Diamond clarity describes the presence of internal characteristics (inclusions) and external characteristics (blemishes) within a diamond. While clarity affects value, it usually has less impact on visible beauty than buyers expect—when the right clarity range is chosen.

How the Diamond Clarity Scale Works
Diamond clarity is graded under 10× magnification using a standardized scale that applies equally to lab-grown and mined diamonds.
- FL / IF: Flawless or Internally Flawless
- VVS1–VVS2: Very, very small inclusions
- VS1–VS2: Very small inclusions (typically eye-clean)
- SI1–SI2: Small inclusions (often visible)
- I1–I3: Included (visible to the naked eye)
In practical terms, most buyers should focus on clarity grades that appear eye-clean in normal viewing—not microscopic perfection.
VS1 vs VS2: What’s the Real Difference?
VS1 Clarity
VS1 diamonds contain very small inclusions that are difficult to locate even under magnification. They:
- Are reliably eye-clean
- Offer strong long-term confidence
- Balance value and visual perfection
This is why VS1 is our preferred clarity standard for worry-free beauty.
VS2 Clarity
VS2 diamonds often appear eye-clean, but inclusions may be slightly easier to locate under magnification.
- Can offer good value when carefully evaluated
- May show inclusions in larger stones
- Require stricter selection standards
Because appearance can vary, VS2 diamonds must be assessed individually to ensure they meet eye-clean expectations.
Why We Avoid SI Clarity in Lab Diamonds
SI clarity diamonds often contain inclusions that may be visible to the naked eye—especially in larger sizes or high-contrast lighting.
In lab-grown diamonds, SI pricing frequently overlaps with VS grades, reducing the value advantage that SI once offered. For this reason, SI clarity is generally avoided in favor of cleaner, more consistent options.
By focusing on VS1+, we eliminate uncertainty and ensure long-term satisfaction.
Does Diamond Size Affect Clarity Visibility?
Yes. As carat size increases, inclusions become easier to see.
- Under 1.00 ct: VS2 may appear eye-clean
- 1.00–2.00 ct: VS1 recommended
- Over 2.00 ct: VS1+ strongly recommended
Cut quality also plays a role. Well-cut diamonds reflect more light, helping inclusions remain less noticeable. Learn more here: How to Choose the Best Lab-Grown Diamond Cut (2026 Buying Guide).
