Princess cut diamonds are the second most popular shape diamond for engagement rings. They are a wonderful option for people that like the brilliance of a round diamond but prefer a more square appearance. They will appear smaller than round diamonds, though, due to their shape and typically greater depth. The top of a Princess-cut diamond is either square or rectangular, while the bottom looks like an inverted pyramid. Princess cut diamonds are a relatively new diamond cut and were specifically designed to maximize brilliance. This is largely due to the fact that they are cut to follow the natural crystalline structure of the diamond. They also offer great value per carat, as more of the rough diamond is preserved in the cutting process. Princess diamonds are cut to achieve the highest degree of brilliance and offer maximum light return.
Oval diamonds are popular choice for engagement rings because they offer great fire and brilliance. Similar to round diamonds in their light return, oval-cut diamonds are known for their unique shape and aesthetic appeal. This diamond shape has an additional advantage of appearing larger than its actual carat size because of its elongated shape. When set in engagement rings, oval-cut diamonds serve to elongate fingers, which gives them an air of grace and elegance.
A marquise-cut diamond is considered a classic diamond shape because it compliments any engagement ring. When selecting a marquise diamond, color and clarity are the two most important aspects to consider. A marquise diamond is cut in a way that is similar to a round brilliant diamond, except the carat weight of the stone is maximized by lengthening it into its highly recognizable boat-shape. Unfortunately, because marquise-cut diamonds have such a distinctive elongated shape, imperfections and flaws are more pronounced than they are in traditional round brilliant diamonds.
