I found this in a lot of Navajo and Hopi sterling. The green turquoise main stone is swirled with natural copper matrix (not reconstituted). Pay close attention to the mounting of the 2.5 carat (est) peridot, as it is slightly off center. All metal is 925, and the piece has a substantial feel. It has drawn constant compliments when I’ve worn it. You will be ecstatic when it arrives.
