Sharjah24 – AFP: A sapphire-and-diamond brooch and matching ear clips which once belonged to Russia's Romanov imperial dynasty were snapped up at a Sotheby's auction Wednesday for nearly $900,000.

The jewels, which belonged to grand duchess Maria Pavlovna the Elder (1854-1920), the aunt of the last tsar, Nicholas II, were smuggled out of Russia for safekeeping during the 1917 revolution in which the tsar, his wife and their children were massacred.

"The storied history of the Romanov jewels undoubtedly proved the power of provenance, with collectors from around the world vying for the winning bid," Sotheby's head of sale Olivier Wagner said in a statement.

They went for 806,500 Swiss francs ($885,000, 765,000 euros) including premiums at the Geneva auction -- far more than their estimated value of between $300,000 and $500,000.

Dating from around 1900, the brooch contains an oval sapphire from Ceylon, now Sri Lanka, weighing 26.80 carats.

The ear clips have step-cut sapphires weighing 6.69 and 9.36 carats respectively.

During the Russian revolution, Maria Pavlovna, who had a legendary passion for jewels, entrusted her jewellery to British diplomat Albert Henry Stopford.

Dressed in workman's clothes, Stopford had collected the jewels from Vladimir Palace in Saint Petersburg. He dismantled them, folding the pieces into old newspaper for protection.

The aristocrat and antiques dealer set out for London on September 26, 1917 carrying 244 pieces of Maria Pavlovna's jewels in a bag.

Among them were the sapphire brooch and earrings, and the Vladimir Tiara, now owned by Britain's Queen Elizabeth II.

The jewels were passed to her daughter, princess Elena of Greece and Denmark, and then down through the family until they were first auctioned by Sotheby's Geneva in 2009.

Back then, they were purchased by a European aristocratic family for almost $500,000.
