VS Diamond: Why Very Slightly Included Is the Best Value Clarity Grade

What Is a VS Diamond?

VS stands for Very Slightly Included — the fourth tier on the GIA diamond clarity scale, below Flawless, Internally Flawless, and VVS. VS diamonds contain minor inclusions that are difficult to see under 10x magnification and completely invisible to the naked eye. They are, in the view of most experienced diamond buyers and gemologists, the sweet spot of the clarity scale — offering genuine purity at a price that makes sense.

The VS grade is divided into two sub-grades: VS1 and VS2. VS1 inclusions are harder to detect than VS2, typically smaller or more favorably positioned.

What Inclusions Are Found in VS Diamonds?

VS inclusions are minor but more varied than VVS characteristics. Common inclusion types at this grade include:

• Crystals: Small mineral crystals trapped within the diamond during formation — may appear as tiny dots or shapes under magnification
• Feathers: Small fractures or cleavages, typically minor and posing no structural concern at VS grade
• Clouds: Groups of microscopic pinpoints that appear as a hazy area under magnification
• Needles: Thin elongated crystals
• Indented naturals: Small portions of the original rough diamond surface that extend slightly into the stone

In VS1, these characteristics are typically small, few, and positioned in less visible areas. In VS2, they may be slightly larger or more centrally located — but still require magnification to detect.

VS1 vs VS2: Which Should You Choose?

• VS1: Inclusions are difficult to see under 10x magnification. Completely eye-clean in all cases. Slightly more expensive than VS2.
• VS2: Inclusions are somewhat easier to see under 10x magnification but still require effort. Completely eye-clean in virtually all cases for round brilliants. Offers better value than VS1 with minimal practical difference.

Recommendation: For round brilliant diamonds, VS2 is typically the better value. For step-cut diamonds (emerald, Asscher), VS1 provides a more comfortable margin of safety. Always evaluate the specific stone rather than relying solely on the grade.

Are VS Diamonds Eye-Clean?

Yes — in virtually all cases. VS1 diamonds are always eye-clean. VS2 diamonds are eye-clean in the vast majority of cases, with rare exceptions in step-cut shapes or very large carat weights where inclusions may be slightly more visible.

For round brilliant diamonds, VS2 is a reliable eye-clean grade. For fancy shapes and step cuts, VS1 provides greater assurance.

VS vs. VVS: The Value Case

This comparison makes the case for VS clarity most clearly:

• VVS1: Extremely difficult to see under 10x magnification. Completely eye-clean. Premium price.
• VS1: Difficult to see under 10x magnification. Completely eye-clean. 15–25% less expensive than VVS1.
• Visible difference: None to the naked eye.

The money saved by choosing VS1 over VVS1 on a $8,000 diamond — potentially $1,200–2,000 — can be invested in a better cut grade, larger carat weight, or higher color. All of these have visible impact. The clarity upgrade does not.

VS vs. SI: Where the Line Is Drawn

VS and SI are separated by a meaningful practical threshold:

• VS2: Always requires magnification to detect inclusions. Eye-clean.
• SI1: Usually eye-clean, but requires careful evaluation of the specific stone.
• SI2: May have inclusions visible to the naked eye.

For buyers who want certainty of eye-cleanliness without careful stone-by-stone evaluation, VS2 is the reliable minimum. SI1 can offer excellent value but requires more due diligence.

The Best Use of VS Clarity by Diamond Shape

• Round brilliant: VS2 is the recommended minimum for confident eye-cleanliness. VS1 provides extra assurance.
• Oval, cushion, pear, radiant: VS1–VS2 is the recommended range. These shapes are moderately forgiving.
• Emerald, Asscher (step cuts): VS1 is strongly recommended. The open facet structure makes inclusions more visible than in brilliant cuts.
• Princess cut: VS2 is typically sufficient. The brilliant-style faceting masks inclusions reasonably well.

The Clarity of Intention

In crystal healing traditions, VS clarity diamonds occupy a meaningful place on the spectrum of purity. They are stones that have been formed with great care — their minor inclusions are the natural signatures of their geological journey, present but unobtrusive, like the subtle marks of experience on a wise and beautiful face. A VS diamond is not trying to be flawless; it simply is what it is, beautifully and authentically. For many practitioners, this honest clarity — pure enough to transmit energy freely, real enough to carry a story — is more resonant than the abstract perfection of a Flawless stone.

Final Thoughts

VS clarity — particularly VS1 and VS2 — represents the best value on the GIA clarity scale for most buyers. Eye-clean, beautiful, and significantly more affordable than VVS and FL grades, VS diamonds deliver genuine purity without the premium for rarity you can't see. For most round brilliant diamonds, VS2 is the recommended starting point. For step cuts and larger stones, VS1 provides the right margin of safety.
