Large, attractive plate of large crystals (to 3.4 cm) of very lustrous opaque sphalerite with needle quartz and minor chalcopyrite. As shown the photos, the sphalerite has some interesting growth patterns. The bottom of the specimen is flat where it was attached to matrix. There is some contacting and damage around the edges (a result of the specimen extraction), and a few cleaved quartz crystals. However, the large central crystals are in excellent shape and overall the specimen is very good. 11.2 x 8.6 x 2.7 cm.
