What makes a Kashmir sapphire special?

Kashmir sapphires come from the Padar Valley in the Himalayas, a deposit that has been essentially exhausted since the early 20th century. Their defining characteristic is a velvety cornflower blue caused by microscopic silk inclusions that scatter light, producing a soft glow unlike any other sapphire origin. Unheated Kashmir sapphires with origin reports from SSEF or Gübelin are among the rarest and most valuable colored gemstones in the world.

What does 'unheated' mean for sapphires and rubies?

Heat treatment is applied to the vast majority of sapphires and rubies on the market to improve color and clarity. An unheated stone retains its natural color as formed in the earth, which collectors and connoisseurs prize as authentic and rare. Unheated status is confirmed by laboratory report from SSEF, Gübelin, or AGL. Unheated Kashmir sapphires and unheated Burmese pigeon's blood rubies command significant premiums over heated equivalents.
