Independent jewelers in the United States posted another double-digit June, but the growth again came almost entirely from higher tickets rather than more transactions. Total retail sales rose 18% year over year, according to figures from the Edge Retail Academy, while unit sales across all categories came in flat and the average retail sale climbed 18%. It is the same equation the trade has balanced all year, and June did nothing to change it.

Natural diamonds gain on value

Natural diamond jewelry sales rose 10% against the prior June. The composition tells the story: average retail sale jumped 19% while unit sales fell 8%. Loose diamonds fared better on volume, with gross sales up 15%, average sale up 16%, and units down just 1%. In plain terms, fewer natural diamonds are leaving the case, but the ones that do carry a meaningfully higher price, whether from larger stones, better quality, or the higher gold cost of the mounting.

Colored stones lead

The standout category was colored stones, up roughly 30% year over year, outpacing every diamond line. That strength matches what the mining side is reporting at auction and gives independents a growth category that sidesteps the natural-versus-lab-grown diamond argument entirely. Sapphires, rubies and a broadening range of secondary stones have moved from accent to anchor in a lot of retail cases, and the June data confirms the shelf space is paying off. The strength is not confined to the counter, either: the mining side has been reporting firm demand for colored rough at auction, which suggests the category has room to run rather than a one-month spike. For retailers weighing where to allocate open-to-buy dollars in the back half, colored stones are the rare line showing both dollar and unit momentum at once.

Lab-grown keeps taking units

Lab-grown diamond jewelry continued to grow on both revenue and units, each up about 23%, though it still represents a small share of most independents' total business. The pressure remains on price: a one-carat lab-grown stone now sells for roughly $750 to $1,000, down about 74% from 2020, as production capacity keeps outrunning demand. For retailers, lab-grown is still a unit driver and a margin question rather than a store saver, and the June split between natural value and lab-grown volume captures the two-track market cleanly.

Behind the average ticket

Part of the rising average sale is gold. With bullion holding near record levels for most of the year, the metal content of a finished piece costs more before a single stone is set, and retailers have passed that through. The rest is mix: shoppers who do buy are stepping up in quality, a trend the industry flagged coming out of the JCK show season and one the June numbers reinforce. The risk is concentration. When growth depends on a smaller number of higher-value transactions, a single soft quarter in bridal or a pullback in gift-giving hits the top line harder than it would in a unit-driven year.

The price-up, units-down year

The June figures extend a pattern that has defined 2026: dollars up, units flat to down. It is a comfortable headline while average tickets keep rising, but it leaves the sector exposed if gold retreats or shoppers stop trading up. Metal did soften this week, as covered in the gold recap, and a sustained pullback in the metal price would drag the average retail sale that has done all the heavy lifting.

Supply is adjusting too

On the rough side, De Beers used its July sight to cut list prices closer to secondary-market levels, unwinding a premium that had run anywhere from 5% to 50% depending on the category. That should filter through to steadier polished prices in the pointer sizes independents actually stock. The colored-stone strength, meanwhile, comes as the largest miner in that segment reshuffles its leadership, a change detailed in the Gemfields report, and against a broader week recapped in the trade wrap. The question for the second half is whether unit counts ever recover, or whether the American jeweler's growth stays entirely a function of price.
