Vintage Blue Agate Brooch/Pendant

Stunning vintage brooch or pendant with a blue agate stone in the middle. It has a pin on the back so you can use it as a brooch and a loop on the top so you can use it as a pendant. We think it is made of real silver, but are not 100% sure since there is no stamp on it. In very good vintage condition. 

Please take a look at the pictures, as they are a part of the description.
