The listing, Royal Crown Brooch with rhinestones an opaque stones has ended.
2 inch Royal Crown brooch with paste set rhinestones and two good sized oval opaque white stones at the top. I have not clue as to age. The metal appears to have been treated to give the crown an antique appearance, but it maybe that it just needs a gentle cleaning and polish. I've not tried to clean it. I couldn't find any markings on the back. The clasp works well. There are no missing stones.
