Grace Kelly’s Diamond Ring

The Cartier diamond engagement ring that Grace Kelly was presented with by Prince Rainier III of Monaco is legendary. It centers on a monumental 10.48-carat emerald-cut stone that, in the decades since, has inspired countless engagement rings – including versions belonging to Elizabeth Taylor, Beyoncé, Amal Clooney, and Anne Hathaway. The part of the story that’s less well known? The fact that the famous diamond was not the first engagement ring Kelly received from her husband-to-be.
