4 C’s of a diamond

Diamond Cut

The GIA (Gemological Institute of America), first devised this concept of the 4 C’s of a diamond. It was introduced to bring a grading system into place when it came to determining the quality of a diamond. The 4 C’s of a diamond dictate the value, elegance, and style of a diamond. They are Carat, Cut, Color and Clarity. 

Knowing each characteristic will help you to compare between two diamonds that look the same but are actually different. You will be able to understand and identify the quality of a given diamond. By doing so, you will also be able to establish a balance between a diamond’s value and price. Jewel Hero’s diamond buying guide, will take you through the four C’s elaborately so that you can choose a diamond based on your budget, lifestyle, and preference. 

For now, let’s get a brief understanding about the 4 C’s of a diamond. 


The weight of a diamond is denoted by its carat. When your local jeweler tells you that a particular diamond has one carat, he/she means that the diamond has a weight of 0.20 grams. This is very much different when it comes to the karat which is used in gold. The karat in gold is a measure of its purity whereas in diamond it tells you about the weight. So a diamond of a higher carat does not need to have an increased size in particular. The size and surface area of a diamond will depend from one diamond to another.


The cut of a diamond dictates the amount of sparkle, fire, and brilliance in it. A diamond’s dispersive power and its ability to reflect and bounce back light depends on the way in which a diamond is cut and faceted. That is why it’s very important to look for a diamond’s cut when you are buying a diamond. You will then be able to feast on a diamond that has the maximum sparkle and elegance. The cut of a diamond can also be a visual treat to the eye. 


As natural diamonds are created in natural fashion, they might have a slight tint of shade of yellow / brown as a result of the impurities deposited in it. The GIA has devised a grading system wherein you can choose the best diamond in terms of color. The grading system of a diamond declares that the diamond which is most colorless is the most valuable in terms of the style, elegance and beauty of the diamond. The value of a diamond depreciates as the presence of yellow and brown shades becomes visible in it. The color of a diamond is determined by evaluating the body color of the diamond with reference to a pure white sample.


Diamonds come along with natural imperfections, given the fact that they undergo dynamic processes before getting into the hands of the diamond cutter. These imperfections or microscopic impurities present within the diamond are called inclusions.  The GIA devices a grading system in which diamonds are classified based on inclusion type, extent of damage and other gradings. Based on your budget, you can buy diamonds of the best diamond clarity. Generally, you won’t have to bother about diamond clarity as inclusions only come visible under 10x magnification.
