Necklace Turquoise Rough Nugget with Gold Fill toggle and textured beads

This is turquoise I have been collecting for many years. Each piece is an authentic piece of turquoise from various mines across the United States. There are mines all over the southwest, the Kingman, the Sleeping Beauty, now closed, the Fox mine and Mine 8. Each mine has a signature color, and type of matrix. As a gemologist and a gems expert, I have been collecting these pieces and finally put them on a nice strong white Kevlar cord with an easy to use hammered open toggle and bar, with textured beads to create a professional finish on the design. 18" long this necklace is from my private reserve and very special.
