This sea glass beach bubble was handmade by me from silver metal clay. After the clay is dried and refined it is kiln fired and becomes pure silver. Then I carefully apply several layers of enamel, firing between each layer. The sea glass featured in this pendant was found in San Francisco, California . The sea glass is set in fine and sterling silver. The approximate length of the pendant is 1 3/4 inch and the width is 1 inch. The pendant comes with an 18 inch sterling silver snake chain with a lobster clasp.
