This is a vintage Native American owl brooch. It is not signed but appears to be Zuni. It did test positive as being sterling silver. The brooch has turquoise, black onyx, mother of pearl and shell inlay. The brooch measures 1-1/4 inches long and 1/2 of an inch wide. The brooch is in good condition with no missing inlay. It does have an age patina and may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
