There is no absolutely valid classification of all gemstones because the term "precious / gemmy" is not clearly definable. To create a useful system for this website I subdivide the here mentioned, worthy for cutting, and demanded minerals into commonly known minerals, rarer (so called collector stones), very rare (rarities) minerals, extremely rare (world rarities), and relatively rare organic material.
