4.5 x 2.7 x 2.3 cm. Andalusite variety viridine is an ULTRA-RARE manganese-rich andalusite. This UNIQUE specimen features large, blocky, DISCRETE, grass-green to brown viridine crystals on a bit of matrix. I have NEVER seen another like it and believe it is unheard of! The locality, itself, is UNIQUE - Conquista, Bahia, Brazil. Dr. Fred Pough, famous mineralogist, author and curator must have collected or obtained this striking and unusual piece while in Brazil during World War II. Ex. Elling Collection.
