This is a sterling silver and a unusual shell called Lion’s Paw is an off-set design by world renowned artisan Jimmy Calabaza. It weighs. It weighs over 2 oz of SS with stone and bail. All of Calabazas pieces are marked with the Calabazas native american name Ca’ Win which means freedom in Keva and also is the Santa Domingo Pueblo name. This is a sensational piece with Calabazas sterling silver and choice of different gems, so unusual. The opening measures 1 1/2″, widest (inside) 2 1/4′. As is, it would be considered a small, but, the way the lion’s paw is offset on the silver, it could be for a medium or large wrist. BUT, IT MUST BE DONE BY A QUALIFIED JEWELRY. He is world renown and can be seen in many galleries including the Smithsonian.
