AN IMPORTANT SAPPHIRE AND DIAMOND RING, BY HARRY WINSTON
Set with a cushion-shaped sapphire, weighing approximately 16.36 carats, flanked by half-moon and baguette-cut diamonds, to the circular-cut diamond gallery, mounted in platinum, ring size 4
Signed Winston and with maker’s mark for Harry Winston
Accompanied by report no. CS 1077105 dated 11 July 2016 from the AGL American Gemological Laboratories stating that the sapphire is of Kashmir origin, with no gemological evidence of heat and clarity enhancement; also accompanied by a letter stating that the sapphire possesses a richly saturated blue colour that distinguishes a top Kashmir sapphire. Further augmenting the significance of this particular Kashmir sapphire is the fact that it is in excess of 16 carats, a substantial weight category, for sapphires of this exclusive provenance

Premium report no. 86488 dated 27 June 2016 from the SSEF Swiss Gemmological Institute stating that the approximately 16.00 carat sapphire is of Kashmir origin, with no indications of heating and the colour of this sapphire may also be called royal blue in the trade; also accompanied by an appendix stating that the sapphire possesses extraordinary characteristics and merits special mention and appreciation. The sapphire exhibits an important size and weight combined with a highly attractive and saturated blue colour and very fine purity. The few tiny inclusions found by microscopic examination are the hallmarks of sapphires from the reputed historic deposit in Kashmir, located in a remote part of the Himalayan Mountains in India. The velvety blue colour of this sapphire, poetically also called royal blue in the trade, is due to very fine and subtle inclusions and a combination of well-balanced trace elements in the gemstone, which are typical and characteristic for the finest sapphires of Kashmir. A natural sapphire from Kashmir of this size and quality is rare and exceptional

Report no. 16067201 dated 26 June 2016 from the Gübelin GemLab stating that the sapphire is of Kashmir origin, with no indications of heating; also accompanied by an appendix stating that the sapphire possesses a richly saturated and homogeneous velvety colour, combined with a high degree of transparency, and a finely proportioned cut. In addition, this remarkable gemstone has been spared thermal treatment. Such a combination of characteristics is rare in natural Kashmir sapphires of this size
