Safety hook in back. Approximately 2 inches in length. Growing up in Europe and Asia, I continued being enthralled with jewelry. I learned to cut gems in South Korea at a lapidary shop when I was twelve and to cast and construct jewelry shortly after that. My formal education was in Art at several universities, finishing with a Masters of Fine Arts in Goldsmithing from SUNY New Paltz in New York. A couple of weeks after I graduated I was in my first craft show, and haven�t stopped yet.
