"Since their discovery in 1881, the legendary sapphire deposits of Kashmir have acquired a reputation based on a mixture of fact and fantasy that is usually associated with the ancient gem mines of the world. [The locality is] situated in the high Himalaya Mountains of northwest India and described in early reports as “the region beyond the snows”. (…) Few gemmologists would dispute that a fine Kashmir stone displays a character that sets it apart in a world relatively abundant in corundum gems. Over the years, the term Kashmir has come to signify the most desirable and expensive of blue sapphires".
