I am looking for a 1.5-1.75 carat round diamond for my e-ring. The jewelers we visited said Old European Cuts are less expensive because they are less sparkly, but they tend to not be certified. One jeweler was able to show us one, side by side with a round brilliant. It looked good, and was much less expensive than the round brilliant, but was not certified. I do not feel comfortable buying a diamond that is not certified and I feel discouraged by the lack of certified options online. If OECs tend to be less expensive, I will continue to seek out a source because I do like the way they look. Thanks.
