Kashmir Sapphires
Nestled in the breathtaking landscapes of the Himalayan region, Kashmir sapphires stand as a testament to nature's artistry and geological wonder.
Locked in History
You cannot visit a Kashmir sapphire mine; not unless you have mastered the art of time travel. These mines, which were established in the late 19th century in the vertiginous snow-capped Zanskar Range of the Himalayas, have lain dormant for nearly 150 years. Avalanches, earthquakes and politics have sealed their fate, making the gems they once produced exquisitely rare.
Following a landslide in 1882, a number of blue stones were discovered on the steep slopes of a Zanskar valley. Samples were quickly taken to the Indian Museum who confirmed that the blue stones were indeed Sapphires. The Maharaja of Kashmir subsequently purchased the land, and the remote valley was mined intensively until 1889, when the supply was exhausted, leading to an official halt to mining in the region.
The remote area of the mine remains heavily guarded by private security to prevent thieves from entering and searching for the legendary gems. Despite numerous attempts over the centuries, gemmologists have been unable to locate another deposit in the area, making high-quality Kashmir sapphires highly sought after. Only a handful of stones weighing over five carats exist in the world.
Cut for Candlelight
Kashmir sapphires are considered the standard for all sapphires; owning one means possessing a piece of history.
Given the limited life of the mine many of these fine gems were cut between 1882 – 1889. Old mine cuts are the most prevalent shape as these featured large open facets that enhanced the stones velvety, "sleepy" qualities and meant they performed well by the candlelight of the day.
With many stones of this age showing wear, some have been recut into modern round brilliant or cushion cuts as these shapes enhance the gem's inherent brilliance and unparalleled blue hue.
There are two key defining characteristics that distinguish Kashmir sapphires from other types of sapphires:
1) Cornflower blue hue: They exhibit a unique, intense blue hue with subtle violet undertones.
2) Silky / Velvety Appearance: This results from tiny inclusions within the the gem that scatter the light
Chemistry Creating Colour
Kashmir sapphires exhibit their distinct blue colour due to trace elements within the crystal structure of corundum, the mineral from which sapphires are composed. In the case of Kashmir sapphires, the presence of iron and titanium impurities gives rise to their deep blue hue.
Additionally, the specific geological conditions and unique environment of the Kashmir region, particularly in the Zanskar Range, play a crucial role in nurturing these sapphires with their exceptional and sought-after velvety blue colour.
Kashmir Sapphire History
In 1949, a remarkable 152.35ct Kashmir sapphire in a cabochon cut was featured in a platinum panther brooch designed for Wallis Simpson, the Duchess of Windsor.
