Huge Gorgeous Yellow Helmet Seashell for sale, "Cassis cornuta," also called Horned Helmet Shell, a large heavy peach colored shell, faintly marked with whites and browns. This gorgeous Yellow Helmet Shell measures approximately 11-1/8 inches tall and 7-1/2 inches wide.  Carefully review all photos. This is the one you are buying. It was hand selected out of our large inventory.  Would make a nice addition to a shell collection.  These large seashells live mostly in warm waters around the world.   This is a beautiful real cassis cornuta shell - not a replica.  It will have some imperfections from living in the oceans and aging.
