Cut refers to the angles and proportions a skilled craftsman creates in transforming a rough diamond into polished diamonds. Nature determines so much about a diamond, but it takes a master cutter to reveal the stone’s true brilliance, fire and ultimate beauty.
Based on scientific formulas, a well-cut diamond will internally reflects light from one mirror like facet to another and disperse ..
When light enters a diamond, it is reflected and refracted out. If there is any thing disrupting the flow of light in the diamond, such as an inclusion, proportion of light will be lost. As a result brilliance could be diminished. The number of inclusions can determine the degree of brilliance.
Inclusions, which are sometimes referred to as “Nature’s Fingerprints”, are usually not visible to the naked eye unless magnified.
The best color for a diamond is no color. Because it is the totally colorless diamond that acts as a prism, allowing light to pass effortlessly through the diamond and be transformed into rainbows of color. To give a woman the purest white diamond is to show your true colors as well.
The color grading scale goes from totally colorless to light yellow. The differences between one grade and another are very subtle..
Carat is often confused with size even though it is actually a measure of weight. Sometimes, you might think a larger diamond appears more brilliant than a smaller one. This is because light must travel a greater distance through a larger diamond. The result is a prism effect that your eye registers as more brilliance and fire. One carat is divided into 100 “points” so that a diamond of 75 points weights .75 carats.
