This sterling sailboat necklace has a piece of lavender sea pottery from the coast of Maine and a piece of lavender sea glass. The bottom has a white freshwater pearl. The pendant itself is approximately 1 1/2 inches long by 1 1/2 inches wide. It is on a 18 inch rolo chain. Other chain lengths are available upon request, just send me a convo. I carry 16,18 and 20 inch chains. This is a one of a kind piece.
