Mount Saint Hilaire, Quebec, Canada

This small specimen consists of a single, incomplete Kupletskite crystal. Though it is incomplete, it is undamaged and in excellent condition. The crystal itself makes up most of the dimensions of the specimen. Its triclinic, bladed form is rather poor, as only a few crystalline edges are visible, and all faces are incomplete due to growth inconsistencies. It has a dark brown coloration with paler, red-brown highlights and a dull pearly luster, and is essentially opaque. It is accompanied by a few incomplete bladed crystals that I cannot identify, and the piece is hot-glued onto a flat, square acrylic base.

This thumbnail specimen contains numerous crystals, most noteably brown, transparent crystals of kupletskite. The largest kupletskite is adjacent to the largest aegirine crystal. There are more of each, although most of the easily visible crystals are aegirine. The host rock is an assemblage of tiny black aegirine and brown kupletskite crystals in a matrix that is mostly albite and quartz, although there are other minerals present, as well, including something pink.
