This piece is very special to me. This is a huge sample of Wolframite crystal with Milky Quartz, and chalcopyrite and Mica Crystal. This piece is from the Oregon Mine near Nederland, Colorado. This piece has made me want to go claim the old mine and try to find more of this fabulous tungsten mineral.
