This is a beautiful large (2 inches long, 1.5 inches thick) cobalt blue piece of sea glass with some clear (it looks blue, but you can see the clear when you hold it to the light) and a lot of tiny bubbles in it. Usually, these large cobalt pieces look black because they are so thick, but the clear makes the blue pop even without a light beneath it. It would be an excellent addition to any sea glass collection. The piece is jewelry quality and comes from my personal collection.
