سوق الألماس، Q1 2026

Lab-grown diamonds now account for 65% of active inventory across the retailers I track. That's the headline from Q1 2026, and it sets the baseline for everything that follows. Of the 25.4 million new listings that appeared this quarter, roughly 17 million were lab-grown against 8.3 million naturals. The market has tilted, and it hasn't been subtle about it.

This is CaratHunter's first quarterly snapshot, so there's no prior period to compare against. What we can do is lay down the numbers as they stand. Total active inventory sits at 27.7 million diamonds, valued at just under $99.6 billion. Median price across everything: $1,105. Median carat weight: 1.34ct. That carat figure skews higher than you might expect, and it reflects the lab-grown effect. Growers are pushing bigger stones into the market at prices that make them accessible. A lab-grown diamond's median price per carat is $608, against $2,444 for naturals. That's roughly a four to one ratio, and it explains why buyers are trading up in size.

The spread story deserves attention. Nearly 49% of diamonds appear at more than one retailer, and for those stones, the median price spread is 93.5%. That means the same diamond, same certificate, can cost nearly double depending on where you find it. For buyers, this is the single most actionable number in this snapshot. Shopping around isn't optional; it's the difference between a fair deal and an expensive mistake.

Rounds still dominate new supply with 10.4 million listings this quarter, but their median price of $978 sits well below the market median. Ovals came in second at 4 million new listings and a median of $1,132, continuing their run as the preferred fancy shape. Cushions carried the highest median among popular shapes at $1,528, which tells you something about the natural share in that cut. Emerald cuts showed strong volume too (2.1 million new) and they dominated the extreme end of the market: the largest stones tracked this quarter were all emerald cut lab-growns north of 60 carats, while the priciest listings were natural emeralds and ovals in the tens of millions. Retailer concentration was moderate. The top five names accounted for about 35% of new listings, meaning the rest of the market is genuinely fragmented.

Turnover ran healthy. About 6.5 million stones went off market during the quarter against 25.4 million new arrivals, so inventory is building. That net accumulation will be worth watching: if supply keeps outpacing removals at this pace, pricing pressure on lab-grown stones in particular could intensify. Naturals held firmer in both price and turnover ratio, with roughly one removal for every 3.5 new listings compared to one in 4.1 for lab-grown.

Going into Q2, I'll be watching three things. Whether that 93.5% spread narrows as more aggregators enter the market. Whether lab-grown share pushes past the two thirds mark. And whether natural diamond prices hold their floor or start to soften under the weight of all that lab-grown volume sitting alongside them. This quarter gives us the map. The next one will show us which direction the market is walking.
