Heidi Klum and Tom Kaulitz
Supermodel and show host Heidi Klum, 46, and Tokyo Hotel guitarist Tom Kaulitz, 30, began dating in 2018, after a string of failed relationships. Kaulitz popped the question, and Klum, who referred to him as “her first real partner,” was over the moon. The ring is as unique as the couple, with a green center rock surrounded by a halo of diamonds and two cushion-cut diamonds on each side.
Unlike other celebrities, who value their privacy, Klum proudly announced the engagement on her Instagram page with a photo of the ring followed by the caption “I SAID YES.” She also flaunted the ring every chance she had, mostly on red carpet events, until their wedding day arrived in 2019.
