  • Garnet - Wikipedia

    en.wikipedia.org/wiki/Schorlomite Knorringite is a magnesium-chromium garnet species with the formula Mg 3 Cr 2 (SiO 4) 3. Pure endmember knorringite never occurs in nature. Pyrope rich in the knorringite component is only formed under high pressure and is often found in kimberlites. It is used as an indicator mineral in the search for diamonds. Garnet structural group
