When shopping for a diamond, understanding the four "C's" — cut, color, clarity, and carat weight — is essential to making an informed decision. While many buyers focus on carat weight and color, clarity plays a crucial role in the overall beauty and price of the diamond. Clarity refers to the internal and external characteristics (or inclusions and blemishes) that occur naturally in diamonds. In this article, we will break down the clarity grading system, explain how inclusions affect the diamond's appearance, and help you determine which clarity grade is right for you.
What is Diamond Clarity?
Clarity is a measure of how free a diamond is from inclusions and blemishes. Inclusions are internal characteristics, such as tiny crystals or fractures, while blemishes are external imperfections like scratches or chips. The fewer inclusions and blemishes a diamond has, the higher its clarity grade.
The Gemological Institute of America (GIA) and the American Gem Society (AGS) are two of the most widely recognized laboratories for grading diamonds. Both use similar grading scales, ranging from flawless diamonds (with no visible inclusions) to diamonds with noticeable imperfections. Understanding these
scales will help you choose the diamond that best fits your needs and budget.
The GIA Clarity Grading Scale
-
FL (Flawless): No internal or external inclusions visible under 10x magnification. These diamonds are rare and highly valued.
-
IF (Internally Flawless): No internal inclusions, but may have minor external blemishes visible under magnification.
-
VVS1/VVS2 (Very, Very Slightly Included): Extremely difficult to see inclusions, even under 10x magnification. These diamonds are close to perfect and often mistaken for flawless diamonds.
-
VS1/VS2 (Very Slightly Included): Inclusions are small but visible only under magnification. These diamonds represent a balance of quality and price.
-
SI1/SI2 (Slightly Included): Inclusions are more noticeable under magnification and may be visible to the naked eye in SI2 diamonds, but they generally don't affect the diamond's overall brilliance.
-
I1/I2/I3 (Imperfect): These diamonds have obvious inclusions visible to the naked eye. The imperfections may impact the durability, brilliance, and overall appearance of the diamond.
Understanding the Impact of Clarity on Appearance
While clarity plays a significant role in a diamond’s value, its impact on beauty can be subtle. Most inclusions in diamonds graded VS2 and higher are microscopic and can only be seen under magnification. In fact, many diamonds in the VVS and VS ranges are "eye-clean," meaning their inclusions are not visible to the naked eye.
For diamonds graded SI1 or lower, inclusions may be visible to the naked eye. However, the location and type of inclusions are important. For example, a small inclusion on the side or at the bottom of the diamond might be less noticeable than one near the center.
Which Clarity Grade Should You Choose?
When selecting a diamond, it’s essential to balance clarity with other factors, such as color and cut. For those on a budget, diamonds with a clarity of SI1 or VS2 offer excellent value without sacrificing beauty. These diamonds may show slight imperfections under magnification but are still stunning when viewed from a normal distance.
If you want a flawless, high-end diamond, opt for a VVS or FL graded stone. These diamonds are rare, and their perfection comes at a premium price.
Expert Tips for Evaluating Diamond Clarity
-
Look for Eye-Clean Diamonds: Many diamonds in the VS2 and VVS range are eye-clean, meaning they appear flawless to the naked eye.
-
Consider the Cut: The brilliance and sparkle of a diamond are largely determined by its cut. A well-cut diamond can mask minor inclusions, so prioritize cut over clarity if you're looking for a diamond with maximum sparkle.
-
Understand the Lighting: Viewing a diamond under different lighting conditions can affect how inclusions appear. Be sure to examine the diamond under both darkfield illumination (to detect internal inclusions) and overhead lighting (to get a realistic view of how the diamond will look in everyday use).
Conclusion
Diamond clarity is an essential factor when selecting a diamond, but it’s important to remember that clarity doesn’t always affect the diamond’s beauty. While high-clarity diamonds are prized for their perfection, many diamonds with lower clarity grades still appear stunning to the naked eye and offer excellent value. By understanding the clarity scale and considering your personal preferences, you can find the perfect diamond that fits both your budget and your aesthetic desires.
