Description

An American Mined™ gemstone, BlueBird Turquoise™, mined in Kingman, Arizona, displays a vivid robin's egg blue color with minimal matrix. What matrix is present tends to be fine and varies from light to dark gray color, making each stone unique and ideal for custom designs. Turquoise is one of the birthstones for December.

Turquoise is a soft, opaque gemstone that takes a good polish. The color of this variety comes from the presence of copper. Natural turquoise is untreated, chemically or otherwise. Treatments for turquoise include electrochemical enhancement to improve color and stabilization with resin that darken and harden stone. Individual types of turquoise are usually named according to their source.
