TL;DR: The Diamond Clarity Cheat Sheet
- Eye-clean clarity (VS1-SI1) looks identical to flawless diamonds when worn, so you're not paying extra for magnification you'll never use.
- SI1 is the sweet spot. Inclusions are impossible to see without magnification, giving you beauty and value without compromise.
- Your diamond clarity grade should match your setting, not drain your budget; solitaires need higher clarity, but halos and layering pieces don't.
- The jump from SI1 to VS1 costs 15 to 25% more, but the visual difference is virtually undetectable to the naked eye in daily wear.
- GIA certification confirms your clarity rating, giving you confidence that what you're buying is exactly what you're getting for your best quality diamond.
When you're shopping for diamond jewelry, you want to feel confident in your choice. One of the biggest decisions you'll make involves understanding diamond clarity. But let's be honest, it can feel overwhelming at first.
Here's the good news: clarity doesn't need to be complicated. Whether you're looking at an engagement ring, a pair of earrings, or a tennis necklace, understanding how diamond clarity works helps you find a stone that feels right for you and fits your budget.
What Is Diamond Clarity?
Diamond clarity measures how free a stone is from inclusions (internal marks) and blemishes (surface marks). Every diamond carries unique characteristics created over billions of years under extreme pressure. These don't diminish value; they make your stone one-of-a-kind.
How Diamond Clarity Gets Graded
When gemologists grade diamond quality clarity, they examine stones under 10x magnification using specialized tools.
They evaluate:
- Size of inclusions present
- Number of characteristics visible
- Location within the stone structure
- Type of inclusion or blemish
- Visibility to the naked eye
The key truth? What matters is whether you can see marks without magnification. For everyday wear, the way you'll actually wear your jewelry, that's what really counts. Most diamonds contain some characteristics. The question isn't whether they exist; it's whether they matter to you.
Why Diamond Clarity Matters
Clarity affects how light travels through your stone. Fewer inclusions mean light bounces more freely, creating more sparkle and brilliance. However, once you reach certain clarity levels, the difference becomes invisible to the naked eye. This is crucial information when making your purchase decision.
Understanding the Diamond Clarity Rating Chart
The diamond clarity rating chart uses the GIA standardized scale, the global standard recognized everywhere you shop for diamond rating charts. Whether you're in Chicago, New York, or anywhere else, these grades mean the same thing worldwide.

What's the Best Diamond Clarity for You?
Here's what surprises most people: the best diamond clarity isn't always the highest grade. It's the clarity that works for you: your budget, your priorities, your piece.
Why Higher Isn't Always Better
The human eye can't see inclusions below certain clarity levels. A stone graded SI1 or VS2 looks equally brilliant as a VVS stone when you're wearing it. The difference? You're not paying extra for magnification you'll never use.
A flawless diamond costs significantly more, but you won't see that difference in daily wear. That premium pays for rarity, not practical beauty.
Finding Your Best Quality Diamond Sweet Spot
For engagement rings, choose VS1 to SI1. Any inclusions are impossible to see without magnification. These grades give you confidence and beauty without unnecessary cost. This is where most smart shoppers land.
For earrings and stacking pieces, SI1 and SI2 work beautifully here. Inclusions are hidden or out of view when worn. You get stunning sparkle and save money at the same time.
For larger center stones (2+ carats), VS2 becomes more thoughtful. Larger diamonds can show inclusions more readily, so slightly higher clarity is a smart choice.
For bridal sets and layering, SI grades are perfect. The focus spreads across multiple pieces, so individual stone perfection matters less.
The honest truth? The best quality diamond is one you'll love wearing every day.
Breaking Down the Key Diamond Clarity Grades
The Grades Most People Choose
VS1 & VS2 (Very Slightly Included): This is the real sweet spot for fine jewelry. Inclusions are minor and only detected under 10x magnification by a trained eye. Your stone will be brilliant, beautiful, and genuinely eye-clean. You get the confidence of quality without paying a premium for invisibility.
SI1 & SI2 (Slightly Included): This is where accessibility meets beauty. At SI1, inclusions are usually impossible to see without magnification. SI2 might show an inclusion occasionally, but in a finished piece, especially an engagement ring where the setting frames the stone, you won't notice it. These grades offer tremendous value.
The Premium Tiers
VVS1 & VVS2 (Very, Very Slightly Included): If absolute perfection matters to you, these grades deliver. Inclusions are so minimal that they're nearly impossible to find without professional equipment. These diamonds cost more, but if you want that peace of mind, they're worth it.
FL & IF (Flawless & Internally Flawless): These represent the top tier of rarity. A truly flawless diamond is exceptionally rare; only a tiny percentage of diamonds worldwide reach these levels. They're investment pieces, often chosen for their rarity as much as their beauty.
How to Choose Your Diamond Clarity Level
Know Your Budget: Be honest about what you want to spend. This influences everything else.
Decide Your Priority: Are you optimizing for absolute visual perfection, the best value, or a balance of both?
Consider Stone Size: Smaller diamonds (under 1 carat) can go lower in clarity without visibility issues. Larger diamonds (2+ carats) benefit from slightly higher clarity.
Think About Your Setting: Solitaire settings show off the stone, so slightly higher clarity is smart. Halo and side-stone settings draw the eye away, so lower clarity works beautifully. Layering pieces don't need perfect clarity.
Look at the Actual Stone: Always examine the stone if possible, or ask for detailed photos. Your eye is the final judge. What the grader says matters, but what you see matters more.

Frequently Asked Questions
Q. Can I see the difference between VS1 and VS2 with my naked eye?
Not unless you're trained to look for it under magnification. Honestly? Almost never. Both grades are eye-clean and look identical when worn.
Q. Is SI1 really eye-clean?
Yes, in the vast majority of cases. SI1 is our sweet spot recommendation because you get beauty and value without compromise.
Q. Do I need GIA certification?
We think it's worth it. GIA is the global standard, and certification gives you confidence in what you're buying. It matters, especially for fine jewelry you'll cherish forever.
Q. Is a VS2 diamond always better than an SI1?
Not automatically. An eye-clean SI1 might actually be a better value. Better depends on your priorities and what you actually see.
Q. What if my diamond shows an inclusion I didn't expect?
This is rare with certified stones. If it happens, talk to your jeweler. We're transparent about what you're getting, and we want you to feel confident.
Q. How does diamond clarity affect price?
It's one of the 4Cs, so clarity impacts cost. But the jump between SI1 and VS1 is usually 15-25%, not double the price. Smart shopping means understanding where that money goes.
