This is actually a personal item of mine that has been passed on to me from the family. I know that the diamonds are real and not simulated. Unsure of the total carats. I know that it is antique with the antique hallmark. Lion stamp and my father an antique dealer before he passed. fits the size 7 but can be sized. The safety on it currently is not gold, but I just had it because my fingers fluctuate size. Just gorgeous❣️ make an offer
