Thanks to nature, every diamond is unique. This could be due to minute traces of other minerals trapped during the crystallization process. These natural characteristics, called inclusions, are better described as nature’s fingerprints and help gemologists determine the age of a diamond.
The number, color, nature, size, and position of any inclusions determines the clarity of a diamond. The fewer the inclusions, the rarer it will be graded, and the more light it will reflect, making it more valuable.
