Larger diamonds are much more rare than smaller ones. In fact. hundreds of tons of rock and ore must be processed to uncover a single one-carat gem quality diamond, and less than one percent of all women will ever own a one- carat or larger diamond.

Since a carat is a unit of measure and not size, two diamonds of the same carat weight may appear to be different sizes depending on how the diamond is cut. Some diamonds will have extra weight on the bottom part (or pavilion) of the stone, and therefore appear smaller. A Hearts On Fire diamond is perfectly cut, and will appear larger than many diamonds of a heavier carat weight.
