Mysterious Canary Diamond Ring Discovered in Grandmother's Closet

In November 2025, actress Zosia Mamet uncovered a captivating family heirloom—her late grandmother's canary diamond ring. The ring, which Mamet's mother had given to her husband to propose with, was found the week before Mamet's grandmother passed away.

Mamet's grandmother had been searching for the "canary diamond" in her final days, waking up one night and frantically asking her daughter, Mamet's mother, where the ring was. Mamet's mother, following the doctor's advice to go along with her grandmother's requests, promised to look for it in the morning. The next day, the grandmother's longtime housekeeper found the ring in a shoe box in the broom closet.

The ring, which experts believe dates back to the 1910s or 1920s, has a rare feature—a tiny hole at the bottom of the diamond that was once used to make the stone sparkle more. Neither Mamet nor her mother had ever seen the grandmother wear the ring, adding to the mystery surrounding this family heirloom. Mamet now cherishes the ring, seeing it as a symbol of her grandmother's strength and independence, despite the complicated relationship they shared.
