This piece is so unusual it is hard to know how to describe it. The piece is unsigned but tests sterling. The large pendant is 2 1/4" North to South and the chain is 28". It is a continuous chain that you slip on over your head.
The entire piece weighs over 28 grams. There are no hallmarks, it looks very Danish to me.
I have not polished it in fact I think even polished it will have the antiqued area inside around the stone.
