The Incredible Story Behind Meghan's Gigantic Ring From Princess Diana

As if the slinky halter-neck Stella McCartney gown, nifty sports car, and a rather dashing prince in a velvet tuxedo weren't enough to extend our gasps until at least 2 p.m. tomorrow, Meghan Markle just piqued our interest even further en route to the wedding reception by waving an enormous emerald-cut aquamarine-and-diamond ring into view—a ring so mighty that not only could it warrant its own zip code, but it is also important enough to lay claim to its own heartwarming royal tale.

This beautiful whopper of a gem was first owned by Diana, Princess of Wales. It was custom-made following her 1996 divorce from Prince Charles: She felt it inappropriate to still wear the original sapphire ring from Garrard & Co. and commissioned an alternative to better suit her tastes at the time. "She always chose diamond jewellery that was meaningful to her—she was very intentional with her jewellery choices and made sure they were the best representation of those meaningful moments," Grant Mobley, a gemologist and director at Pluczenik, tells The Express, estimating that one would expect to pay around the $100,000 mark today for the unique creation.
