VS1 vs VS2 Clarity
VS1 (Very Slightly Included 1) and VS2 (Very Slightly Included 2) are two of the most popular clarity grades for engagement ring diamonds. Both are considered "eye-clean" — meaning inclusions are not visible to the naked eye.
The difference between VS1 and VS2 lies in the size, number, and position of inclusions visible under 10x magnification. Understanding this difference helps you decide whether the VS1 premium is worthwhile.
| Feature | VS1 | VS2 |
|---|---|---|
| Inclusions Under 10x | Minor — difficult to find | Minor — somewhat easier to find |
| Eye-Clean | Always eye-clean | Almost always eye-clean (99%+ in brilliant cuts) |
| Price Premium | 10–15% more than VS2 | Base price — best value in the VS range |
| Best For | Step cuts (emerald, Asscher) where inclusions are more visible | Brilliant cuts (round, oval, cushion) where facets mask inclusions |
| Resale | Slightly better resale value | Strong resale — most popular clarity grade |
The Practical Difference
In practice, the difference between VS1 and VS2 is invisible to the naked eye. A trained gemmologist examining the diamond under 10x magnification will find inclusions slightly more readily in a VS2 than a VS1, but neither grade will show inclusions to someone wearing the diamond on their hand.
The 10–15% price premium for VS1 over VS2 buys quality that is only detectable under laboratory conditions. For most buyers, this is not a meaningful visual improvement.
When VS1 Matters
There is one scenario where VS1 genuinely matters: step-cut diamonds (emerald and Asscher cuts). These shapes have large, open facets that act like windows into the diamond, making inclusions more visible than in brilliant cuts. For step cuts, VS1 provides an extra margin of safety.
VS1 also makes sense for buyers who want the peace of mind of knowing their diamond is closer to the flawless end of the spectrum — even if the difference is not visible.
Our Verdict
For brilliant cuts (round, oval, cushion, pear), VS2 offers the best value — eye-clean with no visible difference from VS1. For step cuts (emerald, Asscher), consider VS1 for the extra safety margin. The 10–15% savings from choosing VS2 can fund a meaningful upgrade in carat weight.
Frequently Asked Questions
Can you see the difference between VS1 and VS2 with the naked eye?
No. Both VS1 and VS2 are eye-clean grades — inclusions are not visible without magnification. The difference is only detectable by a gemmologist using a 10x loupe or microscope.
Is VS2 safe for a 2 carat diamond?
Yes, in most cases. Larger diamonds can make inclusions slightly more visible, but VS2 in a brilliant cut (round, oval, cushion) is virtually always eye-clean at 2 carats. For a 2 carat emerald or Asscher cut, VS1 is the safer choice.
