This is a vintage brooch I believe is Native American. It is not marked but appears to be sand cast silver. The brooch has designs stamped along the edge and in the center. The very edge of the brooch has a scalloped design. The brooch has a C clasp. It measures 2 inches by 1-3/8 inches and weighs 10.9 grams. It is in very good condition but does have a slight age patina and may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
