Knorringite is a mineral species belonging to the garnet group, and forms a series with the species pyrope. It was discovered in 1968 in the Kao kimberlite pipe in the Butha-Buthe District of Lesotho and is named after Oleg Von Knorring, a professor of mineralogy at the University of Leeds in England.
Synthetic knorringite has the pure endmember formula Mg3Cr2(SiO4)3. As knorringite is a member of the knorringite–pyrope series, natural samples contain variable aluminium in the chromium site. Knorringite is a greenish blue color with a Mohs scale of mineral hardness of six to seven.
