سوق الألماس، March 2026

Over 3.66 million diamonds left the market in March, more than double February's figure and the sharpest monthly clearance I've tracked. That's a 129% jump in removals, and it didn't come from nowhere. Active inventory still grew 32% to 27.7 million stones worth a combined $99.6 billion, both record highs, but the pace of new arrivals slowed. Roughly 10.4 million listings came on, down 16% from February. The market is expanding and churning at the same time; supply is pouring in, but stock is also cycling off shelves faster than I've seen.

Prices continued their slide. The median listing price dropped to $1,107, down 4.3% from February and the lowest since I started tracking in January. Per carat, the fall is steeper: $990.71, a 16.7% decline month on month and a 33% drop since January's $1,482. Lab-grown stones are doing most of the pulling. Their median price fell nearly 9% to $900, with the per carat figure now sitting at $566. Natural diamonds held up better, dipping just 1.3% to a median of $1,586, though per carat pricing still gave back 6.2% to land at $2,355. The gap between natural and lab-grown keeps widening: naturals now carry a median roughly 4.2 times the lab-grown per carat price.

Lab-grown's share of inventory climbed to 65.4%, up more than five percentage points from February and a new high. That shift was driven by volume; lab-grown new listings rose 4% while natural new listings nearly halved, dropping 47% to 2.6 million. Natural removals also spiked 153%, suggesting either sales or inventory consolidation among retailers carrying mined stones. The median active carat weight ticked up to 1.34ct from 1.21ct, consistent with the influx of larger lab-grown stones. Among the month's largest arrivals, a 70.83ct lab-grown emerald cut listed at around $223,000 and a 55.23ct lab-grown Asscher appeared at just $21,500. These aren't engagement ring stones, but they signal how aggressively the lab-grown segment is pushing into territory that would have been unthinkable a few years ago.

Rounds still dominate, accounting for 42.7% of new listings at a median price of $912. Cushion cuts were the only mainstream shape to gain value, edging up 1.8% to a median of $1,505. On the other end, pears dropped 18.2% to $985 and Asschers fell 21.4% to $1,270. Trillions cratered 46.6%, though with only 8,301 new listings they're a niche shape where a handful of high or low priced stones can swing the median easily. The top of the market still commands serious money: a 2.03ct natural fancy radiant listed at $10.68 million, and a 31.05ct D Flawless pear at $6.24 million.

Cross-retailer overlap rose to 48.9%, meaning nearly half the diamonds visible across the retailers I track are listed by more than one seller. The median spread on those shared stones hit 93.7%, another record. That's the gap between the cheapest and most expensive listing for the same diamond. For buyers, this is the clearest signal yet that shopping around pays off. The same stone can effectively cost double depending on where you find it. A top five group of retailers accounted for 41.8% of all new listings, so concentration remains moderate, but comparing prices across the retailers I follow has never been more worthwhile.

April will tell us whether the clearance surge reflects genuine sell through or seasonal catalogue cleanup ahead of Q2. If median prices keep falling while inventory grows, the balance of power tilts further toward buyers, especially in the lab-grown segment where $900 now buys a solidly sized stone. Worth watching.
