Fans of Sophie Ratner’s jewelry include Selena Gomez, Elizabeth Banks and Octavia Spencer, but when the New York-based designer met The Flight Attendant’s Zosia Mamet, both women felt a kinship.

SRJ x Zosia Mamet, a just-released collab inspired by a pearl ring passed down from Mamet’s grandmother, which the actress wears on a chain for safekeeping.

Priced from $270 to $1,975, the four-piece collection comprises three stackable rings in combinations of ethically sourced 14-karat gold, black or white enamel and diamonds, which can be personalized and worn separately or together on the hand or a gold chain.

Ratner and Mamet have been working on the concept since 2019 but delayed the release due to the pandemic. With Valentine’s Day approaching, the duo agreed that the time had arrived. “Everything has been so scary during the past year – but also, personalized jewelry feels even more important right now,” Ratner says. “I feel like the past year has made the concept so much stronger because maybe you’re commemorating the birth of a child, or someone you’ve lost.”

With heirloom jewelry a rising trend among millennials, Mamet agrees that the collection is meant to resonate in much the same way as a vintage ring or necklace.
