Petarasite Locality: Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada (Locality at mindat.org) Size: 4.0 x 2.9 x 2.7 cm. An incredibly large, sharp crystal of this very rare species found in only a few small pockets over all the years at Mont Saint-Hilaire. It was in fact self-collected by the incredibly persistent collecting couple, Marcelle and Charles Weber, and remained in their collection since 1980. At approx 1.5 x 1 cm, this is large for the species. Moreover, it displays really nicely atop contrasting matrix. It has a lustrous, red-brown color to it. It is terminated on the left end, contacted on the right. Mineral

Petedunnite Locality: Franklin, Franklin Mining District, Sussex County, New Jersey, USA Dimensions: 8 cm x 7 cm x 3.5 cm; weight: 225 g Gift of John Cianciulli (June 2000). MOB coll. The petedunnite is the dark green stuff on top. It looks much like any other dark green pyroxene to me so I don't think it would be possible to ID the stuff visually. Presumably John had good provenance on this specimen. According to Dunn's Franklin/Sterling Hill monograph, petedunnite has one poor cleavage on {110}. In this specimen, cleavage (or parting) seems evident from a distance but appears very indistinct under a scope. (This is from the Buckwheat Dump but I don't know if it has been established that petedunnite is actually from the Buckwheat pit. Hence I posted under the more generic "Franklin Mine".) Mineral
