The Mineraloids

Mineraloids is the term used for those substances that do not fit neatly into any of the eight classes of minerals. Opal, jet, amber, and mother of pearl all belong to the unofficial class called mineraloids. They are created from organic compounds or lack crystalline structure that would qualify them to be real minerals.
