Quartz, Hubeite, Pyrite Locality: Ezhou Prefecture, Hubei Province, China (Locality at mindat.org) Size: 14.4 x 12.9 x 6.9 cm. A large, ornate and quite unusual Chinese specimen out of the J.R. Glover Collection. The quartz crystals contain little black inclusions of hubeite, a strange sorosilicate mineral only recently identified (found first at the Daye Mine, also in Hubei Province, and named after this province). At some point the quartz crystals here were sprinkled with these little black hubeites, and then growth continued, so they are now enclosed under thin sheet of quartz (rather than being on the surface of the crystals) as inclusions. Shiny golden pyrite adds an attractive accent to the specimen. Mineral

Hulsite Locality: Brooks Mountain, Seward Peninsula, Nome Borough, Alaska, USA (Locality at mindat.org) Size: miniature, 4.9 x 4.0 x 3.2 cm Hulsite Hulsite is an extremely rare iron borate, reported back in the 1890s. I have seen only half a dozen specimens for sale in my life, of which this is the largest and richest by far. All I have seen came from the same locality, its type locality. This piece is rich in massive and microcrystalline material. Ex. John White Collection. Mineral
