Star sapphire is a unique variety of sapphire that exhibits a stunning star-like phenomenon called asterism. This effect is created by the presence of needle-like inclusions of rutile within the stone, which reflect light in a way that produces a star pattern, typically with six rays.

The base color of star sapphires can vary, with blue being the most common, but they can also be found in shades of pink, yellow, and gray. The star effect is most pronounced when the stone is viewed under a direct light source, making it a captivating choice for jewelry.

In terms of metaphysical properties, star sapphires are believed to provide protection, promote spiritual insight, and enhance intuition. They are associated with wisdom and loyalty, mirroring the qualities of traditional sapphires while adding a unique visual allure.
