International Sea Glass Association Festival

The International Sea Glass Festival is the premier sea and beach glass event in the country, celebrating the history and beauty of genuine sea and beach glass. With talented artists and jewelers, knowledgeable speakers, the Sea Glass Contest, and an opportunity to connect with fellow sea glass enthusiasts, the annual Sea Glass Festival is always an unforgettable weekend.

The International Sea Glass Festival is held in different locations around the United States. It is an opportunity for our Professional Members to meet other sea and beach glass enthusiasts, for beachcombers to learn from our lecture series, and for ISGA to further its mission to educate the public about real sea and beach glass. Past festivals have been held in Connecticut, Ohio, New Jersey, Delaware, Maryland, Virginia, Massachusetts, Pennsylvania, and California. ISGA typically announces the location of the upcoming festival at the beginning of the year.
