American Mined™ Sleeping Beauty Turquoise Round Cabochon, choose your size

Mined from the mountains of Arizona, this round American Mined™ Sleeping Beauty turquoise cabochon offers a classic sky blue with minimal matrix that is great for your gold and silver jewelry designs. Sleeping Beauty turquoise has been enhanced using electrochemical treatments to make the color permanent. The Sleeping Beauty mine closed in 2012, making this material valuable and increasingly rare. 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.
