A complicated specimen loaded with many minerals. The main mineral is nut brown, striated Jahnsite-(CaMnMg). This is the original Jahnsite prior to the breakout of additional Jahnsites based upon the major elements occupying the structural sites. This particular Jahnsite is about the only one that you can visually identify at the Tip Top. The rest aren't necessarily identified easily based upon color. There is another Jahnsite on this specimen, which is yellow and much smaller. Additionally there is black, acicular Rockbridgeite & pink Hureaulite crystals. The Hureaulte is about 2mm and is pink with yellow Jahnsite on the surface and pseudomorphing. There is also purple Leucophosphite.
