Closing out week 24 of 2026, active inventory across the retailers I track sat at 31,929,437 listings. Lab grown share, 65.9%. Lab grown is now the larger share of the listings I'm seeing. Retailers added 2,530,767 listings over the week and closed 177,393, a net add of 2,353,374. For diamonds carried by more than one retailer, the median price gap was 85.3%. That's the kind of gap that pays for shopping around. The five biggest contributing retailers added 54% of new listings this week. The top end did most of the listing this run. Median listing price for new arrivals, natural $1,724 and lab grown $610. That's 6.1% up on the prior week. Lab grown share rose 0.9 percentage points versus the prior week. Biggest move on the upside: Trillion median up 26.3% versus the prior week, now at $1,107. On the downside: Heart median down 47.6%, sitting at $643.
