When somebody says a ‘diamond’, the first thing that comes to your mind is probably a diamond engagement ring like one from https://www.leohamel.com/. In our modern world, this is the primary function of diamonds, and most of us think about them in those terms.

So, if you have been diamond shopping, or you plan to do so soon, chances are you have heard about the four C’s of diamonds. All the experts tell you how these are very important and that they determine the beauty and the ultimate price of the diamond and the ring itself. So what are these, and how do they affect your diamond’s price?


So, let’s start with the most obvious and easy-to-see characteristic of diamonds – the color. Or should I say lack of color? In the simplest terms I can put it, the purest diamonds are colorless. The structure of diamond is pure carbon. However, various impurities can be trapped in it, giving it a slight hue or even strong color. However, the most esteemed diamonds are those with no impurities, therefore colorless.

The Gemological Institute of America, or GIA for short, has created a scale which is most commonly used to grade color of diamonds. The purest diamonds are given the classification ‘D’, and the scale goes alphabetically all the way to ‘Z’. The color differences are usually very subtle and laymen cannot perceive them, but they have a big impact on the price.


Diamonds are made through incredible pressure and high heat which compress carbon into a crystalline structure. However, depending on the environment where this creation process takes place, diamonds can have certain impurities, both internal and external. Internal impurities are called inclusions, whereas the external ones are called blemishes.

No diamond is completely clear, but the closer it comes to that designation, the better quality rating it is given. When evaluating the diamond’s clarity, an expert judges the size, number, and the position of these impurities, as well as their overall influence on the stone’s appearance.

Carat Weight

This is the simplest measure of the diamond’s worth, more specifically its weight. A single carat is translated into the metric system as 200 milligrams, which is just over 0.007 ounces. However, diamonds are usually small and valuable, which means that they need to be measured more accurately than that. Each carat is further divided into 100 points, creating a precise two-decimal point system.

Large diamonds are rare, so the size does play an important role in determining the price of diamonds, but it is by no means the only deciding factor. Even large diamonds can have significantly lower prices if other C’s are marked poorly. So, remember that size isn’t everything.


This is the final and the last member of the diamonds’ C’s. The cut is determined long after the diamond has formed in the belly of the Earth before it was mined and finally refined. We love diamonds because of their ability to refract light and sparkle. The main reason why they are able to do that is the cut. So, the cut doesn’t refer just to the shape (although it is a big part of it), but also to the ability of diamond’s facets to refract light.

In order to create these light shows we are so captivated by, master craftsmen need to inspect the diamond and determine the best cut to match the characteristics of the diamond. In the end, it is the quality of the cut that the customer will be able to admire the most, so it is an important step and an integral part of the diamond production.
