A large specimen from the older sections of this historic mine, showing fat, robust crystals of willemite - the variety formerly called Troostite. They are fluorescent an intense greeen color. This piece has a good display face of them, sitting on contrasting calcite. The specmen was in the collection of noted collector and author, Captain John Sinkankas, and comes with his handwritten label. It was his first specimen of willemite, dating to over 50 years ago. I bought it from John in the mid 1990s and it was later sold to noted collector and Tucson show activist, Bob Jones, from whom I bought it back only recently. Joe Budd Photos.
