When buying diamonds, many people hesitate between VS1 and VS2 because both belong to the high clarity group, the price difference is not too large but significantly affects the value of the stone.
So, what is the difference between VS1 and VS2 diamonds? Is it worth paying more for VS1? The article below will help you understand clearly from the perspective of a diamond appraisal expert.
What is VS clarity grade?
VS (Very Slightly Included) is a clarity grade of diamond, indicating small inclusions. VS is behind FL, IF, VVS clarity grades on the GIA scale.
According to the GIA clarity grading system, the VS group is divided into:
- VS1 (Very Slightly Included 1)
- VS2 (Very Slightly Included 2)
These are two grades between VVS (Very Very Slightly Included) and SI (Slightly Included) on an 11-grade clarity scale.
The higher the grade, the fewer inclusions and the greater the value of the diamond.

GIA clarity grading scale
What is a VS1 diamond?
A VS1 diamond contains very small inclusions, extremely difficult to detect even with a 10x magnification loupe – the standard GIA uses for grading.
Common characteristics:
- Inclusions are not visible to the naked eye.
- Inclusions are often located near the edge of the stone.
- Little impact on brilliance and light reflection.
Common types of inclusions include:
- Crystal
- Needle
- Small Feather
- Pinpoint
These are all very small inclusions and do not affect the durability of the diamond under normal use conditions.
What is a VS2 diamond?
VS2 also belongs to the Very Slightly Included group, but the number or size of inclusions will be greater than VS1.
Characteristics:
- Still almost invisible to the naked eye in most stones under 1 carat.
- Easier to observe under a 10x loupe.
- Some larger stones or step cuts (Emerald, Asscher) may show inclusions if observed closely.
The important thing is that not all VS2 stones are the same.
Some VS2 stones are completely "eye-clean" (no inclusions visible to the naked eye), while others have inclusions located directly under the table, making them easier for observers to notice.
Comparison table of VS1 and VS2 diamonds
The biggest practical difference between VS1 and VS2 is not in their outward appearance when worn, but in the defect plotting on the GIA report and the ownership cost.
Here is a technical analysis table to give you a visual perspective:
| Criterion | VS1 Grading | VS2 Grading |
| Size of inclusions | Microscopic, pinpoint, or small cloud. | Slightly larger, may include small feathers or crystals. |
| Location on stone diagram | Often located on the outer edge or covered by the setting. | Tend to be located near or directly under the main table. |
| Eye-clean level | 100% for all carat sizes. | 95% for stones under 2.0 Carats. Larger stones require careful inspection. |
| Market price variation | 5% to 15% higher than VS2 (depending on color category). | Cost-saving, easy budget optimization. |
| Natural rarity | Less rare than VVS but significantly rarer than VS2. | More abundant natural mining output. |

FAQ - Frequently Asked Questions
Are inclusions visible to the naked eye in VS2 diamonds?
Mostly not, especially for diamonds under 1 carat. However, in larger stones or step cuts, if inclusions are near the table, they may still be noticeable upon close observation.
Is VS1 more worth it than VS2?
If you prioritize perfection or are buying a large diamond, VS1 is a reasonable choice. Conversely, if you want to optimize your budget while ensuring eye appeal, VS2 is often a more economical choice.
Is it worth upgrading from VS2 to VVS?
In most cases, it is unnecessary. The difference between VS and VVS is very difficult to discern with the naked eye, while the price can increase significantly.
VS1 and VS2 both belong to the high clarity diamond group, suitable for fine jewelry and engagement rings. VS1 offers higher clarity, suitable for those who prioritize perfection or long-term investment. VS2 is a balanced choice between quality and cost, especially when the stone meets the eye-clean standard.
