The Messina Mine is home to these unique, and beautiful, Quartz crystals included by the rare copper silicate, Ajoite. The first generation of Quartz is richly coated by the Ajoite, and the second generation Quartz then preserves it as a wonderful turquoise-blue phantom within. And, these are doubly-terninated, no less. Rarely will you find one of these combination pieces in such good, aesthetic, quality; AND in a thumbnail size!
