18 karat gold is 75% pure gold and for this reason, for a given CZ stone, an 18k white gold cubic zirconia engagement ring will tend to be more expensive than a similar band made from less pure alloys such as 14k and 10k white gold.

Usually the discussion begins with the choice of band, but clearly in the case of 18k white gold CZ engagement rings, the requirement is quite clear! It has to be white gold…and 18k! Hence we jump straight into the topic of stone cuts that may feature on such rings. Well, as always, cut and band are independent attributes. Thus you are able to find any cut you like to grace such rings. Popular choices include princess-cut 18k white gold cubic zirconia engagement rings and round-cut ones. Even though many other fancy cuts exist, surprisingly on Amazon, out of 185 rings that fit the bill, these are the only two cuts in which they come. That surely is a testament to the popularity of these two cuts.
