I love spinel. The GIA reserach compares two purple gem spinel samples with regard to trace element chemistry and visible light absorption spectra, and presents the first reported example of a spinel with a saturated purple color caused predominantly by chromium and cobalt. The GIA research findings are a must read for gemologists, colored gemstone traders, jewelers, collectors, and consumers.
