This article reviews the gem varieties of beryl, the associations of beryl with granitic rocks, and the particular association of emerald with ultramafic wallrocks affected by volatile-rich fluids.  The article includes an emerald potential map for the province and a general description of areas of gem beryl potential.  There has been little systematic work on transparent gemstones in British Columbia in spite of a number of gem discoveries in the last fifteen years.
