Opal, being amorphous, is not really a mineral but a mineraloid. One of the scientifically accepted standards defining a mineral is that a mineral must have a crystal structure, which opal lacks.

For this reason, Opal -- as well as other amorphous types that fall under the definition of a mineraloid.
