When shopping for a diamond, most people focus on size and sparkle. But there’s another critical factor that greatly impacts a diamond’s appearance and value — clarity. This is where the diamond clarity chart becomes essential. Whether you’re buying a natural or lab-grown diamond, knowing how clarity works helps you make an informed, confident purchase.

What Is Diamond Clarity?

Diamond clarity refers to the presence (or absence) of internal and external flaws, known as inclusions and blemishes. Inclusions are imperfections inside the diamond, while blemishes are found on the surface. Most diamonds contain these to some extent, since they form under extreme pressure and temperature.

Clarity doesn’t usually affect a diamond’s durability, but it does influence how brilliant and clean the diamond looks — especially under magnification.

Why the Diamond Clarity Chart Matters

The diamond clarity chart is a standardized scale used to grade the clarity of diamonds. Developed by the Gemological Institute of America (GIA), this chart provides a clear, industry-accepted way to evaluate and compare diamonds. Even minor differences in clarity can significantly affect a diamond’s value.

Understanding this chart helps buyers:

• Avoid overpaying for higher clarity that might not be noticeable

• Choose a diamond that looks eye-clean (flawless to the naked eye)

• Balance clarity with other key aspects like cut, color, and carat

The Diamond Clarity Chart Explained

Here’s a breakdown of the diamond clarity grades from highest to lowest:

Visual Impact of Clarity Grades

While the chart defines clarity under magnification, what matters most to buyers is what you can see with the naked eye. Here’s how different grades typically appear:

• FL to VS1: Nearly all of these diamonds are eye-clean — even trained gemologists struggle to spot inclusions without tools.

• VS2 to SI1: Usually eye-clean, especially in smaller carat weights or well-cut stones.

• SI2 to I3: May show visible imperfections without magnification, and in lower grades, inclusions may affect transparency or durability.

Pro Tip: Focus on “Eye-Clean” Instead of “Flawless”

Most people cannot distinguish between an FL diamond and a VS1 diamond without a microscope. So rather than paying a premium for top-tier clarity, consider looking for an eye-clean diamond — one that appears flawless to the unaided eye. This often provides better value without compromising beauty.

Clarity in Lab-Grown vs. Natural Diamonds

Lab-grown diamonds follow the same clarity chart as natural diamonds. However, lab diamonds are often available in higher clarity grades at lower prices. That’s because controlled environments reduce the number of inclusions during formation.

Still, lab-grown diamonds can have:

• Metallic inclusions (from the growth process)

• Clouds or graining from rapid crystal growth

These are assessed the same way and should be part of your diamond grading report.

How Clarity Affects Price

Clarity has a direct impact on diamond pricing. Here’s a general guide:

• FL/IF diamonds are rare and command the highest prices.

• VVS1–VS2 diamonds offer high quality with fewer visible flaws.

• SI1–SI2 diamonds can provide excellent value if they’re eye-clean.

• I1–I3 diamonds are budget-friendly but often visibly included.

Even a single grade difference can mean hundreds or thousands of dollars, depending on the size and shape of the diamond.

Choosing the Right Clarity Grade: What to Consider

Here are some helpful tips to choose the best clarity for your needs:

1. Budget

If you’re working with a budget, aim for VS2 or SI1 clarity — many are eye-clean and cost much less than FL or VVS stones.

2. Diamond Shape

Some shapes hide inclusions better than others. For example:

• Brilliant cuts (round, oval, cushion) hide flaws better due to more facets.

• Step cuts (emerald, Asscher) show imperfections more clearly.

3. Carat Weight

In larger diamonds (1.5+ carats), inclusions are easier to see. You may want a higher clarity grade for larger stones.

Final Thoughts

The man made diamonds is an indispensable tool when buying a diamond. But clarity is just one piece of the puzzle. Instead of chasing a flawless diamond, focus on finding a well-cut, eye-clean stone that suits your style and budget. Whether you’re investing in a timeless engagement ring or a lab-grown statement piece, understanding clarity ensures you get the sparkle you deserve.
