Garnet is a rather complex mineral that has a general chemical formula of R 3 R 2 (SiO 4) 3, where R 3 is a bivalent (gives up two electrons) metal and R 2 is a trivalent (gives up three electrons) metal when forming a chemical bond. The metal R 3 may be(Ca )

Garnet Garnet is a more complex orthosilicate (than olivine, for example) in which the SiO 4 tetrahedra are still independent. Garnets have the general chemical formula A 3 B 2 Si 3 O 12, where A is a divalent cation (Fe 2+, Ca 2+, Mg 2+, Mn 2+) and B is a trivalent cation (Fe 3+, Al 3+, Cr 3+).
