This ring is brass with rhodium plating to give it a brighter look and to make it much more durable than sterling. Front legs are stationary, but back legs move up and down. Frog is 1/2 inch long and slightly bigger than that in width. This is a cute conversation piece for frog lovers and a fun ring to wear. A good size for any age group. In rhodium plated brass it is part of our Look of Silver collection.
