A dazzling pearl and diamond tiara once owned by a celebrated member of Britain’s de Rothschild empire on Wednesday sold at a London auction for £1,161,250.

The bejewelled item belonged to Hannah de Rothschild, whom was at one time the richest woman in Britain and whom went on to marry dashing aristocrat and future prime minister the Earl of Rosebery.

Three pieces of jewellery owned by the countess of Rosebery were sold at Wednesday’s “Important Jewel Sale” at Christie’s auction house.

A dazzling tiara featuring emeralds believed to have belonged to Eugenie, wife of Napoleon III, sold for a record 11.28 million Swiss francs ($12.80 million) to an anonymous buyer at Sotheby’s.

The diamond and emerald tiara was commissioned by German prince Guido Henckel von Donnersmarck’s for his second wife Katharina.

It was top lot at a sale that netted 78.9 million Swiss francs, third highest for a jewellery sale, the auction house said.

A young Thai jewelry designer has crafted a tiara worth $4.2 million for his pet dog, using precious stones given to him by his mother.

Riwin Jirapolsek, who showcased the tiara at a dog show in Bangkok recently, said he wanted to make something special for Kanune, his 15-year-old male Maltese.

He took almost two months to finish the piece, which is made from titanium encrusted with 250-carats of emeralds and diamonds.

On March 23rd, online jewelry retailer Bidz.com will auction off a gold and diamond tiara designed by the late Gianni Versace to benefit the Aid for AIDS charity, with an opening bid of $699,000 US Dollars.

The one-of-a-kind tiara, which contains over 1,200 diamonds and is worth an estimated $3 million, has been worn by celebrities including Madonna, Amber Valletta and Donatella Versace.

The Versace Tiara, also known as the Tiara, won the prestigious De Beers Diamonds International Award in 1995.
