WHAT DETERMINES THE PRICE OF A DIAMOND?
The size or weight, the shape, the colour and the clarity of each individual stone determine diamond pricing.
The size/weight
The size, which is determined by its weight in carats, determines part of the price of a diamond, and it goes up exponentially. A 0,10ct stone (a ten pointer) is not half the price of a 0,20ct stone (a twenty pointer). For example 0,01ct – 0,09ct stones are in one price bracket, then the price per carat jumps say from 0,10ct – 0,15ct and so on. If you find a 0,49ct ( which is very rare as they will try and cut it so that it hits 0, the price will be substantially lower than a 0,50ct, even though the diameter size might not seem that different to the average person’s eye.
