Optical absorption spectroscopy and X-ray structural refinements were used to characterize short-range and long-range structures of 10 gem-quality, blue spinel single crystals synthesized on the (Mg 1-x Co x ) Al 2 O 4 solid solution (x = 0.07-1.00). The site distributions of Mg, Co 2+ , and Al show
