Alabama State Symbols - State Gemstone Blue Star Quartz

Designated in 1990, the state gemstone of Alabama is star blue quartz. It's a very specific type of quartz that appears to be clear to milky, but shows its blue color in direct sunlight. It is a macrocrystalline (big crystal) quartz with fibrous inclusions of magnesiorbecktite or crocidolite. These fibrous inclusions cause asterism (a star to show on the surface) when properly cut and polished. Some of these blue stones have multiple stars or single stars with up to 10 rays!
