MOLDAVITE:

Chemistry: Varies but is mostly silica glass with impurities of magnesium, iron and other elements.

Class: Mineraloids

Uses: As a gemstone and as collection specimens

The members of the (unofficial) Mineraloids Class are often mistaken for minerals and are sometimes classified as minerals, but lack the necessary crystalline structure to be truly classified as such. Pearl, jet and amber are in addition the products of organic process that further remove them from full mineral status. These materials are found naturally, some are treated as gemstones and are included in most mineral references (which is why we decided to include them here!).
