Legendary Kashmir
Although some Burmese and Ceylonese sapphires are famous, only the Kashmir Sapphire could be named as“King of the Sapphire World”. With an average altitude of over four thousand meters, the mining work is hard in Kashmir due to short annual production time and frequent wars. These make the gem hard to come by. Kashmir sapphires pronouncedly display distinct blue colour and the signature‘velvety’texture caused by the inclusion of silk.
Under magnification, the exsolved rutile of Kashmir sapphires differs from that of Burma and Sri Lankan stones in terms of the size of the crystals. Many appear as tiny dots in snowflake patterns, and magnification of 40x or more is often required to resolve individual crystals. Due to its extremely fine nature, Kashmir rutile provides subtle light scattering without materially affecting transparency, giving these gems their velvety appearance. Sapphires from Sri Lanka, Thailand(especially Kanchanaburi)and Pailin may also exhibit a certain milkiness, making confusion a real possibility. The haziness in Kashmir stones, however, is extremely fine in nature, not enough to seriously degrade the clarity, but just enough to impart the distinctive velvety luster to the stones. With the source is non-existent, these Kashmir sapphire are almost never seen except in the auction market. Most of the Kashmir sapphires that exist in the market were discovered more than 100 years ago. Due to its unquie beauty and rarity, Kashmiri sapphires have always been adored and sought-after by gem connoisseurs. As these superlative sapphires unrivalled among sapphires around the world, the demand for the gem far exceeds supply.
