    I had seen a few rings online but wanted to see them in person. Whilst they had a few ready made rings of gold and moissanite, mostly it was samples made out of sterling silver and cubic zirconia. I felt like the samples couldn't really give me a good feel of what the final product would look like, which was my reason for attending in person to begin with. More moissanite/gold rings in store would improve the experience.

    We found Moi Moi by chance one day when a birthday surprise had to be rescheduled and first met Oz to have a look at my engagement ring for which I knew I wanted a lab grown diamond. Over the course of the year, we ended up going back to Oz to purchase multiple pieces of jewelry for our wedding. Oz has always been so warm, knowledgeable and very patient. Moi Moi is now our jeweler of choice - I wouldn't go anywhere else. Thank you so much Oz. I couldn't recommend you and your team enough!
