…When we came in to order the rings, Michael himself took the time to personally spend about 45 minutes with us, even though we were getting inexpensive gold bands. I know he is a busy guy so that isn’t always possible, but he educated us on aspects of jewelry we hadn’t previously considered. I believe he used to teach gemology at the college level, and it shows. At no point did I feel like I was trying to be “sold to,” or anything like that…

My favorite place to shop.Often just to look it’s all good.
It really is the best jewelry store I have ever encountered.
It is fair , fun, creative, friendly and Michael and his wife Whitney could not be more helpful.
They treat you the same if you spend a little or a lot.

I just moved to Newport Beach, and I needed to get some links taken out of my watch. I called Michael Mosses Jewelers, and they set aside time to not only take the links out, but educate me on diamonds. They provided excellent service to me, and they possess some of the most beautiful diamonds I’ve ever seen. I recommended Michael Mosses Jewelers in Newport Beach CA to anyone looking for diamonds. Staff is inviting, friendly, educated, and provide a great environment.
