Chatoyancy and Asterism – A natural celestial like phenomena seen in very rare stones

Northern Lights, gem asterism, chatoyancy: some of the most compelling and extraordinary natural phenomena may share an origin. Our Gem Hunter Don Kogen notes that the Northern Lights primarily come from material in Sri Lanka, which also produces the finest Cat’s Eye and Blue Star Sapphire. He goes on to discuss Star Rubies, Chrysoberyl, Alexandrite, and Moonstone. And of these striking, celestial gemstones, our Gem Hunter touches on the most remarkable varieties—which only occur once in every half a million pieces of rough material.
