Yes, you are seeing that correctly, it’s safety glass! Perfectly smoothed by mother nature and a little rust from the exposed metal. If you’re looking to strike up a conversation with people, this piece will absolutely accomplish that! It has a crack through it on the lower left side, but it isn’t going anywhere, the metal is keeping it right in place. Measuring 1 1/2″ wide by 3/4″ tall, it would go with any type of chain, from Sterling Silver to any color leather.
