The tiara is expected to fetch around 1.2 million CHF at auction—prospective bidders (and everyone else) can try before they buy

A pearl and diamond tiara, once owned by Maria Vittoria Carlotta Enrichetta Giovanna dal Pozzo della Cisterna, Duchess of Aosta and Queen of Spain, is listed for auction at Sotheby's—and interested bidders, as well as anyone else who has ever wondered what they would look like in royal headdress, can try before they buy. Because this royal tiara is now also an Instagram filter.

In a post on the Sotheby's Instagram account, the million-dollar piece has been dubbed "the first royal tiara anyone can wear." Part of the Royal European Family jewellery auction in Geneva this May, a likeness of the tiara has been made into an Instagram filter—and anyone on the social media platform can try on the tiara "inside" an Italian palace.

So far, some of the #tiaraselfies have been pretty great.

The tiara features graduated scroll motifs set with cushion-shaped diamonds, which frame drop-shape natural pearls. The top of the tiara is detachable and Sotheby's notes indicate that this detached piece can be worn as a necklace. The piece was designed and made by Musy for Maria Vittoria, who married Prince Amedeo of Savoy as a 19-year-old girl in 1867. In a wild twist of fate, Prince Amedeo ascended to the Spanish throne in 1870, but abdicated after three years. Maria Vittoria died at age 29 in Italy.
