About Star Sapphire Gemstones

The star effect in sapphire is caused by fine, needle-like inclusions of rutile aligned within the crystal. When properly cut, these inclusions reflect light to form a distinct star pattern on the surface.

Star sapphires occur in a variety of colors, including blue, black, gray, pink, and white. Important sources include Sri Lanka (Ceylon), Myanmar, Thailand, Madagascar, and India. Some star sapphires may be heat-treated; excessive heating can reduce or remove the star, so treatment disclosure is essential.

Natural star sapphires with a centered, sharp star and good translucency are especially valuable.
