The Four C’s:
Clarity, Color, Cut and Carat
Before selling the diamond, it’s important to know the clarity, color, cut and carat.
Clarity refers to the amount and location of flaws and blemishes when viewed under 10x magnification. The GIA rates clarity grades from Flawless to Imperfect 3. “Inclusions,” considered birthmarks, may be presented on some diamonds. The fewer the inclusions, the more brilliance the diamond since these inclusions can interfere with the light passing through.
Colors are graded from totally colorless to light yellow. Diamonds come naturally in every color. However, most people prefer diamonds in the white range. A colorless diamond is favored since it allows more light to pass through causing it to be disperse as the color of the rainbow.
The Diamond’s Cut is determined by the proportions of it as opposed to its shape (round, pear, princess, etc.). A diamond’s brilliance and scintillation is dependent on the cut and polish of the diamond’s facets. The idea is to allow the maximum amount of light through the top then reflecting and dispersing it back.
The Carat weight is the weight of a diamond measured in carats. This is the standard unit of weight for diamonds and other gemstones. Carats are divided into 100 points. For example, a 50-point diamond weights 0.50 carats. As the carat weight increases, so does the rarity and the price. The carat weight is the easiest of the four C’s to determine but two diamonds of the same weight does not mean they will have the same value.
