You have to either wear a one-carat diamond ring on the finger or at least get an idea of how it looks prior to selecting it. Carat refers to the weight of the gem. However, a one-carat high-quality diamond will have smaller dimensions than a cheaper gem. There are many different diamond cuts to choose from, although modern round brilliant is the most popular option for a solitaire ring. This is owing to the big face of the cut, meaning the diamond’s diameter gives the impression of bigger carat weight. Though the gemstone is typically extremely shallow, its pavilion is faceted heavily and thus it gives off exemplary brilliance. Princess cut is the second most popular diamond cut; it features a rectangular or square shaped top as well as a highly faceted bottom portion below the girdle, like modern round brilliant, to achieve a higher shine. The oval diamond cut is yet another popular option, which also benefits from a big face, meaning a high proportion of the gem is visible from the top. Your ring band setting can also make it look further bigger.
