  • This is one big, complex crystal of sphalerite, typical of the sphalerite from the Elmwood Mine. The faces are very lustrous and, together with the complexity, makes it very difficult to obtain a flattering photograph. One single, deep purple fluorite cube is attached, as well. This photo does not do this specimen justice! It is a great-looking specimen that shows well.
