This is a 4" Sterling of Flowers Brooch / Pin. Two of the leaves, part of the Ribbon and Rosette Button on the ribbon is Gold Plated over the Sterling. The rest of the brooch is Sterling. The only repair that needs to be done is replacing the pin that is missing on the back. On the back of the brooch, it is marked "Sterling" on a small attached tab.
