This is a vintage cameo marked Coro with both the Pegasus and Coro marks. I believe it is gold filled. The brooch is made in Victorian Revival style. It measures 1-1/8 inches wide and 1-1/4 inches tall. The brooch is in very good condition with no problems that I can find other than it may need polishing. I offer a 7-day money back guarantee. All methods of payment are accepted, however, checks must clear before shipping. Credit cards are accepted through PayPal. Please let me know if you have any questions. Thanks for stopping by.
