6 dolla jewelry

two different sales i think it was a total of $6. i know nothing about costume jewelry but everything in the box is gold and silver. so well worth it! i wouldn't no Bakelite if it bit me in the ass! i haven't looked through it all but there's some marked monet,coro and a pair of the gold earrings are marked Carla 14k the silver earrings are marked sterling and have some really dark black stones? and a 14k bracelet, 3 black hills gold necklaces. looks like all the loose earrings have matches.i am not sure what the big white necklaces is made of, it looks like hard boiled eggs with a bunch of tiny cracks so porcelain? glass? plastic? looks old! there was even more with this lot that i haven't taken pics of yet. there was one small earring marked 14k with a tiny little pearl on it! if its real ?
