SCIENCE BEHIND THE BEAUTY

ENSURING "PROPER CARAT WEIGHT SPREAD"

The interaction between carat weight and cut quality determines how big a diamond will appear. The size a diamond looks is not just a matter of carat weight. When purchasing a diamond, people often mistake weight for visible size, because they assume if it weighs more it will look larger. Without realizing it, they pay more for ordinary diamonds with higher weight. However, a lighter, well cut diamond will actually create a larger more beautiful diamond. A poorly cut diamond hides unnecessary weight throughout the diamond, causing it to appear smaller than it should.

For instance, a poorly cut diamond weighing 2.10 carats can actually appear smaller than a well cut diamond weighing 1.90 carats. This is because of differences in the way the weight is distributed.

Our system for measuring visible size, known as "spread," makes certain that every Original Radiant Cut looks as large as it should appear. Our customers never pay for unnecessary carat weight that cannot be seen. We measure the "spread" of each Original Radiant Cut Diamond. Our measurements even account for the area lost as a result of the cut corners.

Minimum Original Radiant Cut Spreads for Carat Weights Note: Calculation takes into account the 5%-10% loss of surface area due to the cut corners. This measurement, done properly, is the only reliable method of ensuring that your diamond has sufficient spread.

1.50	40.0
2.00	49.0
3.00	64.0
4.00	76.0
