    In general, a gem is any mineral that has been cut and polished for ornamental purposes. A few materials commonly referred to as gemstones, such as pearls and amber, are of organic origin, the former being produced by oysters and the latter being comprised of fossilized tree resin. However, some gems are not really gemstones. Rather their origin is organic. This means that they formed from biological processes, whether animal or vegetable. The class of organic gems is small but includes a number of unusual varieties that are important in the gem trade; amber, coral, jet, ivory and pearl.
