As the name provides, genuine SEA GLASS is born out of the sea. While BEACH GLASS is found on non-marine beaches. The Great Lakes have produced some of the most beautiful beach glass I've ever seen. So if you don't live near the ocean, fear not. These frosted little gems can be found wherever the natural aquatic elements meet a piece of glass (provided there is enough time to round the edges).
