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 Seaham England. 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.
