Rainbow Lattice Sunstone is one of the rarest stones in the world that exhibits a rare combination of aventurescence, adularescence and a distinctive iridescence lattice pattern. The aventurescence in the stone is caused by small inclusions of a mineral with a highly reflective surface. Aventurescence creates a sparkly, metallic-looking luster which is caused by flat, reflective inclusions. Adularescnece in the stone is an optical phenomenon exhibiting a sheen or schiller effect which is caused by the below surface of a stone. The colours seen in the stone depends on the thickness of the layers. Both aventurescence and adularescence are hard to find in the same stone. Australian Rainbow Lattice Sunstone is a must-have in your rare gem collection.
