Seaglass jewelry by Maine artist Lisa Hall. I have a couple of her pieces, she is a wonderful artist. She either makes pieces from your own collection, hers, or a combination of both. I find them elegant, simple, slightly mysterious and beautiful.
Real vs. artificial sea glass. Great info from the North American Sea Glass Association (copyrighted article). In this photo, genuine sea glass is on the left and artificially tumbled craft glass is on the right.
