Set with an oval mixed-cut sapphire, weighing 22.98 carats, flanked by a pair of half moon-cut diamonds, mounted in platinum,the diamonds estimated to weigh approximately 1.75 carats in total, ring size 6¼.. Sold for HKD 6,144,000

Accompanied by a certificate from Gübelin, stating that the 22.98 carats sapphire is natural, of 'royal blue' colour with no evidence of heat treatment and originates from Burma (Myanmar). Report number 0910577, dated 2nd November 2009

Accompanied by a gemmological report, showing the same findings. Report number CS41301, dated 18th November 2009

The colour of this superb Burmese sapphire brings to mind some of the most important Burmese sapphires in the world; the Rockefeller sapphire ring and the Duchess Of Windsor brooch with the panther surmounting a sapphire sphere by Cartier.

As demonstrated by the names associated with the two pieces just mentioned, connoisseurs appreciate 'royal blue' sapphires from Burma, as they tend to possess a much richer colour and saturation than material from different origins.

The 'royal blue' sapphire set in this ring displays an intense vivid, well balanced and evenly saturated blue colour with a spectacular play of life.
