Green presents the most choices in colored stones, though many of the finest green gems -- such as emerald, jade, and demantoid and tsavorite garnet -- are quite rare and expensive. Green hues are mainly due to traces of chromium and vanadium or iron.
Green gems range in color from the bluish-green of emerald to the chrome green of tsavorite garnet and chrome tourmaine to the apple-green of peridot and the yellowish-green of sphene and chrysoberyl.
Here is a brief tour through the world of green gemstones, including some rare and less familiar gems. Click on a gem photo to view our collection in that variety.
We can set any of our fine Green Gemstones in a custom ring or pendant.
