The cut of a diamond affect its price30 Sep 21
First and foremost, we need to take a couple of external factors into account, such as the global economy. The price of a diamond is always the result of supply and demand. The diamond supply is stable, but the demand is mainly affected by emerging countries such as India, Brazil, Indonesia and the Middle East.
Also the weight of the polished diamond is an important factor that determines the price of a diamond. The weight of diamonds is expressed in carat. Diamond prices rise exponentially as the diamond becomes heavier.
In addition to the weight, the purity of the diamond also has an influence on the price. This clarity is determined by the number and size of inclusions or imperfections in the diamond. While most diamonds seem to be colourless, they almost all have a slight hue. Pure colourless diamonds are, just like diamonds with a very intense colour, extremely rare and therefore precious.
Cutting a rough diamond
The last factor that affects the price of diamonds is the way the rough diamond is cut. Its light reflection depends on the correct proportions, the attention to detail and the shape in which the diamond is cut. This is the only human factor that affects the price of diamonds.
The cutting process of diamonds is based on mathematical formulas with different angles and surfaces in order to optimize the brightness and the brilliance of the diamonds. With coloured diamonds, this is even more important and more difficult than with colourless or white diamonds. Therefore, the intensity of the colour also plays an important role when determining the price of diamonds.
