this is a pair of open backed, coloured glass stones, vintage clip earrings on white metal. The earrings are in a cluster shape. There are five open backed coloured stones that are 'see through' (i.e. have no backing on the stones) - in green blue, yellow, red, mauve. The central stone - which is not open backed - is light blue. The outer stones have an elaborate curved claw setting. There are eight smaller stones which are on stalks. These, and the central stone, have ordinary claw settings. The condition is good and the clips are firm. The diameter is about 1 1/4 inches. The reference is 3315.
