Sterling Silver hand crafted Ring. There is a large Bump in the back of the ring to prevent sliding,and makes it hard to size. so I have to guess the ring is approx a size 7. The stone in the ring is an agate, or i think Obsidian, ansd is a very dark grey color. It is 2 inches along the finger and 1 inch wide. It looks great on, and because of the bump in the back it does not 'swing' on the finger.
