Absolutely beautifully finished ring, soild sterling silver with a 14kt overlay makes this piece very versatile. The coin itself is made from the silver bars recovered from the Atocha & comes with a certificate stating that. Must see in person to appreciate. You will not be disappointed. I also sign my name on the inside of this piece so you are getting an original Jack Spirit Design & I’d copyrighted.
