5.2" Colorful Iris Blue CARLETONITE on Matrix-Mont Saint-Hilaire Quebec for sale
Availability: In Stock
This attractive specimen of CARLETONITE comes out of the Poudrette Quarry in Mont Saint-Hilaire, Rouville RCM, Monteregie, Quebec, Canada. This is the only known locality for this very rare silicate mineral. The mineral carletonite is found in marble xenoliths, typically as crystalline cleavage masses in white marble; only a handful of euhedral crystals have been found. This is a colorful specimen with good cleavages in a desirable cornflower blue. Carletonite specimens of this size and quality have always been rare, and now that the quarry is closed to collecting, no more are likely to emerge. I picked out this piece at the Tucson Gem Rock and Mineral Show in the room of a mineral dealer from Quebec whom we have dealt with for years (he got it from an old collection).
In late 2007 the Poudrette quarry was sold by the Poudrette family, and is now called Carrière Mont Saint-Hilaire. The new owners do not allow any collecting, though there were 2 field field trips (in Oct. 2008 and in Oct. 2010), under very strict rules. Today, all the rock from this quarry goes through the crushers. Future collecting here is uncertain, and highly unlikely.
