The star effect that you see in a variety of gemstones is called Asterism. It is most comely found in corundum (Rubies and Sapphires) but other minerals occasionally show it too and those are accepted to be more rare.
Asterism is an optical phenomenon sheen, that occurs with parallel orientated inclusions: tiny fibers, needles and hollow tubes. The effect of thection on these parallel arranged needles, fibers or hollow tubes is a light streak which runs at a 90° angle over the inclusions. In order for this effect to be seen, the gemstone needs to be cut en-cabochon. Asterism is caused by reflection on inclusions. The inclusions are arranged in different directions causing several streaks of light on the surface of the en-cabochon stone. In general, the inclusions which cause the stars are orientated parallel to the crystal faces. There can be 4-, 6- and 12- pointed stars. For a good effect the rays will be continious not broken.
