Emeralds belong to the beryl family of gemstones. This family also contains aquamarine, goshenite, morganite, heliodor, quartz, ruby and red beryl to name a few. The emerald has a hardness of 7.5 to 8 and is composed of chromium and vanadium. When iron sulfate pyrite is entered into the mix the result is the rich green color traditionally associated with the emerald.
