A group of iron aluminum silicate homogeneous minerals having similar properties. non-hydroscopic, sharp angular shape, inert, slightly magnetic, not soluble in water, translucent, friable to tough, and contains no free chemicals. All oxides and dioxides are combined chemically as follows: Fe2O3Al2(SiO4)3. The iron and aluminum are partially replaceable by calcium, magnesium and manganese.There are three types- aluminum garnet, iron garnet & chromium garnet.
