Greenwich St. Jewelers and Jewel Boxing launch charms for layering

Greenwich St. Jewelers and Jewel Boxing have shifted their collaboration from a pre-styled necklace capsule into a build-your-own charm system, and the change is the story. The fourth partnership between the Manhattan jeweler and Xarissa B., the creator behind Jewel Boxing, went live on June 24 with collectible gemstone charms sold individually, plus bead strands and chains designed to be worn across necklaces and bracelets.

The current assortment is built for accumulation rather than one-and-done styling. Greenwich St. Jewelers’ collection page lists 18 products, including frame charms, bead strand necklaces, a cable link chain and an omega chain, with prices ranging from $940 to $12,200. The entry point is a mixed orange opal bead strand necklace at $940; the highest listed piece is a Muzo emerald Laurel frame charm at $12,200. Greenwich St. Jewelers describes the line as a limited-edition vibrant jewelry collection featuring bold designs and colorful gemstones, a formulation that fits the market’s move toward pieces that can be layered, reset and recombined over time.

That modularity marks a clear evolution from the pair’s 2024 collaboration, which was a seven-piece necklace capsule. In the new release, the emphasis falls on interchangeable components and on styling that extends beyond a single neckline. Colored gemstone charms can be worn with a gold chain or a strand of gemstone beads, then carried onto existing necklaces or bracelets, making the collection feel closer to a private jewelry wardrobe than a fixed edit. Even the names, from Hyacinth to Hydrangea, lean into a botanical, collectible language that invites stacking and sorting.

For Greenwich St. Jewelers, the launch also reflects a house with deep roots and a polished present tense. The business opened on Greenwich Street in Manhattan’s Wall Street area in 1976, and Jennifer Gandia and Christina Gandia Gambale now run the brand from a 1,500-square-foot flagship at 93 Reade Street in Tribeca, opened in 2022 and described by the sisters as a modern jewelry sanctuary. The jeweler says it has been dedicated to uniting couples with rings for more than 49 years, and its site pairs that heritage with the line, "For you, no matter who you are." Xarissa B. is listed on the retailer’s site with more than 40,000 followers across Instagram and TikTok, a built-in audience that helps explain why this collaboration now reads less like a necklace drop and more like a repeat-purchase framework for personal layering.
