When shopping for a lab grown diamond, clarity is one of the most important factors affecting appearance and value. Many buyers assume they need the highest possible clarity grade, but in reality, the best clarity for a lab grown diamond is usually the grade that looks flawless to the naked eye without paying for imperfections you cannot actually see.
For most buyers, VS1 or VS2 clarity offers the best balance of beauty, quality, and price. These grades typically appear clean without magnification while costing significantly less than premium flawless grades.
Understanding how clarity works can help you avoid overspending and choose a diamond that looks stunning in real life, not just on a certificate.

What Does Diamond Clarity Mean?
Clarity refers to the number, size, and visibility of internal inclusions and external blemishes within a diamond.
Lab grown diamonds are graded using the same clarity scale as natural diamonds by major certification laboratories such as IGI and GIA. The grading system ranges from Flawless (FL) to Included (I).
Here is a simplified breakdown:
| Clarity Grade | What It Means |
|---|---|
| FL / IF | No visible inclusions under 10x magnification |
| VVS1 / VVS2 | Extremely tiny inclusions that are very difficult to see |
| VS1 / VS2 | Minor inclusions that are difficult to notice |
| SI1 / SI2 | Noticeable inclusions under magnification and sometimes visible to the eye |
| I1 / I2 / I3 | Obvious inclusions that may affect appearance and durability |
In most cases, inclusions in higher clarity grades are impossible to detect without professional magnification tools.

What Is the Best Clarity for a Lab Grown Diamond?
The best clarity grade depends on your priorities, budget, and diamond shape. However, for the majority of buyers, VS1 and VS2 are considered the ideal choices.
These grades provide:
- Excellent visual appearance
- Strong value for money
- Eye clean beauty in most sizes
- Better pricing than premium clarity grades
Many shoppers initially focus on VVS or Flawless diamonds because they sound more impressive. In reality, the visual difference between a VS1 and a VVS1 diamond is usually impossible to detect without magnification.
That means paying significantly more for clarity that does not noticeably improve how the diamond looks when worn.

Why VS1 and VS2 Clarity Offer the Best Value
Lab grown diamonds already provide strong value compared to natural diamonds, so choosing the right clarity grade can maximize savings even further.
VS1 Clarity
VS1 diamonds contain very small inclusions that are extremely difficult to spot, even under magnification.
VS1 is ideal for buyers who want:
- High visual purity
- Excellent certification quality
- Strong long term appearance
- Confidence in larger stones
This grade is especially popular for engagement rings where buyers want premium appearance without paying for VVS pricing.
VS2 Clarity
VS2 clarity is often the sweet spot for smart buyers.
In most lab grown diamonds, VS2 inclusions are still invisible to the naked eye, especially in well cut round diamonds. The price difference compared to VVS grades can be substantial.
VS2 is an excellent option if you want:
- Maximum value
- Eye clean appearance
- Larger carat size within budget
- Strong overall quality
For many people, a larger VS2 diamond will look more impressive than a smaller VVS diamond at the same price.

Is VVS Clarity Worth It?
VVS1 and VVS2 diamonds are exceptionally clean under magnification, but they are not always worth the extra cost for everyday buyers.
The main reason is simple: you usually cannot see the difference without professional tools.
VVS clarity may make sense if you:
- Want ultra premium specifications
- Prefer rare, collector style quality
- Are buying a very large diamond
- Value certificate grades highly
Otherwise, most buyers will get better overall value by choosing VS clarity and prioritizing cut quality or carat size instead.

Should You Avoid SI Clarity Diamonds?
Not necessarily.
Some SI1 lab grown diamonds can still appear eye clean, particularly in smaller sizes or brilliant cuts. However, quality becomes more inconsistent as you move into SI grades.
The risk with SI clarity is that inclusions may become visible in certain lighting conditions or from close viewing distances.
If considering SI1 clarity:
- Review high resolution videos carefully
- Ask whether the diamond is eye clean
- Check inclusion placement
- Avoid dark or centrally located inclusions
SI2 diamonds are generally less recommended for engagement rings because inclusions are more likely to affect appearance.

Does Diamond Shape Affect Clarity Visibility?
Yes. Diamond shape plays a major role in how visible inclusions appear.
Some shapes hide inclusions better than others.
Shapes That Hide Inclusions Well
These brilliant cut shapes reflect more light and help mask inclusions:
- Round Brilliant
- Oval
- Cushion
- Radiant
- Pear
You can often safely choose slightly lower clarity grades in these shapes without affecting visual beauty.
Shapes That Show Inclusions More Easily
Step cut diamonds have larger open facets that make inclusions easier to notice:
- Emerald
- Asscher
For these shapes, many buyers prefer VS1 or higher clarity to maintain a clean appearance.
If you are comparing different shapes, reading a detailed lab diamond clarity guide can help you understand how clarity behaves across cuts.

Does Carat Size Change the Best Clarity Choice?
Yes. Larger diamonds make inclusions easier to see.
For example:
- A 0.75 carat VS2 diamond may look perfectly clean
- A 3 carat VS2 diamond may reveal inclusions more easily
As diamond size increases, buyers often move slightly higher in clarity for peace of mind.
General recommendations:
| Diamond Size | Recommended Clarity |
|---|---|
| Under 1 carat | VS2 or SI1 |
| 1 to 2 carats | VS1 or VS2 |
| Above 2 carats | VS1 or higher |
These are not strict rules, but they are useful guidelines when comparing certified lab diamonds.

Why Cut Quality Matters More Than Clarity
One of the biggest mistakes buyers make is prioritizing clarity over cut quality.
A perfectly cut diamond reflects light beautifully and appears brighter, more lively, and more impressive. A poorly cut diamond can look dull even with flawless clarity.
In most situations:
- Excellent cut + VS2 clarity looks better than
- Poor cut + VVS1 clarity
When balancing the 4Cs, cut quality should usually come first.
After securing an excellent cut, focus on finding an eye clean clarity grade that fits your budget.

How to Choose the Best Clarity Without Overspending
The smartest way to buy a lab grown diamond is to focus on visible beauty rather than chasing the highest certificate grades.
Here are practical buying tips that help maximize value.
Prioritize Eye Clean Appearance
If inclusions cannot be seen without magnification, paying more for higher clarity often adds little visual benefit.
Match Clarity to Shape
Brilliant cuts can tolerate lower clarity grades more easily than step cuts.
Review Videos Carefully
Always inspect magnified videos and certificates when comparing loose lab diamonds.
Avoid Paying for Invisible Perfection
Flawless and VVS diamonds sound impressive, but most buyers will never see the difference in everyday wear.
Balance the 4Cs
A slightly lower clarity grade may allow you to upgrade:
- Carat size
- Cut quality
- Color grade
- Overall ring design
That tradeoff often creates a more visually impressive diamond.

Common Misconceptions About Diamond Clarity
Higher Clarity Always Looks Better
Not necessarily. Once a diamond appears eye clean, higher clarity grades often provide little visible improvement.
Flawless Diamonds Sparkle More
Sparkle is primarily determined by cut quality, not clarity.
Lab Grown Diamonds Have Worse Clarity
Many lab grown diamonds actually have excellent clarity because they are created in controlled environments.
You Need VVS for an Engagement Ring
Most engagement rings look stunning with VS clarity.

Final Thoughts

By understanding how clarity interacts with shape, cut, and carat size, you can compare certified lab diamonds more confidently and choose a stone that delivers both beauty and smart value.
