuts were hot ahead of the Las Vegas shows, and fancy-color diamonds were seeing strong interest. Long cushions and marquises were commanding premiums, while weak princess cuts were still difficult to move.

That split matters because it tells merchants where money is turning and where inventory can linger. The strongest stones are the ones that combine size with visual spread and a distinct silhouette: elongated ovals, long cushions, marquises, and other fancies that look larger on the hand than their carat weight suggests. In a market where buyers are still willing to pay up for shape and presence, those stones are not just decorative choices; they are the items most likely to justify firmer pricing and faster turnover.

A week earlier, Rapaport had already described wholesalers as seeing steady demand for 2-carat-and-larger F-I, VS-SI diamonds, with elongated ovals and cushions hot and melee slow. That continuity is significant. It suggests the current appetite for larger fancy shapes is not a brief reaction to show-season optimism, but a pattern that has been building through the spring, with trade buyers favoring differentiated stones over generic commercial goods. In May 2026 commentary, the market was described as bifurcated, and that is exactly how it looks on the ground: premium elongated fancy shapes are outperforming ordinary merchandise, while weaker princess cuts and small melee are harder to place.

The timing sharpens the picture. JCK Las Vegas is set for May 29-June 1 at The Venetian Expo & Convention Center, and the Las Vegas Antique Jewelry and Watch Show will run May 28-31 at Wynn Las Vegas. A year ago, Rapaport said the market was solid but cautious, with 3-carat-and-larger fancy shapes strong and suppliers hoping Las Vegas would spark trading. This year’s tone is more confident. The U.S. mood heading into the shows is positive, and that confidence is rooted in a simple trade truth: scarce, well-cut, elongated stones are still where buyer attention and pricing power are concentrated.
