GENEVA, Nov 2 (Reuters) - The largest internally flawless fancy vivid blue diamond ever put up for auction could sell for up to $50 million at a Christie's sale of rare jewels in Geneva on Nov. 7, the auctioneer said on Thursday.
Known as "Bleu Royal," this vivid blue diamond - which is set in a ring - is among the rarest ever to be unearthed.
"What makes Bleu Royal so rare and special is its size.
In 2016, Christie's sold a rare, 14.6-carat blue diamond known as the "Oppenheimer Blue" for more than $57 million.
Two years ago the watch, now valued at between 1 million and 2 million Swiss francs, sold at auction for $2 million Swiss francs ($2.2 million).
