A magnificent tiara of natural pearls and diamonds, which has been in the same Italian royal family for more than 150 years, is expected to fetch as much as £1 million at an upcoming Sotheby’s auction. Vogue explores some of the most spectacular tiaras sold at auction over the past decade—and why, for a certain crowd, they’ll always be a desirable piece

“A tiara is the ultimate status jewel,” says Repellin. They have been worn for centuries as a symbol of status and power. The ancient Romans wore wreaths of gold to denote their social standing, and it was a fashion revived by Napoleon Bonaparte in his bid to emphasise his imperial status at the end of the 18th century. Napoleon’s wife Joséphine ordered her tiara from Chaumet, and the Parisian jewellery house has been synonymous with head ornaments ever since, with more than 3,000 models of past creations in its archives. 

“The tiara is quite literally the crowning glory, it guarantees you will be the centre of attention no matter where you are in the room,”  says Jean-Marc Mansvelt, Chaumet’s chief executive. He says clients, particularly in Asia and the Middle East, buy them for weddings and special occasions – even to wear to board meetings as a demonstration of their power. “We had a client a few years ago who bought two tiaras, so his daughter could choose one to wear at her wedding,” says Repellin. Just as aristocratic families in the past demonstrated their importance with the display of an exquisite tiara crafted from the finest gemstones, it now becomes an heirloom for wealthy families to pass down through their own generations.

While few of us will get beyond a wedding day headpiece—or at best a Simone Rocha pearly headband—we can at least fantasise about royal status with an Instagram filter Sotheby’s has launched to celebrate the auction. Available on Sotheby’s main Instagram handle @Sothebys, and its dedicated jewellery account @SothebysJewels from today, the filter enables followers to virtually “try on” the tiara against the 3D background of an Italian Palazzo, and capture a picture of themselves wearing the head piece.

We will have to wait until May to see whether this tiara will break any records, but in the meantime, keep reading to see the best-selling tiaras at auction from the last decade. From the collections of ancient royal families to one sported by Elizabeth Taylor at the Oscars, they demonstrate that the tiara’s appeal is as strong today as it ever was.

The Sotheby’s Magnificent Jewels and Noble Jewels auction will take place in Geneva on May 11.
