It is so beautifully detailed in the heavy engraved areas in the silver. This brooch has the old C type clasp. I believe it to be from the 1880's. This will make a wonderful to your brooch or your Celtic collection. NOTE; there is some enamel loss.
Vintage jewelry will show some signs of age, which is expected from many years of wear. If I see anything out of normal wear, I will always note it. Thank you and have a great day!
