Handmade butterfly pottery necklace - unique design and comfortable to wear. Very lightweight. Cord: Black silky nylon, approximately 18 inches long, features a lobster clasp. The back of the pendant has been intentionally left unglazed, so you can add a drop of essential oil if you like. The pendant is cut out of clay, fired in a kiln, and then glaze is applied and designs hand-painted. The pendant is then fired again in a kiln. Please note, care must be taken not to drop onto a hard surface. It is recommended to cover your sink/countertop with a towel, just in case, while putting on your pendant. Metals: Mixed (stainless steel, iron, brass, sterling silver plated)
