Diamond Grading – Clarity

Clarity: a Rarity

Diamonds, more than any other gemstone, can produce the maximum amount of brilliance. A diamond that is virtually free of interior or exterior inclusions (commonly known as flaws) is of the highest quality, for nothing interferes with the passage of light through the diamond. To determine a diamond’s clarity, a trained eye views it under a 10-power magnification. The flawless diamond contains no minute inclusions that mar its beauty or endanger its durability.

Clarity is broken down into five different classification. Several diagrams inside this packet discuss the size and location of an inclusion that classifies a diamond’s clarity. The first classification is Flawless (F1), where no inclusion exists in the diamond. The second is Very, Very, Small Inclusions (VVS).

This classification has two levels, VVS1 and VVS2. Referring to the diagram for VVS1 you will see eight sets of a diamonds’ table (left) and girdle (right). The text below each table/girdle pair discusses the size and location of the inclusions. The third classification is Very Small Inclusions (VS). Again the VS classification has two levels. Refer to the diagrams for VS1 and VS2 to determine the difference between the VVS and VS classifications. The fourth classification is Small Inclusions (SI) which also has two levels. Finally, the fifth classification is Imperfect (I) which has three levels. Diagrams also exist for the SI and I classifications.

The Flawless diamond is certainly the most expensive choice; however, the VVS class inclusion is not noticeable to the naked eye. Refer to the diagram entitled “Clarity Grading Scale” to see how each classification ranks with the other.
