Carletonite on Matrix | 88.8 grams | Mont-Saint-Hilaire, Québec, Canada | SO24

Carletonite is a rare and visually delicate mineral best known for its soft blue color, though it may also appear in pink, white, or colorless forms. It crystallizes in the tetragonal system and has a Mohs hardness of 4 to 4.5, which makes it too soft for most jewelry applications but highly prized by collectors. It displays a vitreous luster and is usually transparent to translucent.

Carletonite was first discovered in the Mont-Saint-Hilaire alkaline complex in Quebec, Canada, which remains the only location where well-formed, high-quality specimens have been found. The mineral was named in honor of Carleton University in Ottawa. Although Mont-Saint-Hilaire is the only confirmed and significant source, there have been occasional reports of possible carletonite occurrences in Russia and the United States. These findings are extremely limited and typically lack the clarity and crystal quality seen in the Canadian material.
