Natural Garnet/Natural Emery is a very hard rock type used to make abrasive powder, which is brownish-black or dark gray in color. It is the hardest mineral after diamond, making it the second hardest mineral with a mohs hardness value of 9.
Natural Garnet/Natural Emery largely consists of the mineral corundum (aluminum oxide), mixed with other species such as the iron-bearing spinels hercynite and magnetite, and also rutile (titania).
The kind of Crushed or naturally eroded emery (known as black sand) is used as an abrasive, for example, on an emery board, as a traction enhancer in asphalt and tarmac mixtures, or as used in mechanical engineering as Emery cloth.
