Set of 2 pair of stud fashion earrings, NWOT, black druzy style & cubic zirconia

Fashion Costume Jewelry Set of 2 pairs of stud earrings. Pair 1- Black druzy style. Subtle, but pretty shimmer in the light. Set in a silver backing. Pair 2 - Clear, cubic zirconia, very pretty classic style. Set in claw style holdings. Both pairs have silver stud backings. Brand new, never worn. I have too many and need to downsize my collection. No flaws that I can see. As they are fashion earrings, I cannot guarantee that these are not hypoallergenic. Please see pics for approx dimensions.
