I am a professional beachcomber and have been making sea glass jewelry for a living for over twenty years. While living in the Caribbean I collected hundreds of sea glass marbles and they are my most cherished treasures in my sea glass collection. My sea glass jewelry can be viewed here - http://www.naturalseaglass.com/and I also host a social networking site that can be viewed here - http://seaglassartists.ning.com/ I am also a board member of the North American Sea Glass Association.
