The 4C’s of Diamond Grading
In 1953, the Gemological Institute of America introduced the 4C diamond grading system. Before that, diamonds were described using only A, B, and C grades. Today, diamonds are rated using this universally accepted system. These four characteristics are the cut, color, clarity, and carat weight. To determine the quality of a diamond, it is important to understand each of these characteristics.
Cut – The cut grade is the most important of the the 4 cs of diamonds. It refers to a diamond’s symmetry, proportion, and cut, which all contribute to the brilliance of a diamond. A poorly cut diamond will appear dead and see-through, so it’s essential to get a well-cut stone.
Clarity – The clarity of a diamond is measured in metric carats. A diamond’s clarity grade is usually determined based on a first impression, and the grader will note whether the diamond contains inclusions or not. For most diamonds, clarity can be determined in less than 2 minutes. Internally and externally flawless diamonds, however, require a more thorough examination.

Carat Weight – This is another important part of a diamond’s value. Whether it is a round diamond or a pear-shaped diamond, the carat weight plays a major role in determining the value of the diamond. In addition to its carat weight, another important feature of a diamond is its cut. A diamond with a better cut will sparkle more than a diamond with a square cut.
Carat Weight – The carat weight of a diamond will be higher than a diamond with an inferior carat weight. Diamonds with higher carat weight will command higher prices. However, if you can afford it, you may want to consider buying the largest diamond you can afford.
Carat: The carat weight of a diamond is the most important C. A one-carat diamond is approximately 0.2 grams. Although it may seem like the largest C, it is not necessarily the biggest factor. Diamonds with the same carat weight can vary in size, so it’s essential to know this information so you can make a decision on the size of your diamond.
Clarity: Diamond clarity is the measurement of how clean a diamond is. The clearer the diamond is, the more valuable it is. Inclusions and blemishes are internal and external flaws, and can be present. Diamond clarity is measured by using a scale that gemologists and jewelers use to grade the clarity of a diamond.
Color: Diamonds come in a wide variety of colors. A diamond with no color is called a colorless diamond. Colorless diamonds are rare and expensive. Generally, colorless diamonds are graded D or higher. As the color scale progresses down the alphabet, diamonds appear more yellow, brown, or gray.
