The Premier Blue, a 7.59ct round brilliant-cut internally flawless fancy blue diamond is a rarity owing to its cut and colour, and is the first stone of its kind to appear at auction. The diamond will appear at Sotheby’s Magnificent Jewels and Jadeite Autumn Sale on October 7 at the Hong Kong Convention and Exhibition Centre.

Sotheby’s deputy chairman of Asia and chairman of International Jewellery Asia, Quek Chin Yeow, said: “Sotheby’s has been entrusted with many important blue diamonds and holds the current per-carat price record for fancy vivid blue diamond at auction (with the sale of a 6.01-carat fancy vivid blue diamond which achieved US$1,686,505 per carat in Hong Kong in October 2011).

"This Autumn we are thrilled to offer The Premier Blue, an unusually beautiful and rare treasure of round brilliant cut as well as Internally Flawless clarity. A befitting celebration of Sotheby’s 40th anniversary in Asia, the debut appearance of such a rare Fancy Vivid blue diamond as The Premier Blue at auction offers an unprecedented collecting opportunity for connoisseurs worldwide.”

The Sotheby’s Hong Kong Magnificent Jewels and Jadeite Autumn Sale 2013 is specially curated to celebrate the auction house’s 40th anniversary in Asia. The sale includes a selection of old and new world jewellery including significant pink, yellow, and colourless diamond pieces, rubies, emeralds, Kashmir sapphires, natural pearls, and jadeite. Approximately 330 lots are on offer in an estimated HK$600 million/US $80 million.

The Premier Blue will be previewed around Asia as well as in Geneva, London, New York and Doha before the auction.
