I have encased the Turquoise beads with Argentum Silver. Besides using Turquoise beads, I also added Chrysacola, turquoise glass and chip beads along with black agates. The clasp is stainless steel. It will not tarnish.
"Turquoise is one of the oldest protection amulets, and was also known as a symbol of wealth in many ancient cultures."
"Historically, Turquoise is credited with the property of securing friendly regard, verifying the traditional saying that “he, or she, who owns a Turquoise will never want for a friend.” [Fernie, 37] In the Orient, a Turquoise ring was worn as a protector against all things evil. The proverb states: “Given by a loving hand it brings with it happiness and good fortune.” " It was believed to restore clear vision to the mind when the thinking became muddled and thus ensured good fortune. [Mella, 111] "
