Vintage Van Dell Glass Opal Gold Filled Brooch

This small Vintage brooch is marked Van Dell, 1/20 12K G.F. It is gold filled. A beautiful faux opal in fiery orange in a gold flower setting with 8 pronged rhinestones on the tips of the flower. The clasp holds well. There is an option to add a chain so that it can be worn as a necklace. No missing stones. I have not cleaned this piece. Non smoking home.
