Understanding Diamond Clarity: A Complete Guide Before You Buy. When buying a diamond, one of the most important aspects to consider is clarity. Many people mistakenly believe that clarity refers to how transparent or “clear” a diamond looks. In reality, clarity refers to the presence or absence of internal flaws (inclusions) and external flaws (blemishes).
What Is Diamond Clarity?
Clarity is a grading of how free a diamond is from natural imperfections. Because diamonds form under intense heat and pressure deep within the Earth, it’s common for them to have small flaws. These flaws can appear as spots, cracks, lines, or scratches either inside the diamond or on its surface.
The fewer the flaws and the less visible they are the higher the diamond’s clarity grade and value.
Two Main Clarity Categories
In general, diamonds fall into two broad clarity categories:
-
Diamonds with visible inclusions and blemishes:
These diamonds have imperfections that can be seen with the naked eye. -
Eye-clean diamonds:
These diamonds may have imperfections, but they are not visible without magnification. To the naked eye, they appear flawless.
The Diamond Clarity Grading Scale
The Gemological Institute of America (GIA) has developed a standardized clarity grading scale, which is widely used in the diamond industry:
-
FL (Flawless):
No inclusions or blemishes visible under 10x magnification. The highest clarity grade. -
IF (Internally Flawless):
No inclusions visible under 10x magnification, but may have very minor surface blemishes. -
VVS1 & VVS2 (Very, Very Slightly Included):
Extremely tiny inclusions that are very difficult to detect, even under magnification. -
VS1 & VS2 (Very Slightly Included):
Minor inclusions that are difficult to see under 10x magnification, but more noticeable than VVS. -
SI1 & SI2 (Slightly Included):
Inclusions are noticeable under 10x magnification and might be visible to the naked eye in some cases. -
I1, I2, & I3 (Included):
Obvious inclusions visible without magnification. I3 diamonds have the lowest clarity and are less desirable for fine jewelry.
Tips for Choosing the Right Clarity
-
If you want a diamond that looks flawless to the eye but doesn’t break the bank, consider VS1 or SI1 clarity grades. These often appear eye-clean while being much more affordable than FL or IF diamonds.
-
For engagement rings or gifts, eye-clean diamonds are a smart and budget-friendly option.
-
Always inspect the diamond using a loupe (10x magnification) or ask a gemologist for a clarity assessment before purchasing.
Conclusion:
Clarity is one of the essential 4Cs of diamond quality, alongside Cut, Color, and Carat. Understanding how clarity works and how diamonds are graded will help you make a more informed and confident buying decision—whether you’re shopping for an engagement ring, a gift, or an investment.
