The internationally recognized criteria for determining the quality of diamonds are the so-called 4Cs.
They are classified as follows:
| Carat: | The weight of a diamond is measured in carats. One carat equals 0.2 grams. |
| Color: | The best color of a diamond is complete colorlessness. In a perfectly colorless diamond, white light passes effortlessly through the stone and emerges in rainbow colors. |
| Clarity: | Most diamonds contain very small inclusions. The fewer and smaller these inclusions are, the better the light can pass through the stone. |
| Cut: | The cut and proportions, the so-called ‘finish’, are among the most important characteristics of a diamond. The number and distribution of the facets on the crown and pavilion, their symmetrical arrangement, and their angles determine the brilliance of a diamond—together with the table size and the ratio between the upper and lower parts. |
