For its 40th anniversary in Asia, Sotheby’s Hong Kong is pulling out all the stops to make its Magnificent Jewels and Jadeite autumn sale one for the record books. Leading the long list of headline-worthy highlights is The Premier Blue, the largest Round Brilliant Cut Internally Flawless Fancy Vivid Blue diamond ever to appear at auction. At 7.59 carats, this stunning blue diamond is also the largest of its kind to be graded by the GIA.
Quek Chin Yeow, Deputy Chairman, Asia, and Chairman International Jewelry, Asia, adds, “Sotheby’s has been entrusted with many important blue diamonds and holds the current per-carat price record for Fancy Vivd 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).” Remarking on the significance of the diamond to Sotheby’s, Yeow believes it is “a befitting celebration of Sotheby’s 40th anniversary in Asia [that]offers an unprecedented collecting opportunity for connoisseurs worldwide.”
While round brilliants continue to be the preferred cut for colorless diamonds, the shape is exceptionally rare in colored diamonds due to the high wastage of diamond rough. Typically, a diamond rough of at least double its fashioned carat weight is required to fashion a diamond into this popular and desirable shape.
The natural coloration of blue diamonds is caused by the presence of the trace element boron, with many blue diamonds exhibiting grey or black hues or having an uneven saturation with areas of colorless windowing. The Premier Blue’s rarity is enhanced by its even and saturated pure blue hue. After combining The Premier Blue’s never-before-seen cut, impressive size, saturated pure color and striking high clarity, this extraordinary blue diamond is seemingly rarer than rare itself and sure to cause quite a commotion when it lands on the auction block this October.
Even with a such showstopper at the forefront, the other highlights of the sale certainly don’t disappoint. Yeow comments that “our selection this Autumn is marked by unique pieces of illustrious provenance as well as inimitable style and glamour. We are delighted to offer an extravagant set of two jadeite bead necklaces from Republican Shanghai, a Cartier pink diamond ring from the estate of Madam Ji Ing Soong, an extremely glamorous Cartier peacock brooch from a royal private collection, and a unique 8.03-carat Burmese ruby ring which is the result of collaboration between Sotheby’s and celebrated Asian jewelry designer Cindy Chao.”
The list of additional highlights seems to go on forever, so here are the most notable jewels, including those mentioned by Yeow:
