A classic element of art deco jewelry is the circle pin. This example is constructed of platinum, diamonds and natural ocean pearls. The design is simple with triangular details at the four compass points of the pin which have been flanked by matching pearls. The diamonds are brilliant and closely set together to form a continuous band of sparkle. The pin is in excellent shape with the original safety pin-back. There is some slight damage to one of the pearls which can only be seen under 10x magnification.
