This is a turquoise brooch that I believe is Native American. The brooch is not signed and I do not know who made it. It tested as being sterling silver but there is no mark. The brooch measures 2 inches by 1-1/4 inches. The turquoise is bezel set. The brooch is in very good condition but does have an age patina and may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
