This phenomenon appears as a bright six-ray star that shows and moves on the polished surface of the cabochon-shaped stone when light falls on it. This effect is attributed to the presence of fine needle-like inclusions of rutile arranged in a crossed pattern inside the ruby crystal. The star ruby features the usual red color of ruby with this bright star.
