Each necklace is made to order with a genuine surf tumbled piece of cobalt blue sea glass. The frosted cobalt blue sea glass is wire wrapped and hung on your choice of either a real leather cord necklace or a sterling silver box chain. The frosted cobalt blue sea glass has a great shape and a smooth flat surface. The frosted cobalt blue sea glass is authentic frosted beach glass collected on the rocky shores and sandy beaches of Casco Bay, in coastal Maine and coastal New England. The sea glass has a lovely natural frosted surface as a result of the glass being tossed about the waves and ocean shores for many years. The necklace is handmade; the sea glass was carefully selected for both it's shape and wonderful color. The necklace comes from a smoke free environment and is made in the USA. Please note: Because the sea glass is genuine / authentic / real the necklaces are all different and unique. Please look through all photos to get a sense of what yours will look like. While the sea glass is selected due to their similar shape, color and texture there are some differences, each necklace is unique and no two necklaces are the same. The measurements are approximations. The sea glass measures approximately: 26 mm x 22 mm x 7 mm or 1.06 inches x .85 inches x .29 inches SKU# 11392
