Bauxite

Bauxite is an impure mineral that contains hydrous aluminum oxides and aluminum hydroxides. In 1821, the first commercial source of bauxite was a mine near Les Baux, France; since then deposits have been found worldwide. Bauxite ores are usually a mottled reddish brown but can also be white, gray, yellow, or red. They typically contain 3075%

Gemstone Cleavage Chart

 · Cleavage is graded as perfect, good, indistinct or "none" (in the case where a gemstone has no cleavage at all). The following chart lists the cleavage ratings for many well known gemstones. You'll note that different members of the same species or family, such as quartz or beryl, have the same cleavage. That's because members of the same species have the same crystal structure.
