Kashmir sapphires are known for their brilliance, high saturation and velvet-like appearance. The majority of the world's finest and most valuable sapphires have been mined from this region of the Himalayas.
The history of Kashmir began in 1881, when the inhabitants of the Zaskar Mountains at an altitude of 6,000 metres, on the border of Kashmir and India, began to exchange sapphire crystals for salt, weight for weight.
In 1883, the maharajah of Kashmir declared himself the owner of the mines and stopped all private sales. Since then, it is the army that guards the deposit.
The reputation of Kashmir sapphire rests almost entirely on the stones extracted between 1881 and 1887. Thereafter, very few sapphires are produced.
