This is a typical mid-Victorian large brooch. The ribbon-tied shape is called a "lover's knot," representing eternal, unbreakable love. There is a locket on the back, but I don't know how to open it, so I haven't opened it. There are signs of repair on the stones, and it's possible that only one stone was replaced. Garnets of a rare color, like amethyst, are used, and it seems that this color of garnet was often used in Victorian times. The stone setting is also typical of the Victorian era. I imagine the handwork was very difficult. The matte gold has a luxurious feel. It must have been a brooch for nobility. It weighs 26 grams. It's over 100 years old, but it can still be used. The material is unknown, but personally, I think it's beautiful gold. Please understand that this is an antique item.
