This is a strange and gorgeous combination specimen from Dalnegorsk. It features a very large compound crystal of sphalerite, with dozens of flashy faces, which are accented by golden chalcopyrite that has filled the recesses between the sphalerite faces! You can see some galena on the underside as well, a common association with Dalnegorsk sphalerites.
