Converting Oval Shaped Diamonds From Millimeters To Carat Weight

White Oval Loose Diamond

Oval Shaped Diamonds

Invented in the early 1960s, the oval shaped diamond is recognized as a modification of the most famous and traditional round brilliant cut diamond. The oval cut diamond has 56 facets, meaning it more or less has all the brilliance and shine of a round diamond, with just that little distinctiveness you may be looking for. Oval diamonds are most commonly used as center stones for items of jewelry such as rings or pendants, but a pair of smaller oval diamonds is often considered as side stones for a larger brilliant center stone.
