Kate Middleton Just Brought Back Queen Mary's Emerald Necklace From the 1920s

Welcome to America, Will and Kate! The Prince and Princess of Wales have touched down on U.S. soil for the first time in eight years. They've arrived in Boston for a three-day tour, which culminated in the second annual Earthshot Prize Awards honoring leaders in environmentalism. For the glamorous red carpet ceremony, Kate Middleton rented a dress from Hurr—how sustainable!—and brought back Queen Mary's emerald necklace from the 1920s, which was also previously worn by Princess Diana. 

They previously visited New York City in 2014 and Los Angeles in 2011. This is their first appearance in the U.S. since becoming the Prince and Princess of Wales after Queen Elizabeth's passing. For her first outfit of the tour after deplaning, Middleton wore a subdued eggplant-hued pantsuit and classic pumps along with sapphire earrings from Princess Diana's collection. Scroll down to see the photos.

While I love the fact that the Princess of Wales rented a dress for the occasion, my eyes immediately zeroed in on her impressive, historical jewels.

Can you imagine having access to precious heirlooms over 100 years old?

Princess Diana wore the necklace several times, but this was the first time Kate Middleton has been photographed wearing it.

The emerald piece in question sits at the top of Queen Mary's impressive stack of necklaces.

Associate Director, Fashion News

Erin got her start as a Who What Wear intern over 13 years ago—back when the site only published a single story per day. (Who What Wear has since increased that number twentyfold.) She graduated magna cum laude from USC, which is how she ended up moving to Los Angeles from her hometown of San Diego. In college, she also interned at Refinery29, where she was promoted to editorial assistant and then assistant editor. After nearly three years at R29, she came back to WWW in 2016, where she currently holds the title of Associate Director of Fashion News (as well as the unofficial title of resident royal expert—in case you haven't noticed her numerous Meghan Markle and Kate Middleton stories). She spends her days trying to incorporate her idols, Anna Wintour and Roger Federer, into as many stories as possible. Outside of work, she loves tennis, classic rock, traveling, and smothering her dog with affection.
