More About Diamond Shapes

The 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 diamond shapes at the proper reflection of light, maximizing potential brightness.
Virtually all round diamonds are brilliant-cut, meaning they have 58 facets (57 when there is no culet).
Round diamonds cost more on a per carat basis than fancy shapes for two reasons; the demand for round diamonds is very high, and the yield is relatively low. Because more of the rough stone is lost in the cutting of a round diamond, the cost of each carat retained is higher. A typical round diamond (for example; a 1.00 carat, F-colour, VS2-clarity, Ex cut) may cost 25-35% more than a similar fancy shape.

Diamond clarity is a term used to describe the absence or presence of flaws inside or on the surface of a diamond. A perfect diamond with perfect clarity, or clearness, is rare, and most flaws that do exist in jewelry grade diamonds cannot be seen without looking at the gems through a jeweler’s magnifying loupe.
