Cute vtg black & white heart jewelry set

Cute! Matching necklace and earring set of quirky black and white enameled hearts with goldtone trim. The necklace also has black and white beads. It's about 16" total length, so probably a choker on most of us. The earrings are clip ons. The part of the earrings that touched the green velvet backing on the store packaging was tinged green. I cleaned them (gently, with soap), but the green didn't come off. I did remove the green velvet, it is only shown in that one photo so you can see what I'm talking about. Back of one earring has a dark discolored spot that also didn't come off when cleaned. Otherwise excellent condition!
