Ornate Multitiered Dangle Regency Pendant Brooch Necklace with Onyx in Gold Tone

Ornate Multitiered Dangle Regency Pendant Brooch Necklace with Onyx in Gold Tone. The brooch portion is stupendous, with swoops and screens, and chains, and curlicues, and wings and arches, all leasing down to an oval onyx cabochon. The necklace chain is not in the same style as the pendant, I do not believe it is original. The necklace chain is 18 inches long. The drop of the pendant brooch is 5.5 inches long. It is just longer than choker length. The pendant/brooch will lay on the upper chest. I bought this from the owner of a defunct jewelry store. She said it is not vintage. Goth Victorian Regency Edwardian Festival Cosplay NWOT. In excellent condition with no noted signs of wear. Please see photos for condition details. Thanks!
