Material Good Marks 10th Anniversary with Boston Boutique and Sabalenka Partnership

Material Good celebrated its 10th anniversary with simultaneous retail expansion and a high-profile ambassador appointment, opening a 2,500-square-foot boutique on Newbury Street in Boston’s Back Bay in February 2026 and naming world No. 1 tennis player Aryna Sabalenka its brand ambassador. Sabalenka made her first appearance for the house at the Australian Open in January 2026 wearing a custom necklace and matching earrings, signaling the partnership’s public debut just weeks before the Boston boutique opened.

The Boston boutique’s interior ambitions are as specific as its square footage. The 2,500-square-foot store includes a second-floor gathering space, a fireplace lounge described as having a vintage vibe, a communal dining table, and a private salon—features that frame shopping as a social, appointment-driven experience rather than a conventional retail visit. NationalJeweler labeled the Boston opening “Material Good Opens Third Location,” and noted that Beverly Hills was chosen as the location for the brand’s first store, designed as a “private residence for modern monarchs,” positioning Boston as the next chapter in a boutique-led expansion.

The ambassador relationship grew from an on-court provenance rather than a staged campaign. Sabalenka first wore Material Good during her 2025 U.S. Open victory and “a relationship developed naturally from there,” the company has said; she will represent Material Good on and off the court throughout the 2026 season, including at Grand Slam tournaments and other events. The timing aligns the retailer’s anniversary year with a global visibility strategy that ties its jewelry to sporting moments and red-carpet circulation.

The pieces Sabalenka wore make that strategy literal. JCK reported that “Aryna Sabalenka’s Australian Open necklace by Material Good has a 4.3 ct. oval blue sapphire encircled by 1.31 cts. t.w. white diamond cobblestone pavé,” a specification that pairs a substantial corundum center with a delicate pavé halo often used to amplify color and presence. Trade coverage also ran images captioned “Aryna Necklace Material Good” alongside renderings of the Boston interior, underscoring how the brand is staging both product and place.

Material Good is framing the anniversary as an opportunity to broaden product access while deepening watch brand relationships. Teresa Panico, the company’s director of marketing and fine jewelry, said, “We can’t wait to bring the Material Good experience to these cities while continuing to expand the Material Good jewelry collection, deepen our relationships with the incredible independent watch brands we’re proud to partner with, and provide access to rare vintage through our Found & Collected jewelry drops and our curated collection of pre-owned watches.” Panico also confirmed that additional boutiques are planned for Dallas and “another location” in 2026.

The company’s press materials emphasize that it is “redefining the fine jewelry and watch experience” and list coverage across trade and consumer outlets including JCK, NationalJeweler, WWD, Town & Country, GQ, L’Officiel, Forbes, and Vogue. As Material Good moves from Beverly Hills to Back Bay and toward Dallas, its tenth year will be measured by how successfully its Found & Collected vintage drops, curated pre-owned watch offerings, and the visibility provided by Sabalenka translate into sustained demand for both one-off jewels and a new roster of boutique destinations.
