f I had to give a rating, it would be 11 out of 10. The pieces are beautiful and flawlessly crafted. The company is highly professional and truly respects and understands the customers. The prices are fair, and you won't find this level of quality at a lower price anywhere else. I am very satisfied and happy with my choice.

Had an amazing experience ordering my dream ring through 18Karats. It was a custom order, which they accommodated without any problems. They explained what options I had, what kind of settings would fit my idea and what type of diamonds to choose from. The ring came out perfectly and just as we discussed (and in the matter of few days). I can’t recommend them enough!!
