A diamond's price is made up of different components. The shape, clarity, carat weight as well as the colour all affect the price.
When choosing a diamond, it is important to obtain a description of all its qualities. The rarer it is, the higher the price. The four C's together determine the value of a diamond. This means that you can choose from a number of options for the cutting process: ideal, premium, very good, good, fair or poor.
The quality of the stone and the cutting process determine the price of the finished diamond. Diamond cutters always try and obtain the maximum diamond weight from the rough stone. A well-cut brilliant diamond typically weighs about 40% of the original weight of the rough stone. A diamond cut from a poor stone therefore results in an even larger weight loss.
Finally, you should not forget when purchasing a diamond, that it will always retain its quality and value.
