Mexican Turquoise

It has been reported that new production of turquoise from a large open-pit copper mine, about 110 km south of the U.S border from Douglas, Arizona is the new source. The Nacozari turquoise is found in nodules; though chalky much of the material is hard enough with good color. The rough pieces show inclusions of pyrite, quartz, and mica. Most materials are fashioned as cabochon or free form. The materials may be stabilized to improve color.
