Silver and black dangling earrings- made by VA artist

I think the oval piece of these is maybe silver plated but not 100% sure. They came from a gift shop n SW Virginia, and have black sparkly stones hanging at the bottom. They are roughly 3/4” x 1.5” each. I might have worn them once, but usually give up after 5 mins due to nickel allergy. I’m giving up for good, finally, on jewelry… period. I am listing my life on here the next few weeks… check back!!
