This is a vintage Mexican sterling silver and abalone butterfly brooch. It is marked STERLING 925 and has the Eagle 12 mark. The brooch measures 2 inches by 1-3/4 inches and weighs 5.2 grams. It is in good condition but there is wear to the silver on the back of the tip of one wing. It cannot be seen from the front and is only noticeable if you are looking for it. The brooch also has a heavy age patina and may need cleaning or 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. The buyer is responsible for shipping and handling costs and I am happy to combine costs for multiple purchases. Please let me know if you have any questions. Thanks for stopping by.
