This is an antique bar brooch, which is made of 15 carat gold and is set with 4 natural pearls. The pearls have a diameter of 3mm, and the brooch is 5.5cm long. The back is stamped 15Ct, which was a gold standard in Victorian times. The old-fashioned catch would underpin this dating. The brooch weighs 3.14 grams, and everything is in excellent condition.
