Miniature, 5.4 x 2.4 x 1.2 cm
Nippyo Mine, Yokoneyama, Tochigi Prefecture, Kanto Region, Honshu Island, Japan
A very rare specimen! This huge crystal would be lartge for the species from ANY locallity, but particularly for this old Japanese classic locale it is of incredible size. I believe it to be twinned, as you can see from the unusual habit. There is some minor edge wear on the front, but given the size I think this is permissible. When backlit, it is translucent and looks more gemmy and red, as you can see in the right-hand photo.
