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.
