Carat Weight

The color grading scale varies from completely colorless to a light color or tinted. The difference between one grade and its neighbor is very subtle.

Because of their unique optical properties, diamonds, more than any other gemstones, are capable of producing the maximum amount of brilliance. While minute minerals are contained in almost all diamonds, a diamond that is virtually free of inclusions and surface markings will be judged as flawless. To determine a diamond’s clarity grading, it must be examined under a 10x magnification by a trained, skilled eye. What minor inclusions there may be make every diamond unique. These are, in fact, nature’s fingerprints and do not mar the diamond’s beauty nor endanger its durability. Without high magnification, you may never see these inclusions. However, the fewer there are, the rarer and more expensive your diamond will be.

A diamond’s cut is crucial to the jewel’s final beauty and value. It represents the proportions, polish and symmetry of the stone’s facets to deliver the best transmission of light in order to intensify its sparkle and brilliance. In addition, the diamond’s weight relative to its diameter and depth affects its appearance and size.

How a Diamond Handles light

When a Diamond is cut to good proportions, light is reflected from one facet to another and then dispersed through the crown.

If the cut is too deep, light escapes through the opposite side of the pavilion or bottom.

If the cut is too shallow, light escapes through the pavilion before it can be reflected.

As with all precious stones, the weight of a diamond is expressed in carats.
One carat is divided into 100 “points” so that a diamond of 25 points is described as a quarter of a carat or 0.25 carats. Size is the most obvious factor in determining the value of a diamond, and two diamonds of equal size can have very unequal prices depending on their quality. Here are some other examples that show the approximate size of diamonds and their measurements of varying carat weights.
