Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Monteregie, Quebec, Canada
Miniature, 4.5 x 3.5 x 2.5 cm
Carletonite is one of the very rare mineral species unique to the Poudrette Quarry at Mt. St-Hilaire, Quebec. This is a very colorful, rich, 3-dimensional specimen with rich royal blue color, and an 8 mm, blocky crystal on top. There is a fragment of a 2.0 cm crystal on the side. These came out in the late 1990s. A very respectable, larger specimen from this unique find.
