Impurities in purely natural diamonds are mainly because of the existence of organic minerals and oxides. The clarity scale grades the diamond based upon the color, sizing, area of impurity and amount of clarity seen under 10x magnification.[sixty one] Inclusions in diamond could be extracted by optical methods. The method would be to consider pre-improvement photos, identifying the inclusion elimination part And at last getting rid of the diamond sides and noises.[62]
Over-all, the whole process of diamond development is a complex a single that occurs in excess of tens of millions or even billions of many years underneath precise geological conditions.
