When buying a diamond, you’ll often come across terms like VS, VVS, and SI. These abbreviations refer to diamond clarity grades, one of the important factors used to evaluate a diamond’s quality.
For many buyers, clarity grades can seem confusing. But once you understand what these terms mean, choosing the right diamond becomes much easier.
In this guide, we’ll explain VS, VVS, and SI clarity grades in simple terms, what they mean for appearance, and how they affect the value of a diamond.

What Is Diamond Clarity?
Diamond clarity measures the presence of internal inclusions and external blemishes in a diamond.
These tiny natural characteristics form during the diamond’s creation process.
Clarity grading evaluates:
• The number of inclusions
• Their size
• Their position within the diamond
• Their visibility under magnification
Most inclusions are extremely small and invisible to the naked eye.
Understanding clarity helps buyers balance beauty and value when choosing a diamond.

The Diamond Clarity Scale
Diamond clarity is graded on a standard scale used by gemological laboratories such as GIA and IGI.
The scale typically includes:
FL – Flawless
IF – Internally Flawless
VVS1 / VVS2 – Very Very Slightly Included
VS1 / VS2 – Very Slightly Included
SI1 / SI2 – Slightly Included
I1 / I2 / I3 – Included
Among these, VVS, VS, and SI are the clarity grades most commonly seen in jewellery.
What Is VVS in Diamonds?
VVS stands for “Very Very Slightly Included.”
Diamonds in this category have extremely tiny inclusions that are very difficult to see, even under 10x magnification.
VVS Grades
• VVS1 – Inclusions are extremely small and very hard to detect
• VVS2 – Inclusions are still extremely small but slightly easier to locate under magnification
Key Characteristics
✔ Exceptional clarity
✔ Very high rarity
✔ Usually invisible to the naked eye
Because of their rarity, VVS diamonds tend to be more expensive.
However, in everyday jewellery, many buyers find that slightly lower clarity grades can look just as beautiful.
What Is VS in Diamonds?
VS stands for “Very Slightly Included.”
VS diamonds have small inclusions that are visible under magnification but usually not visible to the naked eye.
VS Grades
• VS1 – Inclusions are very small and difficult to see under magnification
• VS2 – Inclusions are slightly easier to detect under magnification
Key Characteristics
✔ Excellent clarity
✔ Inclusions typically invisible without magnification
✔ Popular balance between quality and value
Many jewellery experts recommend VS clarity diamonds because they appear clean while remaining more affordable than VVS diamonds.

What Is SI in Diamonds?
SI stands for “Slightly Included.”
SI diamonds contain inclusions that are noticeable under magnification and sometimes visible to the naked eye depending on the stone.
SI Grades
• SI1 – Inclusions may be visible under magnification but are often not noticeable to the naked eye
• SI2 – Inclusions are more noticeable and may sometimes be visible without magnification
Key Characteristics
✔ More affordable than VS or VVS
✔ Good value for buyers prioritising carat size
✔ Some stones may show inclusions depending on placement
Well-selected SI1 diamonds can still appear very beautiful in jewellery.
Visual Difference Between VVS, VS, and SI
For most buyers, the visible difference between these clarity grades is very small without magnification.
| Clarity Grade | Inclusion Visibility | Price Range |
|---|---|---|
| VVS | Extremely tiny inclusions, almost impossible to see | Highest |
| VS | Very small inclusions, usually invisible to naked eye | Moderate |
| SI | Small inclusions, sometimes visible | More affordable |
Because differences are subtle, many buyers choose VS or SI1 diamonds for the best balance between appearance and price.
What Clarity Grade Should You Choose?
The best clarity grade depends on your priorities.
Choose VVS If You Want
✔ Maximum purity
✔ High rarity
✔ Premium quality diamonds
Choose VS If You Want
✔ Excellent clarity
✔ Diamonds that appear clean
✔ Strong balance between quality and price
Choose SI If You Want
✔ Larger carat size within budget
✔ Good value
✔ Diamonds that still look attractive
Most jewellery experts consider VS clarity diamonds the ideal balance for everyday jewellery.

Does Clarity Affect Sparkle?
Clarity has less impact on sparkle than cut quality.
Sparkle mainly depends on how well the diamond is cut and how it reflects light.
A well-cut VS or SI diamond can often appear more brilliant than a poorly cut VVS diamond.
That’s why experienced jewellers recommend prioritising cut quality first, followed by clarity.
Final Thought
Understanding diamond clarity doesn’t have to be complicated.
VVS, VS, and SI simply describe how visible natural inclusions are inside a diamond.
For most buyers:
• VVS diamonds offer exceptional purity
• VS diamonds provide excellent clarity and value
• SI diamonds offer affordability and larger size options
By balancing clarity with cut, colour, and carat, you can choose a diamond that delivers both beauty and value.
