Clarity
Almost every diamond has a unique nature fingerprint.Clarity refers to the purity of the diamonds or to the degree that it is free of inclusions. Most diamonds have natural inclusions. But the value of a diamond increases in proportion with its clarity grade. The clarity of a polished diamond is affected by both external blemishes and internal inclusions, which were created either by nature during the crystallization of the gemstone or in the course of the cutting and polishing process (or as a result of wear and tear after being worn with jewellery).
