barite (Chisel) - Clara mine, Oberwolfach, Ortenaukreis, Freiburg, Germany 
 
Well terminated, chisel-shaped barites in excellent condition from the Clara mine. Of particular note is the size of the middle crystal, which is 8.5 cm long and 3 cm thick! 
The orange zoning in the otherwise clear crystals is characteristic.
Wonderfully intact, highly aesthetic collector's piece of this German classic.
