American Mined™ Arizona Turquoise Oval Cabochon

With the Sleeping Beauty mine long closed and authentic rough increasingly difficult to source—this American Mined™ Arizona turquoise cabochon, mined in nearby Arizona regions, offers the same classic sky-blue hue and minimal matrix that pairs perfectly with warm gold or cool silver tones. Arizona turquoise has been enhanced using electrochemical treatments to make the color permanent. Turquoise is one of the birthstones for December. Turquoise is a soft, opaque gemstone that takes a good polish. Its sky blue color comes from the presence of copper; green tones are provided by iron traces. Turquoise sometimes has a rock matrix and varying shades of gray, brown or black veining due to inclusions or oxide stains. Rio is proud to offer the American Mined™ Collection, a growing selection of gemstones sourced from mines located here in America. These gemstones consistently present the excellent color, clarity and quality we look for in every gem we offer you.
