The petroglyph design on this extraordinary cuff bracelet are numerous and finely detailed with images that include sun, stars, hands, spirals, among many others.  The piece is tufa cast, meaning the design is carved out of a soft volcanic rock called tufa making a cast.  The molten sterling silver is poured into the mold and hardens as it cools and is the broken open and you have an incredible piece of art.  It was hand made by Antone Honani from Hopi Pueblo.  It measures approximately 1 3/4" across the top.  It should fit most wrists.
