This pretty stone is appropriately called Wonderstone. It was cut by master stone cutter Gary Wilson of Arizona. I set it in sterling silver and hung it on a braided leather cord. It can be removed and hung on other necklaces for a variety of looks. The pendant including bail is 3.75 inches long and the necklace is adjustable from 17.5-19 inches. Only one available. Complimentary polishing cloth included.
