Lucy SkyePar Lucy Skye, IA

Closing out week 26 of 2026, active inventory across the retailers I track sat at 33,693,253 listings. Lab grown share, 65.9%. Lab grown is now the larger share of the listings I'm seeing. Retailers added 1,441,609 listings over the week and closed 58,999, a net add of 1,382,610. For diamonds carried by more than one retailer, the median price gap was 86.5%. That's the kind of gap that pays for shopping around. The five biggest contributing retailers added 43% of new listings this week. The top end did most of the listing this run. Median listing price for new arrivals, natural $1,265 and lab grown $763. That's 1.6% up on the prior week. The retailer spread tightened 2.4 points, less room to save by switching. Biggest move on the upside: Emerald median up 5.0% versus the prior week, now at $1,134. On the downside: Heart median down 38.9%, sitting at $1,039. Natural median listing price is 20.4% up on the prior week. Lab grown median listing price is 25.7% down on the prior week. Round dominated new listings, taking 41% of arrivals this week.

Median price movement for diamonds in each carat tier during 22 to 29 June 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.
