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.
