Really a nice miniature with excellent Jamesonite crystals in a 1.5 x 1cm area with black 5mm Sphalerite crystals and faint green Fluorite crystals to 6mm (neither of these are mentioned on the label). The labels are older, one from Paris and the other from the Jack Rodekohr collection. Rodekohr was one of the founding members of the Mineralogical Society of Southern California. The label matches the specimen number. Given the fact that is a antimony sulfosalt it may indeed have come from Wheal Boys, a mine rich in antimony.
