Star rubies and sapphires show a bright six-legged star in the dome of
their cabochon. The stars, like the eye of a cat's-eye, are formed by light
reflecting off tiny inclusions in the stone. The value of star rubies and
sapphires are influenced by two things: the intensity and attractiveness of
the body color and the strength and sharpness of the star. All six legs
should be straight and equally prominent. Star rubies rarely have the
combination of a fine translucent or transparent color and a sharp
prominent star. Star sapphires are more common but still very rare with
fine color. Star rubies and sapphires are becoming more rare as most
rough today is cut into faceted stones after heating instead of being cut
into cabochons to display the star. Stars are very collectible as a result.
