New Signed CH Momex Sparkly Crystal CZ Pendant Necklace Earrings Jewelry Set

The connector on the 17.5" chain is stamped "Momex" & "CH". These 2 stamps are the only ones I'm sure about. There's also what looks like an upside-down triangle & 2 more marks I can't quite make out. But at another angle, it almost resembles "22K". I doubt this is the case because there are no such marks on the earrings & pendant. The 5/8" pendant & 13mm stud earrings have very sparkly pronged stones, which are either crystals or CZ's. In some cases, "CH" stands for Caroline Herrera, but I haven't seen hers together with the "Momex" stamp.
