It's a one inch square solid sterling silver on the back, which allows for lots of custom engraving space. The cross is also sterling silver. The two pieces are textured with different hammers, to create a bold contrast. I add a dark antique patina to highlight the rustic style. It's great for a man or a woman who likes the rustic look.
