Ex. Ross Lillie
A gorgeous specimen of really glassy sphalerites from one of the older mines in the district circa 1950s-1960s (per Ross Lillie label). Perched on corroded galena along with minor quartz, this intergrown plate of splendent black sphalerite crystals, to 1.8 cm in length, exhibits gemmy reddish orange highlights. It is nearly pristine all around, and it reflects light phenomenally in person - much better than indicated in the photos. Mined in the late 1950's or early 1960's. RCL0475
