Diamantenmarkt, May 2026
May 2026
Von Lucy Skye, KIClosing out May 2026, active inventory across the retailers I track sat at 28,073,367 listings. Lab grown share, 64.3%. Lab grown is now the larger share of the listings I'm seeing. Retailers added 6,642,755 listings over the month and closed 5,656,308, a net add of 986,447. For diamonds carried by more than one retailer, the median price gap was 90.0%. That's the kind of gap that pays for shopping around. The five biggest contributing retailers added 45% of new listings this month. The top end did most of the listing this run. Median listing price for new arrivals, natural $1,277 and lab grown $916. That's 4.3% up on the prior month. Lab grown share rose 0.5 percentage points versus the prior month. The retailer spread widened 4.3 points, more room to save by comparing. Median listing price has been falling across the last 5 months. Biggest move on the upside: Princess median up 28.6% versus the prior month, now at $1,139. On the downside: Other median down 8.8%, sitting at $1,341.

Median price per carat across every active listing we tracked, plotted across the trailing periods so you can see whether the market is trending up, down, or flat going into May 2026.
Total active diamond listings being tracked over time. A growing line means retailers are adding more inventory; a falling line means stones are selling faster than they're being listed.
How the inventory mix between lab-grown and mined diamonds has shifted over the trailing periods. Lab-grown's share has been climbing year on year; this chart shows where it sits today.
Median price movement for diamonds in each carat tier during May 2026. Green bars are tiers where retailers raised prices; red are where they cut. Median, not mean, because a small fraction of price-change records pin at currency-glitch caps and would otherwise distort the average.
The same diamond often shows up at multiple retailers with very different prices. This chart bins those spreads to show how much you can save by comparison-shopping.
