When choosing an emerald shaped diamond there are some specifics that you’ll want to look at. You don’t want to just get the first one you see, and you don’t want to automatically try to pick the largest one in an effort to impress your lady. You need to find an engagement ring that fits her finger properly, and some of that should be determined based on the size and cut of the diamond.
If you’re sure that an emerald shaped diamond is what you want then you’ll also need to be sure that you can find one that has a great setting and that looks like just what you want. You should look at the color, clarity and carat weight as well as the emerald cut, because all of those things are very important. They can definitely affect the way that the cut looks as well, and sometimes a beautiful cut can be marred by things like the color or the clarity of the diamond.
If there are imperfections in it or if it is cloudy or otherwise discolored, the cut will not matter as much as these kinds of issues.
