Diamonds are formed deep within the earth, under extreme heat and pressure. This creates unique birthmarks, either internal (inclusions) or external (blemishes). These birthmarks are not a bad thing per se, since they make the diamond truly unique.

Diamond clarity refers to the absence of these inclusions or blemishes. Diamonds with no birthmarks are extremely rare, and rarity affects a diamond's value.

GIA assigns a clarity grade by looking at the diamond's imperfections in terms of size, nature, position, color or relief and quantity under 10x magnification.

The GIA clarity scale contains 11 grades, with most diamonds falling into the VS (very slightly included) or SI (slightly included) categories.

• Flawless (FL): no inclusion or blemishes are visible using 10x magnification
• Internally Flawless (IF): no inclusions and only blemishes are visible using 10x magnification
• Very, Very Slightly Included (VVS1 and VVS2): inclusions are difficult to see under 10x magnification
• Very Slightly Included (VS1 and VS2): inclusions are minor although easier to see under 10x magnification
• Slightly Included (SI1 and SI2): inclusions are noticeable under 10x magnification
• Included (I1, I2, and I3): inclusions are visible under 10x magnification and to the naked eye and may affect transparency and brilliance of the diamond.

The clarity grade will be written down in the GIA certificate of your diamond. Learn about the importance of having a GIA certificate and how to read a GIA certificate.

In the “additional grading information” section of the GIA certificate, you will see an entry called “clarity characteristics” which will list the inclusions and blemishes present in the diamond.

The diamond displayed above has inclusions listed as pinpoint, cloud and feather.

You do not have to get a Flawless diamond to have a beautiful diamond to the naked eye. We recommend VS (very slightly included 1 or 2) or higher. Do not go lower, or inclusions will start becoming visible and affect the overall beauty of the stone.
