star sapphire
Six-rayed blue stone
A star sapphire is a sapphire that displays asterism—a star-shaped pattern of light that appears to float across the stone's surface when illuminated.
The effect comes from needle-like inclusions of rutile aligned within the crystal.
The stars typically have six rays, though twelve-ray specimens exist.
Star sapphires are cut as cabochons rather than faceted to best display the phenomenon.
