The magic of turquoise... it is a beautiful blue/green stone that is found in only a few places on earth: dry and barren regions where acidic, copper-rich groundwater reacts with minerals to create a porous, semitranslucent to opaque compound of hydrated copper and aluminum phosphate. Turquoise comes in a variety of hues and has been highly prized as a gemstone. It has been associated with calming, refreshing, and serenity and is used frequently in Native American jewelry. This necklace is a stunner! It is 20" of sterling and turquoise beads with a 1.5 inch teardrop-shaped turquoise pendant set in sterling silver. The turquoise in this set leans toward a bright blue hue that is pleasing to the eye.
