Mont Saint-Hilaire, Charmarite

Mont Saint-Hilaire is the type locality for this rare carbonate. There are two polytypes that occur at the quarry, most of these are the tapered, striated, hexagonal prisms which are the 2H polymorph. There are also very platy crystals which are the 3T polymorph. Rare and difficult to find excellent crystals!

  • This matrix has a couple of cavities containing both the platy polymorph of charmarite 2H and the tapered, columnar polymorph 3T. Type locality for this unusual mineral. The crystals are all gemmy-amber colour and some are partly covered wit ha black manganese oxide mineral. Excellent specimen from the type locality. Actually, the only locality where it is found.

  • There are several cavities in this matrix that contain well formed crystals of the two polymorphs of charmarite; 3T, the columnar, tapered, hexagonal crystals and 2H the platy polymorph of this mineral. The 3T crystals are the best! Type locality.

  • A vug at one end of this specimen contains a number of short, prismatic charmarite crystals. As well, there are normandite crystal sections embedded in the matrix. Reasonably priced specimen of two rare minerals from the type locality!

  • An extremely good, fully exposed, tapered, hexagonal prism of charmarite exposed at the edge of a vug. The crystal bridges the vug and is light, resinous colour. Really very good and visible, photogenic crystal.
