\nFollowing is an introduction to each shape, including information on how to determine the best combination of size, color, and clarity for your needs. \n\n\n\nROUND DIAMONDS\n\nThe round cut diamond is the most popular diamond shape, representing approximately 75% of all diamonds sold. Due to the mechanics of its shape, the round diamond is generally superior to fancy shapes at the proper reflection of light, maximizing potential brightness.\n\n\nPRINCESS CUT DIAMOND\n\nThe princess cut diamond, first created in 1980, is the most popular fancy diamond shape, especially for engagement rings. Like round cut diamonds, princess cut diamonds are a good choice for their flexibility in working in almost any style of ring. \n\n\nOVAL DIAMONDS\n\nBecause the oval diamond is a modified brilliant-cut (like virtually all round cut diamonds), the two diamond shapes possess a similar fire and brilliance. However, oval cut diamonds have the added advantage of an elongated shape, which can create the illusion of greater size.\n\nMARQUISE DIAMOND\n\nThe marquise cut diamond is a football-shaped, modified brilliant-cut. Because the marquise diamond is long and narrow, it can also create the illusion of greater size. Carat for carat, the marquise diamond has one of the largest surface areas of any diamond shape, making it a good choice when trying to maximize perceived size. \n\n\nPEAR SHAPED DIAMONDS\n\nThe modified brilliant-cut pear shaped diamond is a combination of a round and a marquise shape, with a tapered point on one end. Ideally, a pear shaped diamond should possess excellent or very good symmetry. The point should line up with the apex of the rounded end. The shoulders and wings (the upper and lower curves on the right and left side of the diamond) should form uniform, symmetrical curves. \n\n\nCUSHION CUT DIAMOND\n\nThe cushion cut diamond combines a square cut with rounded corners, much like a pillow (hence the name). This classic cut has been around for almost 200 years, and for the first century of its existence was the most popular diamond shape (similar to round cut today). Refinements in cut have led to a recent resurgence in popularity. \n\n\nEMERALD CUT DIAMONDS\n\nThe unique look of the emerald cut diamond is due to the step cuts of its pavilion and its large, open table. Instead of the sparkle of a brilliant-cut, emerald cut diamonds produce a hall-of-mirrors effect, with the interplay of light and dark planes. Often, inclusions or body color are easier to see in an emerald cut diamond.\n\nASSCHER CUT DIAMONDS\n\nThe asscher cut diamond was first produced in 1902 by the Asscher Brothers of Holland, an is a forerunner to the emerald cut. The asscher cut diamond is similar to the emerald cut, but in a square shape with larger step facets, a higher crown, and a smaller table. This combination often produces more brilliance than the emerald cut.\n\nRADIANT CUT DIAMONDS\n\nThe radiant cut diamond is the first rectangular cut to have a complete brilliant-cut facet pattern applied to both the crown and pavilion, creating a vibrant and lively diamond. The modified square shape is a nice bridge between a cushion and a princess cut, and for that reason looks beautiful set with both rounded or square cornered diamonds. \n\n\nHEART SHAPED DIAMONDS\n\nThe modified brilliant-cut heart shaped diamond is a unique and unmistakable symbol of love, popular in solitaire pendants as well as rings. Heart shaped diamonds less than .50 carats may not be a good choice, since the heart shape is more difficult to perceive in smaller diamonds, especially after they are set in prongs.
