Buying jewelry Lot

Product Name: Buying jewelry Lot
Nice little jewelry lot that I will never wear again. Sorry, it was hard to get pictures without making them blurry but I promise these are very pretty and shiny in person!! All from Greenbergs. None are “real” that I know of. Maybe the necklace because the stone is very small. I honestly know nothing about jewelry and didn't care to ask when I received them. The Infinity necklace has black stones and clear stones. The earrings have never been worn, the infinity necklace was worn a handful of times and the other necklace was worn 2 times. The earrings have markings on the underside but I can't make out what it says. The infinity necklace says 925 on the clasp and the other necklace says 10k on the clasp. Please ask any questions you buying might have!.
