1960s Geometric Cut Out Brooch with Gemstones

This unsigned beauty of a brooch is from the mid 1970s and formed of five gold geometric shaped frames - a square, a rectangle, a triangle, a circle and a hexagon. Each is detailed with a different coloured gemstone in pink, green, blue, smokey grey and turquoise. The rear of the brooch shows the intricate work and we can't believe that something so well designed does not have a maker's nark. It is finished with a long bar which closes with a C-clasp. In very good to excellent vintage condition with no issues. MEASUREMENTS LENGTH - 1.6 in. (4 cm) WIDTH - 2 in. (5 cm)
