HONG KONG.-Christie’s announces that it will offer a rare diamond of 101.27 carats in the forthcoming Spring Hong Kong jewellery sale on May 28. This extraordinary gem is the largest colourless diamond to appear on the auction market in the last 18 years and is expected to realize in excess of US$6 million. It will be unveiled as part of Christie’s Spring Masterpieces Exhibition held in London February 23 – 27.

“Only 3 colourless diamonds of over 100 carats have ever appeared at auction, all sold in Geneva. With Asia becoming such a vibrant market, it is fitting that this rarest gem should be offered on May 28th to the growing number of collectors in this region," said Francois Curiel, Christie’s Chairman of Jewellery.

Vickie Sek, Director of the Jewellery and Jadeite Department, Christie’s Asia continued, “As auction leaders in Asia, we hold many records in the jewellery field, but never before were we able to offer such an important stone in Hong Kong. Its appearance on the market has already created a sensation."

This exceedingly rare diamond was cut from a daunting 460 carat rough to its present 101.27 carats. Its unusual modified shield shape flaunts 92 brilliant facets. It is accompanied by a Report from the Gemological Institute of America (GIA) certifying that it is F colour together with the highest standard for polish and symmetry, both rated Excellent, a testament to the skill of its cutters. Due to surface graining (a natural growth inclusion) that is imperceptible to the human eye, this exceptional Internally Flawless diamond is rated VVS1 (very very slightly imperfect 1st degree) for clarity.
