Very hard to find deep teal sea glass found by Christeena Hockin-Minopetros owner of Sea Glass Jewels & Co. in Greece. The color of the pieces are amazing. The workmanship is top of the line. She was always one of the favorite vendors at the sea glass festivals. I have put this on a thick 925 chain. I bought many pieces from her. She was very knowledgeable, friendly and I always looked forward to spending time with her. I have only worn this a very few times.
