When embarking on the journey to find the perfect diamond, you’ll inevitably encounter the “4Cs,” one of which is Clarity. This characteristic refers to the absence of inclusions (internal flaws) and blemishes (surface flaws) within a diamond. Naturally, this leads to the question: What diamond clarity grade is considered the best? The answer, like many aspects of diamond buying, is nuanced and depends on your priorities.
Understanding the Clarity Scale: A Hierarchy of Imperfections
Before diving into the “best,” it’s crucial to understand the hierarchy. The Gemological Institute of America (GIA) developed the most widely accepted clarity grading system, which ranges from Flawless (FL) to Included (I3):
- Flawless (FL): No inclusions or blemishes are visible to a skilled grader using 10x magnification.
- Internally Flawless (IF): No inclusions are visible under 10x magnification, but minor blemishes (surface imperfections) may be present.
- Very, Very Slightly Included (VVS1 and VVS2): Inclusions are so minute that they are extremely difficult for a skilled grader to see under 10x magnification.
- Very Slightly Included (VS1 and VS2): Inclusions are minor and range from difficult to somewhat easy for a skilled grader to see under 10x magnification.
- Slightly Included (SI1 and SI2): Inclusions are noticeable under 10x magnification and may be visible to the naked eye.
- Included (I1, I2, and I3): Inclusions are obvious under 10x magnification and are usually visible to the naked eye. These inclusions can affect the diamond’s brilliance and structural integrity.

Is Flawless Really the Best? A Cost-Benefit Analysis
Logically, a Flawless (FL) diamond would seem to be the “best.” After all, it’s the purest, most perfect expression of a diamond. However, achieving this perfection comes at a significant premium.
- Rarity = High Price: FL diamonds are incredibly rare, making them considerably more expensive than diamonds with slight imperfections.
- Minimal Visual Difference: The inclusions in VVS and VS diamonds are so minuscule that they are practically impossible to detect without specialized equipment and trained eyes. To the average person, these diamonds will appear flawless.
The “Eye-Clean” Sweet Spot: VS1 and VS2 Diamonds
For most buyers, the goal isn’t necessarily to obtain a flawless diamond, but rather to find an “eye-clean” diamond. This means the diamond appears free of inclusions to the naked eye. This is where VS1 and VS2 clarity grades shine.
- Excellent Value: VS1 and VS2 diamonds offer a fantastic balance between clarity and price. They provide a near-flawless appearance without the exorbitant cost of FL or IF diamonds.
- Peace of Mind: Knowing your diamond has minor imperfections visible only under magnification can provide a sense of comfort, knowing it’s a genuine, natural gemstone.
When Clarity Matters Most: Diamond Size and Shape
The importance of clarity can also depend on the size and shape of the diamond:
- Larger Diamonds: In larger diamonds (over 1 carat), inclusions become more noticeable. Investing in a higher clarity grade (VS or VVS) may be worthwhile.
- Step-Cut Diamonds: Step-cut diamonds, such as Emerald and Asscher cuts, have large, open facets that make inclusions more visible. Higher clarity grades are generally recommended for these cuts.
- Brilliant-Cut Diamonds: Brilliant-cut diamonds, such as Round and Princess cuts, have many facets that help to mask inclusions. You may be able to get away with a slightly lower clarity grade (SI1) in these cuts.
Beyond the Grade: Factors to Consider
While the clarity grade is a helpful guide, consider these factors:
- Type and Location of Inclusions: Some inclusions are more visible than others. Dark inclusions or those located near the center of the table (the flat top of the diamond) are more noticeable than small, colorless inclusions near the girdle (the edge of the diamond).
- Personal Preference: Ultimately, the best diamond is the one that you find most beautiful. If you are comfortable with a diamond that has slight imperfections, there’s no reason to pay extra for a higher clarity grade.
The Verdict: The “Best” Clarity Grade is Subjective
There is no single “best” diamond clarity grade. For most buyers, VS1 and VS2 represent the sweet spot, offering excellent value and a visually flawless appearance. However, consider your budget, diamond size and shape, and personal preferences when making your decision.
Don’t get caught up in the pursuit of unattainable perfection. Focus on finding a diamond that is eye-clean, sparkles beautifully, and brings you joy. With a little research and a discerning eye, you can find a diamond that is both stunning and a wise investment.
