We have 4 sets of Jacmel Mauritius 10k gold earrings. The standout is, of course, the tricolor diamond cut pair but the other three are wonderful as well. Each one of the CZ stud sets are incrementally different in size. Only one set of the CZ stud earrings don't have backs. I found the other back to the one set that shows only one back. In conclusion, only one set of the CZ stud earrings don't have backs. Phew!  Very simple, very beautiful.
