Oval Cut Diamond

Almost identical to the traditional round cut diamond, but with a touch of creativity and uniqueness, this egg shaped diamond cut is a great diamond choice. Blessed with the fire and brilliance of a round cut diamond, the oval cut diamonds are the ideal choice for all those who wishes to get something that is different in shape yet possesses thesparkle which the round diamonds are so famous for. In short, they are an adaptation of the round brilliant cut diamond. The oval shaped stones are known as Briolettes and they do not have any culet, table or edge. They are basically surrounded by triangular-shaped facets. The elongated shape of an oval cut diamond gives the fingers a long and slender look. What’s more, the elongated shape also creates the illusion of a bigger sized diamond.

A classic oval cut diamond is one that has length to width ratio of 1.35-1.50 though the choice may vary from one individual to another. If you wish to flank your oval shaped diamond with small stones on the side, then a thin cut should be opted. What is interesting is that, most oval diamonds have a bow-tie effect which is the result of light not bouncing back in the middle of the diamond due to the way the diamond has been cut. This bow-tie effect is normally not taken into consideration during diamond grading nor is it mentioned on any diamond certificate. However, you will obviously not wish to have a diamond where the bow-tie effect is severe, and easily visible. So the best way is to perform a visual inspection of the diamond and judge the level of the bow-tie effect.
