This unique hippo cuff bracelet is made of sterling silver. An artist was able to capture a group of watering hippos with breathtaking detail and great craftsmanship. Bracelet is 1 inch wide at the center. It will fit a small size wrist (bracelet's inside circumference is 6.25 inches). Opening is 0.75 inch wide. Bracelet is unmarked, but it has been tested and it is guaranteed to be made of sterling silver.
