This sterling necklace has a beautiful brown piece of Maine sea pottery that I found along the coast. The center piece is a textured piece of brown sea glass and the bottom Freshwater Pearl . The pendant itself is approximately 2 1/4 inches long by 1 1/4 inches wide. It is on a 18 inch box chain. Other chain lengths are available upon request, just send me a convo. I carry 16,18 and 20inch chains. This is a one of a kind piece.
