Tobias Kormind, managing director of Europe’s largest online diamond jeweller 77 Diamonds, shared his thoughts on the jewellery's historic allure: "A scandalous link to Marie Antoinette and the dramatic end of the French monarchy, this historic necklace, which is unusually intact for a Georgian jewel, has it all."

A 300-carat necklace, whose diamonds have been linked to a scandal involving the last French queen Marie Antoinette, sold Wednesday for nearly $5 million at a Sotheby's auction in Geneva.

The necklace containing around 300 carats of diamonds was bought by an unidentified woman who put in her bid over the phone, Sotheby's said.

"There is obviously a niche in the market for historical jewels with fabulous provenances," Sotheby's jewelry specialist Andres White Correal said after a diamond-studded necklace with a possible link to Marie Antoinette's downfall sold for more than double the pre-sale estimate.

Composed of approximately 300 carats of old mine-cut diamonds, the historic piece was once worn during royal coronations and is rumoured to hold ties to the scandal that tainted Marie Antoinette’s reputation.
