These three pieces are made out of what I think are called "sea beans". A kind of a nut or seed that has been polished. Hard to research this set. There is a necklace, matching earrings and a cross pin. The necklace measures 18 inches, cross measures 3 inches and the earrings are 1 1/2 inched. I will date this to late Victorian. Metal is rose gold fill. If you are going to wear the earrings I will give you new rose gold filled earring wires as these look very old and delicate to me. Color is a rich warm brown. Each bean or nut is about 15mm in size.
