- Week 22, 2026
Nearly 1.9 million new listings hit the market in week 22, the highest single week count across the seven periods I've been tracking. That's a 24% jump on the prior week and 31% above the rolling aver…
- Week 21, 2026
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…
- Week 20, 2026
Only 398,586 stones came off the market this week, a 77% drop from the prior week and the lowest figure I've tracked across the last seven periods. For context, week 19 saw nearly 1.74 million removal…
- Week 19, 2026
Lab-grown supply flooded in this week. 1.15 million new lab-grown listings hit the market, up 63.6% on the prior week, and the median price per carat for those stones collapsed to $448, down a stagger…
- Week 18, 2026
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…
- Week 17, 2026
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…
- Week 16, 2026
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…
- Week 15, 2026
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…
- Week 14, 2026
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-…
- Week 13, 2026
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 $…
- Week 12, 2026
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…
- Week 11, 2026
Off-market activity collapsed this week. Only 56,591 listings left the market across all the retailers I track, down 83% from last week's 338,873 and the lowest single-week exit figure in the seven-we…
- Week 10, 2026
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 …
- Week 9, 2026
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…
- Week 8, 2026
The number that stopped me this week was 6.23 million new listings hitting the market in a single seven-day window. That's an 185% jump on last week's already-elevated count, and it pushed active inve…
- Week 7, 2026
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…
- Week 6, 2026
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…
- Week 5, 2026
The number that catches my eye first is off-market activity: only 145,053 listings came off the market in week 5, down 48% from the 279,060 we saw the week prior and the lowest single-week figure acro…
- Week 4, 2026
The quietest exit rate in four weeks is the most telling number from week 4 of 2026. Only 279,060 stones came off the market, down 35% from the prior week's 432,612 and the lowest off-market count acr…
- Week 3, 2026
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…
- Week 2, 2026
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…
- Week 1, 2026
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 …
