Note: Sapphire, a highly-esteemed gemstone, has its finest specimens originating from the mountains of Kashmir. It is a remote region that defines the northern most border between Pakistan, India and China. The gems are formed by the intersecting movement of three prominent mountain ranges： The Himalayas, Karakorums and the Hindu Kush mountains. 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 were ideal for sapphire growth. The resulting gemstone is one of legendary quality and a synonym to the most desirable gemstones. Kashmir sapphires are most famous for its violetish blue to pure blue hue, with moderately strong to vivid saturation and medium-dark tone. Its internal environment has minute internal inclusions – rutile silk – that give the gem a velvety luster and a soft texture which also intensifies its color. The Kashmir gem deposit was revealed after a landslide on a mountain in the Zanskar range of the Himalayas in 1881. Mining was primitive and intensive, and only continued for a brief period between 1881 and 1887 at irregular intervals. The rough yield quantity was small due to extreme elevation, harsh climate, inhospitality and political unrest. The deposit was exhausted by the 1920’s and there have been no new finds in the area. The Kashmir sapphires are talked about in almost a mythical way these days, and provide qualities against which all others are judged.

We are honored in this auction to present lot 2154, an 12.32 carat Kashmir sapphire ring. The well-proportioned oval-shaped sapphire shows an unrivalled depth of color, and is softened by the warm inner glow and a subtle velvety sheen. Kashmir sapphires are indeed an exclusive class of their own, worthy of admirations for the generations to come.
