Gemstones of Quebec

Hessonite Garnet from the Jeffrey  Mine, Asbestos, Quebec

Quebec has been blessed with a diverse and colourful array of gemstones. Mont Saint-Hilaire is host to at least 30 rare and unusual gemstone species, some of which are found nowhere else on earth. A suite of gems occur in the asbestos mines at Asbestos and Black Lake, including grossular garnet in a wide range of colours and the most valuable of all garnets, demantoid. Coloured tourmaline, apatite, hessonite, diopside, vesuvianite and colourless garnet are found in the high-grade metamorphic rocks of the Grenville geologic province. Many other gemstones are known. With diversity like this who needs Brazil!

Unless otherwise noted, this list only includes localities that have produced faceted gems or crystals that could be cut into gems.
