Really nice & different ring, especially for the price. Wasn't sure how sparkly the stones would be because of the unusual setting, but they are quite sparkly and I don't think the average person could tell that they are not diamonds. The ring is comfortable as well, smooth against the finger. I don't think it's accurate to call it a "stackable" ring, though. The setting would not allow for another ring to be worn right up against this one. Also, please provide more sizing choices, especially half sizes!
