After wearing the pink-tinted diamond for months, Lady Gaga finally called her agent Christian Carino her fiancé while accepting an award at Elle's annual Women in Hollywood event.
Gemologist and diamond expert Grant Mobley previously told Insider that Gaga's "timeless design" featured a rare, high-quality sapphire — as well as a diamond halo — and could have cost more than $300,000.
The musician and Carino eventually split around the start of 2019, as People reported.
