50 Standout Celebrity Engagement Rings, From Zendaya to Selena Gomez

Megan Fox's engagement ring features her emerald birthstone as well as her fiancé Machine Gun Kelly's birthstone, a diamond. Based on the ultimate love story, MGK designed the ring special for the occasion: "i know tradition is one ring, but i designed it with Stephen Webster to be two: the emerald (her birth stone) and diamond (my birth stone) set on two magnetic bands of thorns that draw together as two halves of the same soul forming the obscure heart that is our love," he wrote on Instagram.
