This very old piece is gorgeous and absolutely unique in design with fabulous look in Stars and Stripes. The pendant is solid sterling silver hallmarked: 925, highlighted with gold washed bands of gemstones. High quality old brooch weighs in at 19.5 grams of solid sterling silver. I just tested these stones - they are genuine diamonds,rubies and sapphires. Measures: 1 5/8" inches. Beautiful Heirloom Brooch!
