Best Answer

Opals are not truly minerals (because they don't have a crystalline structure), they are in a class called mineraloid. A mineraloid is an amophous, inorganics substance that lacks a crystalline structure, but are mineral in nature. You will find that in many older reference systems, they may well be classed as minerals.
