Christie Brinkley revisits Billy Joel engagement ring in memoir interview

Christie Brinkley’s Billy Joel engagement ring has become the kind of jewel that outlives the romance that gave it shape: a square-shaped diamond, introduced in August 1984, and still vivid enough in Brinkley’s memory that she calls it one of the most beautiful rings she has ever seen. Its current whereabouts are not publicly known, but the ring’s disappearance has only sharpened its aura.

The proposal came at the height of one of the most watched celebrity pairings of the 1980s. Brinkley and Joel married in March 1985, on a boat in New York Harbor, after meeting in St. Barts two years earlier. Their daughter, Alexa Ray Joel, was born that December. The marriage lasted nearly 10 years before the couple divorced in August 1994, but the story never quite ended there. Brinkley and Joel have remained amicable, and that lingering warmth is part of why the ring still resonates: it belongs not just to a relationship, but to a long afterlife in public memory.

The ring itself fits its era with unusual clarity. A square-shaped diamond has a harder, more graphic profile than the rounded solitaires that dominate many modern proposals. In the mid-1980s, that kind of geometry read as polished and assertive, the sort of statement piece that matched Brinkley’s supersized celebrity visibility and Joel’s status as one of pop’s biggest names. It was less about restraint than about presence, a jewel meant to be seen from across a room or a camera lens.

Brinkley’s memoir, Uptown Girl, brings the ring back into the frame by reopening the romance that made it famous. In the book, she says Billy Joel’s “Uptown Girl” began as a “mystery girl” song and was later finished in her honor after their relationship began. She has also said that speaking about Joel was the hardest part of writing the memoir because she still cares about their friendship, and that she wanted to hold both the joy and the difficulties of their life together, including his drinking.

That balance is what gives the ring its force now. Vintage celebrity jewelry has become more compelling when it carries a real biography, not just a carat count, and Brinkley’s diamond has both scale and story. It is a relic of 1980s engagement-ring taste, but also a sentimental object that survived the marriage, the divorce, and decades of fame, which is precisely why it still holds attention.
