Artisian Copper And Stone Pin Brooch Large Boho Statement Vintage Costume Large

This is a very large statement brooch made of copper and stone. It can also be a pendant as it has a loop for attaching a chain. 2.5" wide and 3.75" long. This piece does have signs of wear and really needs a good cleaning by someone who knows what they are doing. Not sure what the stones are, one is grayish, one is blue and one is white.
