Factors Affecting the Price of Diamond
Of the four factors, the cut has the highest importance in deciding the price, as the cut quality directly affects the amount of diamond you get from the diamond. Hence, it can be said that the cut unveils the beauty of the finished diamond by invoking shine out of the rough diamond.
The next most crucial element of pricing is the color. The pricing is determined according to the color grade as it is clearly appealing to the eye. However, clarity has the least importance in deciding the cost. This is because to detect the change in clarity, one needs to view the diamonds under at least 10x magnification.
Carat weight is another deciding factor in the price of a diamond. However, a 
diamond does not necessarily have to cost more just because it is heavier in weight. The other influencing factors have to be equivalently superior too in order to bring a change in the pricing. After all, the price of the diamond is a balanced figure of all the above factors.
