The Ephemeral Mines of Kashmir
A remote valley in the Padar region of Kashmir, amidst the Himalayan mountains between Pakistan and China, is home to one of the greatest gemstones in the world: Kashmir sapphires. The colour of this blue stone is so unique and distinct that was best described by the late Dr. Eduard Gübelin: soft and velvety, scintillating yet bland at the same time; it is a clear, deep blue, enhanced by a gentle admixture of kingly purple. The locality’s extreme altitude gave workers a maximum of ten weeks each year to unearth these heavenly treasures during 1881 to 1887. The short lifespan of the mines reaffirms the legendary reputation of sapphires from Kashmir. Not only are they some of the most beautiful and highly valued wonders of nature, but some of the most scarcely mined gemstones. Natural unheated Kashmir sapphires rank amongst the rarest gemstones on earth.
