  • Description

    An unheated star sapphire is a natural sapphire that has not undergone any heat treatment, a common process used to enhance the color and clarity of gemstones. These sapphires are notable for displaying a unique star-like pattern, known as asterism, which is caused by light reflecting off needle-like inclusions of the mineral rutile within the stone. This star effect typically features six rays, though it can sometimes exhibit twelve.
