This is a brooch that appears to be gold wash over brass and set with deep cobalt blue glass rhinestones. It is not marked but I believe it might be Czech. It measures 1-3/4 inches in diameter. The rhinestones are bezel set and have open backs. The brooch is in good condition but does have minor wear to the gold tone, primarily on the back. It may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
