Closing out week 29 of 2026, active inventory across the retailers I track sat at 30,668,527 listings. Lab grown share, 64.6%. Lab grown is now the larger share of the listings I'm seeing. Retailers added 1,447,829 listings over the week and closed 160,081, a net add of 1,287,748. For diamonds carried by more than one retailer, the median price gap was 77.6%. 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 $1,391 and lab grown $936. That's 0.6% up on the prior week. Lab grown share fell 0.7 percentage points versus the prior week. Biggest move on the upside: Radiant median up 10.8% versus the prior week, now at $1,629. On the downside: Trillion median down 29.1%, sitting at $760.
