Turquoise is a soft, opaque gemstone that takes a good polish. The blue color comes from the presence of copper; green tones are provided by iron traces. 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.
