Clarity Education

What is diamond clarity?

In simple terms, clarity of the diamond refers to its purity and rarity. At the time of formation, few natural characteristics are trapped in the diamond, which are visible to the eye with a microscope. Gemologists inspect the diamond to check on internal and surface characteristics based on which clarity grade is assigned to each diamond. Diamonds having no or very less inclusions are rare and considered to be high on value.

Importance of diamond clarity

Experienced gemologists use 10X magnification to classify and identify diamond clarity by size, shape and type of diamond. Gemological labs like IGI and GIA measure diamonds on a scale ranging from flawless to included. The grading scale of GIA is divided into the below categories and clarity grades.

I1, I2, I3 Included Diamonds

This grade has inclusions that are visible and impact the overall beauty of the diamond.

SI1, SI2 Slightly Included (SI) Diamonds

Inclusions are noticeable with 10X magnification. To the unaided eye, inclusions are visible from the side of the stone.

VS1, VS2 Very Slightly Included (VS) Diamonds

Very slight inclusions are visible at 10X magnification. Offers great value for money.

VVS1, VVS2 Very, Very Slightly Included (VVS) Diamonds

Very minor inclusions that are difficult to spot even under 10X magnification for trained eye. Complete eye clean appearance and a rare clarity.

Internally Flawless (IF) Diamonds

Visually eye clean diamonds, having no inclusions in the stone, but only within the surface characteristics.

Flawless (FL) Diamonds

Less than 1% diamonds are of FL clarity and this diamond type is rare owing to its 100% free inclusions

Factors That Influence Diamond Clarity

Size: The more the number of characteristics visible, lower is the clarity grade

Number: This is the number of characteristics present in the diamond. Few characteristics mean that a diamond has high clarity grade.

Nature: This refers to the type of inclusion and the impact that it has on the durability of the diamond.

Color: This means how easily one can spot the characteristic in the diamond and the contrast between the characteristic and surrounding diamond.
