The Hunter Lab’s latest work on the origin of the red color in tourmaline gemstones was featured on the cover of Inorganic Chemistry. The cover features tourmalines from the Blue Cap Pocket of the Tourmaline Queen Mine, Pala, California. The zones of red coloration are due to oxidation of Mn2+ to Mn3+ by natural irradiation by gamma rays. The underlying cause of the red color has been subject to debate. In the article, the researchers provide new spectral assignments which illustrate the importance of spin–spin coupling in mineralogical samples. Photo Credit: Erika & Harold Van Pelt.
