Zippeite Locality: Delta Mine (Hidden Splendor), San Rafael District (San Rafael Swell), Emery County, Utah, USA (Locality at mindat.org) Size: 6.4 x 5.1 x 4.5 cm. The yellow patches you see here are probably zippeite (darker yellow) and uraninite (uranium oxide- lighter yellow) - this specimen came from the Delta Mine in Utah, which was mined almost exclusively for uranium; this specimen went to the well-known collection of the School of Mines in Paris. The label has the significant mineral misidentified (or the name changed over 100 years of specimen terminology changes, rather), though it does mention "one new sulfate or yellow uranium?" which we presume to be the zippeite (potassium uranium sulfate) although have not analyzed to confirm 100%. Yes, it is basically yellow uranium species, probably several, and is an interesting historic piece. Mineral

Image of the assemblage of bismuth minerals from Nagybörzsöny, Hungary. (a) Reflected light, one Nicol. Note that the reflectance and colour of zipserite and bismuthinite are very similar. A small BSE image was adjusted to match the orientation and size of the reflected-light image. The dashed lines are guides for the eye. The section used is #AR2-3e, the holotype material, deposited under the catalogue number MMUK 7670 at the Comenius University in Bratislava. Mineral

:Zirsilite-(Ce) is an exceptionally rare complex cyclosilicate that is only found in four localities in the world. The type locality is in Tajikistan, but some of the best known specimens are those from the Sagasen Quarry in Norway. The species gets its name from its chemical composition of zirconium (Zr), silicon (Si) and cerium (Ce). The piece hosts micro burnt orange zirsilite-(Ce) with black aegirine on sodalite matrix. We have photographed the specimen with a Canon MP-E 65 mm macro lens to better illustrate the quality and enhance the detail. Size: 4.1 x 4.1 x 2.3 cm. Locality: Sagåsen Quarry, Sagåsen, Mørje, Porsgrunn, Telemark, Norway Mineral
