Sterling silver and black druzy agate hat pin. This pin measures 1.625 inches high X 1.25 inches wide and can be used as a tie tack or lapel pin. The agate was cut to show off the druzy crater in the center of the stone. After choosing the stone, I used an assortment of old hand tools, silver stamps and torch to create the piece. I then used various polishing compounds to get the final shine. The pin pictured is the one you will receive.
