VS Diamond Quality – Complete 2026 Guide
What Is VS Diamond Quality?
VS stands for “Very Slightly Included” – one of the most sought-after grades on the GIA diamond clarity scale. A VS diamond contains minor inclusions that a trained gemologist can find only with effort under 10x magnification, which means that to the naked eye, these stones look virtually flawless.
The VS category is split into two grades: VS1 (fewer, smaller, more peripheral inclusions) and VS2 (slightly larger or more central inclusions that are still very difficult to detect). Industry data suggests roughly 95% of VS1 diamonds and about 85% of VS2 diamonds appear completely eye-clean, which is why gemologists consistently call VS the “sweet spot” of the clarity scale – near-perfect beauty without the steep premium of VVS or Flawless grades.
At OM Jewels Inc, VS clarity is the grade we recommend most often to jewelers, designers, and retail buyers who want maximum brilliance per dollar. This guide explains exactly what VS quality means, how VS1 compares to VS2, current 2026 pricing, and how to choose the right stone.
Where VS Sits on the GIA Clarity Scale
The Gemological Institute of America (GIA) developed the clarity scale in the 1950s, and it remains the global standard. It runs from Flawless to Included across 11 grades. VS1 and VS2 sit comfortably in the upper-middle, below the microscopic-perfection grades and above grades, where inclusions may become visible.
| Grade | Meaning | Eye-Clean? | Value Position |
| FL / IF | Flawless / Internally Flawless | Always | Extreme premium; collector tier |
| VVS1 / VVS2 | Very, Very Slightly Included | Always | High premium; invisible benefit |
| VS1 | Very Slightly Included 1 | ~95% of stones | Best balance of purity & price |
| VS2 | Very Slightly Included 2 | ~85% of stones | Best overall value grade |
| SI1 / SI2 | Slightly Included | Sometimes | Budget: inspect carefully |
| I1–I3 | Included | Rarely | Visible flaws; not recommended |
VS1 vs VS2: The Key Differences
Both grades are excellent, but they are graded on the size, number, position, nature, and relief of inclusions. VS1 inclusions tend to be peripheral and take even an expert several seconds to locate under a loupe. VS2 inclusions may be slightly larger, more numerous, or closer to the center of the table facet – yet in most stones, they remain invisible without magnification.
| Factor | VS1 | VS2 |
| Inclusion visibility (10x loupe) | Very difficult to find | Slightly easier to find |
| Typical inclusion position | Edges/pavilion (peripheral) | May sit nearer the center |
| Eye-clean rate | ≈ 95% | ≈ 85% |
| Price vs. the other grade | Up to 10–25% higher per carat | More budget-friendly |
| Best for | 2ct+ stones, step cuts, investment | Brilliant cuts, max size per budget |
| Resale / appreciation | Stronger (rarer grade) | Good |
E vs F vs G Color Diamond Guide
VS Diamond Prices in 2026
Clarity is only one of the diamond 4Cs, so prices vary with carat, color, cut, shape, and whether the diamond is natural or lab-grown. As a current benchmark, a 1-carat round natural diamond in F–G color typically runs about $5,000–$7,000 in VS1 and roughly $4,500–$6,200 in VS2. The gap between the two grades can reach 10–25% per carat and widens as carat weight increases.
| Stone (Round, G color, Excellent cut) | VS1 (approx.) | VS2 (approx.) |
| 0.50 ct natural | $1,300 – $1,900 | $1,150 – $1,700 |
| 1.00 ct natural | $5,000 – $6,800 | $4,500 – $6,200 |
| 2.00 ct natural | $11,000 – $16,000 | $9,500 – $14,000 |
| 1.00 ct lab-grown | $700 – $1,300 | $600 – $1,100 |
| 2.00 ct lab-grown | $1,500 – $2,800 | $1,300 – $2,400 |
Lab-grown VS diamonds have made high clarity dramatically more accessible: the same VS grade often costs 70–85% less than its natural counterpart, letting buyers upgrade color, carat, or setting instead.
How to Choose Between VS1 and VS2
- Choose VS1 if: You’re buying 2 carats or more, selecting a step cut (emerald or Asscher) whose long open facets showcase clarity, or you want the stronger long-term value of the rarer grade.
- Choose VS2 if: You’re buying a round brilliant, oval, cushion, or pear shapes whose sparkle naturally hides inclusions – and you’d rather put the savings toward a larger stone or better color.
- Check the plot: Always review the inclusion diagram on the GIA or IGI report. A VS2 with inclusions near the edge (hideable under a prong) can outperform a VS1 with a centered inclusion.
- Prioritize cut first: An excellent-cut VS2 will look more beautiful than a Very Good-cut VVS. Cut drives sparkle; clarity only removes distractions.
- View real imagery: Insist on HD photos or video of the exact stone – never buy on the grade alone.

Frequently Asked Questions
Is the VS diamond quality good?
Yes – VS is widely considered the best quality-to-price ratio on the clarity scale. The stones look identical to far more expensive VVS diamonds in everyday wear.
Can you see inclusions in a VS diamond?
Rarely with the naked eye. Inclusions in VS diamonds are defined by being difficult to locate even under 10x magnification.
Is VS1 worth the premium over VS2?
If the price gap is small, VS1 is the safer, more appreciable buy – especially for large or step-cut stones. If the gap is large, an eye-clean VS2 delivers identical real-world beauty for less.
Do lab-grown VS diamonds differ from natural VS diamonds?
The grading standard is identical. Lab-grown diamonds also form with inclusions, so a lab-grown VS1 is judged by the same criteria as a natural VS1 – at a fraction of the price.
Which certificates should I trust?
GIA for natural diamonds; GIA or IGI for lab-grown. Every diamond sold by OM Jewels Inc ships with tamper-proof GIA or IGI certification.
