Absolutely! Our founder wears her diamond engagement ring with a moissanite eternity band on the same finger. You cannot tell the difference. In fact, when testing out prototypes for this business, our founder wore a diamond stud earring in her right ear and a matching moissanite stud earring in her left ear for three months. Whenever she asked people which earring they liked better, they were confused - everyone thought the earrings looked like a matched set!
