Diamonds are among the most well-liked gems around the world. The four C’s of a diamond according to the GIA (Gemological Institute of America) are Color, Carat, Clarity and Cut, and these traits collectively decide how much any given stone is worth on the market.
The mass of the diamond is always mentioned in carats. One carat is equal to 200 milligrams. Most often, the price of the diamond per carat is directly proportional to its carat weight. Larger diamonds are rare to find and are hence very expensive.
What does Carat Signify?
Carat actually signifies the weight of the diamond, although a lot of the time, people misread it as something representing the size of the stone. One carat equals 0.2 grams, as already mentioned.
Cut and Shape Can Affect Visible Size
The cutting ratio largely affects the size of a diamond. Higher carat of a diamond does not necessarily mean its size will be big. The latter largely depends upon the cut quality of the stone, which means there can be two diamond stones of same carat weight, but having different sizes. If the stone is cut to perfection, there would be a good amount of light returning from the facets, making the diamond appear bigger. However, if the stone is poorly cut, the extra weight will be hidden towards the base, and thus the diamond would appear smaller.
The shape of a diamond also affects its size. Diamonds which are of same carat weights but cut to different shapes can be of different sizes (depth and diameter). Therefore some diamonds can appear to be larger than the others. Because of the amazing difference a well cut diamond has from ordinary-looking ones, the value of the former can be placed very highly.
The Pricing Of The Stone
The price of a diamond stone is mainly determined by its weight. The clarity, color, and cut quality also affect the pricing of the diamond. Large diamonds are costlier than smaller ones, and are rarely available. The pricings of round and other fancy shaped diamonds may differ as well. Round diamonds have high demand in the market, and hence their prices are higher. But the cutting of the round shaped diamonds results in loss of a lot more material.
Total Carat Weight and Carat Weight
Though both total carat weight and carat weight sound to be the same, they are in fact different. Carat weight refers to the weight of an individual diamond stone, whereas total carat weight refers to the sum total of the carat weights of all the stones present in a combination of stones (usually set on a ring).
