Will recommend to anyone who will listen

The whole process was easy and painless in what could be a very stressful purchase. I was very wary of buying jewelry this expensive on an online jewelers, but my soon to be fiancée found the exact ring she wanted on your website. Not for one instance did I see a red flag and the customer service/communication was so reassuring, friendly, and helpful. I have nothing but good will towards Oui.

Everything about this experience felt personal! We were skeptical at first about creating a ring online but Oui made everything extremely convenient. My fiancé and I designed my ring together which was very important to us. Everything about this ring is perfect. The craftsmanship is incredible and I get compliments ALL the time about how gorgeous the setting is. 10/10 all around!

The Jean Dousset team completely outdid themselves!!

From the very beginning of designing my upgrade ring to receiving it in the mail, it was 5 star service. From quick responses, video chats, communication throughout the building of the ring I cannot say enough good things! And to top it off, the ring is absolutely stunning!
