Vintage gold tone and purple jewelry set

Beautiful vintage gold tone and purple jewelry set. There is a makers mark in all 3 pieces, marked C*C, but I can't find any information on this designer what so ever. The set is the necklace, bracelet and earrings. The necklace is 23 inches long, the bracelet is a standard 7 inch bracelet and the pierced earrings are just under 2 inches long. In excellent condition!
