Locality: Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry; Carrière Mont Saint-Hilaire), Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada FOV 1.3 x 1.5 mm. Via Monteregian Minerals (LH). Stereo pair. MOB coll. The pale yellowish triangular xl in the center is daqingshanite. (It is actually a trigonal pyramid that looks like a shallow tetrahedron.) The xl is less than 0.4 mm on edge. Daqingshanite is a very rare mineral. According to Horvath (Min Rec 1990), it was probably found only once at MSH. I used stereo because the xls are very pale and on a very pale background. Stereo overcomes the lack of contrast to some extent. There are two other daqingshanite xls in the photo but they are even smaller and very hard to spot due to their size and orientation. Again - stereo helps. Mineral

Darapskite (Size: 4.5 x 2.5 x 1.5 cm) Locality: Iquique Province, Tarapacá Region, Chile Darapskite is a rare hydrated sodium sulfate nitrate found in nitrate deposits rich in sulfates. The famous high altitude, arid nitrate deposits of Chile are host to many of the localities. Rarely available, this is a solid block of glassy, pearlescent, translucent and colorless, layered darapskite. Not showy, but an extremely rich and highly representative example of this very rare sulfate. Ex. Columbia University-American Museum or Natural History and Eugene Carmichael Collections. Mineral

Datolite Locality: Charcas, Municipio de Charcas, San Luis Potosí, Mexico (Locality at mindat.org) Size: cabinet, 13.9 x 10.1 x 7.2 cm Datolite Romero particularly prized these datolites, which before the discovery of (somewhat different styled) crystals from Dalnegorsk, were surely the worlds best of species. Even still today, they have amazing symmetry and geometry that are not often equaled. He had 3 in the collection. This is the largest of them, the only cabinet sized specimen. It is a complete mound of geometric, translucent, seafoam-green crystals of datolite, measuring to about 2 inches across. For crystallography, these old datolites really are highly desirable, but so seldom seen. In great condition, and with a nice accent of pyrite! An elegant example of this species, from a locale that most folks simple have never seen one from. This specimen from the Dr Miguel Romero collection was on loan exhibition to the University of Arizona Museum for over a decade, until my purchase of this collection in 2008. It was on display in special cases at the museum. Comes with custom lucite base already made for the specimen. Mineral
