Rhodochrosite is one of my favorite stones, it is rare and expensive and these particular stones are some of the best quality I have come across, I have had them for along time, and been hoarding them. The beads are wire wrapped with tarnish resistant craft wire and accented with gold Vermeil beads. The chain is 4mm gold vermeil from "Inch of Gold" a company that has been in business since 1982. The chain comes with a lifetime guarantee . (see picture included with purchase). It is available in sizes 8-11, please utilize customization for size choice. To determine proper size measure ankle just below ankle bone and add 1/2 inch. Your anklet will arrive in a lovely gift box.
