The quality of the Cassiterites on this specimen is outstanding. They’re very sharp, smooth and lustrous, and good sized for the material! Several fantastic, very sharp, eye-catchi ng, highly lustrous, jet-black to golden colored, amazingly well-formed cyclic twinned crystals are aesthetically intergrown with tan compressed rhombohedra of Siderite. There are actually a few small Quartz crystals on the piece as well for a final touch. Very minimal damage, and top-notch both from the standpoint of excellence and associations!
