This specimen hosts a HUGE crystal for the species, measuring 2.8 cm - over an inch long! It is up to 8 mm width. The crystal face is complete and undamaged, and the crystal shows off its end-terminations at top and bottom. A major crystal for the species, of some importance, and well above anything you typically see from the locale. This is an older piece that has been in a private German collection for some time. I have not seen a larger example for sale. To be sure about it, I had this tested every which way by Bart Cannon's lab in Seattle, to prove to his satisfaction that it is rathite, and not the slightly more common lengenbachite or baumhauerite.
