Well-formed star ruby from Burma, cut as a high-dome cabochon to properly display a sharp six-rayed asterism. The star is caused by fine rutile silk oriented within the corundum crystal, reflecting light as intersecting rays when illuminated from a single point source. Burmese star rubies are prized for their saturated red body color, centered star, and strong contrast, with classic material coming from Myanmar’s historic Mogok region. The symmetry and clarity of the star indicate careful orientation during cutting, which is critical for maximizing this optical effect.
