Lot description

Set with a cushion-shaped Kashmir sapphire weighing 13.36 carats, flanked by two tapered baguette-cut diamonds, mounted in platinum, ring size 6, signed Bvlgari Accompanied by fitted box SSEF, 2021, report no. 118289, 13.362 carats, Kashmir, no indications of heating, 'Royal blue', also accompanied by SSEF appendix letter titled 'Exceptional Sapphire' AGL, 2021, report no.1116215, 13.36 carats, Kashmir, no heat enhancement, also accompanied by AGL appendix letter Kashmir, a remote region which has the finest specimens and defines the northern most border between China, India, Pakistan and Afghanistan. The gems are formed by the intersecting movement of three prominent mountain ranges including The Himalayas. Above the earth’s surface, the panorama of jagged rocks, glaciers, lakes, and waterfalls is beyond magnificent. What is more, the tectonic movements underneath create complex conditions in Kashmir, where limestone comes into contact with an intruding Pegmatite. The extremely high temperature and pressure, and sometime a rare silicon-free environment was ideal for sapphire growth. The legendarily exquisite sapphires from Kashmir have been disclosed after a rockslide in the Himalaya mountains in 1881. Although Kashmir has produced only a limited number of gems since then, the soft, velvety blue of Kashmir sapphires remains the epitome of this gem variety and is highly regarded by connoisseurs and collectors alike. Gentle and demanding at the same moment, both gleaming and flattering, the typical hue of Kashmir sapphires is among the most sought after of colours. The velvety blue of this sapphire 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 Kashmir sapphire over 10 carat is extremely rare to be found and every time record- breaking. Undoubtedly, this 13.36 carat Kashmir sapphire and diamond ring is one of the finest Kashmir sapphires among the century in honor of its saturated and homogeneous color, high degree of transparency, very fine purity, and a perfect proportioned cut, which could be considered very rare and exceptional.
