ABU DHABI: A rare blue diamond valued at $20 million went on pre-auction display on Tuesday in Abu Dhabi.
The 10-carat Mediterranean Blue, which will go on sale in Geneva next month, is the showpiece of a collection estimated at $100 million.
“Included in the group are the largest flawless diamond in the world ... the second-largest red diamond known to exist and several diamonds over 100 carats,” Sotheby’s auction house said.

The polished stones were on display in Abu Dhabi’s Saadiyat Island cultural district on Tuesday next to lavish jewelry, including a white-diamond encrusted necklace featuring a 100.26-carat pear-shaped brown diamond pendant.
The blue diamond will also be showcased in Taipei, Hong Kong and New York before its exhibition and sale in Geneva in mid-May.
“At the top of the rarity pyramid are blue diamonds,” said Quig Bruning, head of jewels for Sotheby’s in North America, Europe and the Middle East.
“Diamonds of exceptional color and size are by definition wonders of nature that seldom occur, so their presence at auctions can only be infrequent.
“Such diamonds were rarer than usual on the market in the past year or so, which makes the sale of the Mediterranean Blue an even more exciting event.”
