Opal Earrings Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Accirrch is the best-performing opal earrings brand in July 2026, moving 700 units across 1 ASIN for 31.1% of Top 10 volume. Thiswhyimbeauty follows with 500 units (22.2%), ahead of CiNily on 300 units (13.3%).

With 8 brands splitting the Top 10 and 66.7% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $6.64 to $14.99, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, 2 ASINs forced its way in: B0DMRF4L1P booked 100 units at $26.99, with ▲ 100.0% MoM change.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
