Editor’s Note
As Gemmyo marks its 15th anniversary, the independent jeweler reinforces its commitment to craftsmanship by acquiring a stake in longtime partner Callistorea. This move reflects a broader luxury industry trend of securing artisanal expertise and made-to-order manufacturing.
Gemmyo gives itself a gift for its 15th anniversary. The jewelry brand, one of the few independents in a universe dominated by large groups, took a stake in January 2026 in the workshop Callistorea, located in Saint-Laurent-du-Var (Alpes-Maritimes) and a “historic partner of Gemmyo,” according to a press release.
Securing know-how is a trend in luxury, as illustrated by the case of Kering, which took a 20% stake in Raselli Franco Group, an Italian jewelry manufacturer, earlier this year. But the fact that Gemmyo is doing the same—a company whose turnover is in the tens of millions of euros, according to its CEO Sophie Garric—is proof that the issue is becoming increasingly sensitive in the sector. The matter is even more important for Gemmyo: the brand only works on a made-to-order basis and holds no stock, which requires developing privileged relationships with its partners. A framework agreement with its five French suppliers, including Callistorea, sets delivery times at 3 to 4 weeks, but requires a bit of organization.
Since last year, the brand has faced rising gold prices. “At first, we trimmed our margins, and in February 2026, we applied increases on particularly affected products, such as an all-gold wedding band,” emphasizes the CEO. The brand can benefit from a wealthy clientele that is less sensitive to depressed consumption. But this clientele is relatively limited geographically.
