Bauxite

A gemstone is a piece of mineral crystal in a cut and polished form which can be used to make jewelry. Bauxite is a sedimentary rock which is the world's main source for aluminum. Let's get into the bauxite composition. Bauxite mainly consists of the aluminum gibbsite, boehmite, diaspora, and many ores. Bauxite was discovered in 1821 by a French geologist Pierre Berthier.  We all would have been in great loss and trouble without this amazing bauxite gemstone.
