This is an attractive and decorative antique 18ct gold opal and moonstone gemstone brooch. The brooch is 63mm in length and houses a central, oval shaped moonstone gemstone of size 9.0mm x 6.0mm. This is of excellent quality and exhibits 'flashes of blue' under interchangeable light intensities. It is flanked by 2 oval shaped opal gemstones, each of size 5.0mm x 3.5mm. All of the gemstones are collet-set into the brooch and exposed to its reverse side. There is an '18ct' gold stamp mark on the side of the brooch which equates to its high gold purity. The pin closes perfectly when attached to a garment. The brooch is in excellent condition throughout with genuine gemstones and without repair.
