EDUCATION ON DIAMONDS
Cut represents the proportion, symmetry, and polish of a diamond. The better proportioned a diamond is, the more brilliant it appears. Diamonds that are not well-proportioned will not capture and scatter light well. This will result in a loss of brilliance for the diamond.
Clarity is the quality measurement of inclusions and blemishes a diamond has internally. Blemishes and inclusions will obstruct the light that passes through the diamond, which can affect the appearance of the diamond. Blemishes and inclusions differ in location, size, and shape. These blemishes and inclusions are unique and usually formed naturally. However, it is possible that a blemish occurred during cutting of the diamond. Fortunately, with most gem quality diamonds, these inclusions and blemishes are not visible to the naked eye.
Diamonds can come in a range of colors (Fancy Color). Some are more rare and valuable than others. The majority of diamonds are in a range of pale yellow or brown color. The most beautiful color for a diamond is with no color at all. The purist diamonds will be colorless and appear to be a bright white. The scale, which was developed by the Gemological Institute of America (GIA), to measure diamond color ranges from 'D' to 'Z' or colorless to yellow.
Carat is the unit of measurement used to weigh diamonds and other gemstones. One carat is equal to 200 mg. A carat is divided into 100 points where each point is equal to two mg each. It is important to note that two diamonds with the same carat weight, may have different values due to the clarity, cut, and color of each diamond.
If a diamond is certified, it will come with a certificate that contains the diamond's precise measurements, color, cut, weight, and clarity. This certificate is considered a grading report of a diamond.
