ダイヤモンド市場、Q1 2026
January to March 2026
Closing out Q1 2026, active inventory across the retailers I track sat at 28,177,078 listings. Lab grown share, 63.9%. Lab grown is now the larger share of the listings I'm seeing. Retailers added 25,354,304 listings over the quarter and closed 6,122,690, a net add of 19,231,614. For diamonds carried by more than one retailer, the median price gap was 98.7%. That's the kind of gap that pays for shopping around. The five biggest contributing retailers added 35% of new listings this quarter. No single name ran away with the period. Median listing price for new arrivals, natural $1,408 and lab grown $980.
ダイヤモンド市場チャート、Q1 2026(January to March 2026)
以下の5つのチャートは、January to March 2026におけるダイヤモンド市場の動向をまとめたものです。各チャートは保存・共有可能な静止画像です。現在の価格水準、在庫の動き、lab-grownと天然の構成比、小売業者による価格の引き上げ・引き下げ、同一ダイヤモンドの販売業者間での価格差を網羅しています。

Median price movement for diamonds in each carat tier during January to March 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.

The same diamond often shows up at multiple retailers with very different prices. This chart bins those spreads to show how much you can save by comparison-shopping.
