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!!
