|Sapphire is derived from the Latin word for blue, sapphirus. Sapphires were thought to be the gems of the heavens. Saturation is key to determining value. High quality, untreated sapphires of Kashmir or Burmese origin are the most highly prized and are considered investment grade.|
Kashmir sapphires can be traced back to 1881, when a landslide in the northwestern Himalayas revealed outstanding sapphire. By 1887 the deposit was exhausted. Virtually all Kashmir sapphire comes from this initial find. Today they are extremely rare. Kashmir sapphires are a rich, cornflower blue or velvety luminous blue with a silken transparency.
A deep saturated royal blue is the most coveted.
