Vintage Gold Tone Pools of Light Drop Earrings Lucite Screw Back

These are really cool vintage, possibly antique screw back earrings. I'm not sure what the stones are made of, I'm guessing lucite. They are a partially opaque creamy white color, not totally transparent, but do allow a beautiful light to shine though.
I'm not sure what the gold tone metal is, it's not magnetic, but it doesn't have any markings on it to indicate, and I haven't tested it.
I believe these may have had another stone in the top setting portion, although it also looks just fine without one, it doesn't look like anything is obviously missing (unless you know what to look for). Some all over tarnishing/chipping on the metal, although it’s not as noticeable unless you get really close, and use wear on the metal, and may be some minor use wear, no major flaws that I can find. Please see images for details.
