ChicSilver Silver Necklace & unbranded stud earrings with Green CZ peridot color

** These were purchased separately and the shade of green is slightly different on the necklace vs. the earrings. Silver necklace with olive green cubic zirconia. It's from Chicsilver brand from Amazon, retail was $25 and was sold as sterling silver. It has never tarnished so I don't know what the material is. It has an adjustable chain. It's listed by the Amazon seller as Peridot but looks more olive green in real life versus peridot. The 925 stamp is on the tag at the clasp, see pic. I wore it a few times and cleaned it with silver jewelry dip. Silvertone stud earrings with green cubic zirconia stones. the 925 stamp is on the posts but it's too small to get a picture of. They haven't tarnished so I don't know for sure what the material is. These were originally from Aliexpress. the backings are the original the earrings came with. Aliexpress listed them as "natural stone" but I don't know for sure if they are. I wore them a few times and cleaned them with silver jewelry dip. There's no flaws I just have way too much jewelry.
