The factors determining the principles of filling the polyhedrons in spinels with cation components are considered. An attempt is made to explain the variation in the color range of magnesian spinel modified with chromium ions. A hypothesis for two coordination states of chromium (four and six coordination) in the structure of magnesian spinel is put forward and justified.
