This is a very large sterling cross and an adjustable sterling ring. They both have a very good feel and very stylish. The cross is almost 4 inches high and the ring is just under a quarter around with an adjustable shank. It is marked also but I could not read it.. The green insert in the cross and the ring is very interesting. It looks like a striped bakelite. Both the ring and cross is marked but I could not read it. You will need a lovely sturdy chain for this fine cross. If you know what it is please let me know. From Kansas.
