This is a natural stone polished to a high luster and wrapped with quality wire. All of our stones are secure in their setting and I promise people will stop you in the street to ask where you got it (be sure to point them my way!). There are only three components to each stone (the rock and the wire...and lots of love and appreciation for the beauty of nature). This gemstone is natural and has not been treated. The pendant measures 2-1/8 inches by 1-1/4 inches. It is wrapped with 14 karat gold filled wire and weighs 16.5 grams.
