Are all gems minerals? A mineral is an inorganic, naturally occurring substance with distinct chemistry and crystalline structure. Gemstones are materials that have an economic or aesthetic value. Therefore, not all gemstones are minerals. For example, amber is solidified tree resin, so it is not a mineral. Gemstones can be classified as either amorphous or crystalline. Amorphous gemstones have no orderly internal atomic structure and no naturally occurring shape. Glass, amber, and opal are examples. Crystalline gemstones are minerals; they have a definite and regular internal atomic structure. Examples include garnet, emerald, and ruby.
