An exceptionally-rare blue diamond went under the hammer in Geneva late Tuesday, selling for $21.5 million, Sotheby's auction house said. Ahead of its final showing in Geneva on Tuesday, it was unveiled as part of a Sotheby's debut exhibition in Abu Dhabi last month, where it was showcased alongside seven other "extraordinary" diamonds and gemstones collectively worth over $100 million.
