A 35% surge in new listings defined week 21. Over 1.53 million stones entered the market, up from 1.14 million the prior week, while only 310,000 left. That imbalance pushed active inventory to 28.2 m…

Nearly 1.5 million diamonds left the market in week 18, an 88% surge in removals compared to the prior week. That's the sharpest clearance I've tracked in recent weeks, and it drove active inventory d…

Listing activity fell off a cliff in week 17. New listings dropped 38% to just over 1.08 million, the lowest weekly intake across the seven weeks I've tracked this cycle. Off-market removals fell even…

Stones left the market faster than they arrived in week 16. 1.87 million diamonds went off market, more than double the prior week's 834,000, while new listings fell 27% to just 1.75 million. That's t…

The most striking thing about week 15 isn't the inventory build or the price slide in isolation. It's both happening at once, with force. Active listings jumped 6.56% week on week to 27.25 million sto…

Nearly 3.9 million stones came off the market in week 14, the highest single-week off-market count across the seven weeks I've been tracking this cycle. At the same time, new listings fell to a seven-…

The number that stops me cold this week is the price-per-carat figure. $987.50, the first time the market-wide median has broken below $1,000 in this seven-week window, and down 8% from last week's $…

Off-market listings exploded this week. 1,325,050 stones left active inventory across the retailers I track, up from just 56,591 the prior week. That's not a rounding error. It's a 22x surge in a sing…

Median price per carat hit $1,136 this week, a seven-week low and down nearly 24% from the $1,493 recorded back in W04. That's not a blip. It's a sustained compression that's been running since early …

The price compression this week is the story. Median price per carat hit $1,174.51, a seven-week low and down 12.3% from last week's $1,339.77. Median transaction price fell to $1,150, also the lowest…

2.19 million new listings in a single week. That's not a typo. Week 7 saw new listings arrive at nearly four times the pace of week 6, the biggest single-week intake across the seven periods I've trac…

The number that stopped me cold this week was 813,364 off-market listings. That's not a rounding error. Week 5 saw 145,053 stones leave the market; week 6 saw that figure jump by more than 460%. Combi…

New listings dropped 25% week on week, from 752,000 to 561,760, the lowest weekly intake across the three weeks I've been tracking 2026. That alone would be notable. But pair it with off-market depart…

The round brilliant's median new-listing price dropped to $900 this week, down 41% from $1,525 in week 1. That's a striking move on the market's highest-volume shape, one that accounted for 37.6% of a…

The first week of 2026 opens with a market that is, structurally, much larger than casual observers might expect. Over 9.18 million active listings carrying a combined value of roughly $29 billion is …
