This antique Art Deco cloak closure would have had the end glass stones slip between button holes on a cloak or fur wrap. the faceted yellow glass stones measure 15mm. A few prongs look like they could be pushed down but the stones are secure nevertheless. The brass has a good patina but you could polish if you wish. Shipping is free!
