Looking to know which is better between SI1 vs VS1?
You’re at the right place!
This is our comparison of the SI1 vs VS1.
In this article, I have reviewed both diamond clarity in-depth and will fully explain to you their differences and which one is better.
Let’s get started with an in-depth look at what sets these diamond clarity apart.
What’s The Difference Between SI1 vs VS1?
Understanding SI1 Diamond Clarity: A Window into its World
SI1 diamonds, also known as slightly included diamonds, offer a fascinating journey into a world of intricate inclusions. These inclusions are the internal characteristics that can be found within the diamond. They may include crystals, feathers, cavities, or needles, each adding its own unique touch of character to the diamond’s allure. While some SI1 diamonds may have only a single inclusion, others may display a charming array.
It’s important to note that the visibility, size, and position of these inclusions can vary from one SI1 diamond to another. Some inclusions may be visible to the naked eye, while others require the aid of a jeweler’s loupe for detection. These inclusions contribute to the individuality of the diamond, making each SI1 diamond a distinct and captivating choice.
To truly appreciate the beauty of an SI1 diamond, it’s recommended to observe it from different angles, allowing the light to interact with the inclusions and create mesmerizing patterns. A high-resolution 360-degree image can provide a detailed view of the diamond, allowing you to explore its unique features.
VS1 Diamond Clarity: Discovering Subtle Perfection
VS1 diamonds, or very slightly included diamonds, are renowned for their exceptional clarity. These diamonds possess inclusions that are barely perceptible, even under 10x magnification. The inclusions within a VS1 diamond are typically small and discreet, such as delicate etch channels, feathers, or naturals. They add a touch of uniqueness to the diamond without compromising its overall brilliance and sparkle.
When compared side by side with higher clarity grades, such as VVS2 or VS2, the differences in visual appearance are nearly imperceptible to the naked eye. VS1 diamonds offer a balance between exceptional clarity and cost, making them an excellent choice for those seeking a diamond with refined elegance.
To appreciate the subtle beauty of a VS1 diamond, it’s recommended to examine its clarity plot. A clarity plot is a visual representation of the diamond’s inclusions, allowing you to understand their size, location, and overall impact on the diamond’s appearance.
When it comes to diamond clarity, understanding the differences between SI1 (slightly included) and VS1 (very slightly included) diamonds is essential. These two grades represent distinct levels of clarity, each with its own characteristics and visual appeal. Let’s delve into the details and explore the key distinctions between SI1 and VS1 diamonds.
1. Visibility of Inclusions:
One of the primary differences between SI1 and VS1 diamonds lies in the visibility of their inclusions. SI1 diamonds typically have more noticeable inclusions compared to VS1 diamonds. While SI1 inclusions may be visible to the naked eye or with slight magnification, VS1 inclusions are often challenging to detect without magnification.
Example:
For instance, let’s consider an SI1 diamond. This 1.02-carat round diamond showcases several black spots scattered across its table, likely resulting from crystalized carbon. These inclusions are visible and may affect the diamond’s overall appearance.
In contrast, a VS1 diamond of similar size may have inclusions that are significantly less visible. Here is a VS1 diamond example that exhibits a crystal and a natural inclusion, both of which are small and inconspicuous.
2. Number and Size of Inclusions:
SI1 diamonds generally have a higher number of inclusions compared to VS1 diamonds. These inclusions can vary in type, size, and distribution within the diamond. In contrast, VS1 diamonds tend to have fewer and smaller inclusions, which have minimal impact on the diamond’s appearance.
Example:
Let’s compare two cushion-cut diamonds—one graded SI1 and the other graded VS1. The SI1 diamond shows five different types of inclusions, including crystals, feathers, cavities, needles, and indented naturals. These inclusions are easily visible and cover the diamond’s table and pavilion.

On the other hand, the VS1 diamond has feather and pinpoint inclusions, which are significantly smaller and barely visible even on the grading report. These minor inclusions have minimal impact on the diamond’s overall appearance and brilliance.
3. Brilliance and Light Performance:
The difference in clarity between SI1 and VS1 diamonds can affect their brilliance and light performance. While both grades can exhibit excellent sparkle, VS1 diamonds generally have better light performance due to their fewer and less noticeable inclusions.
Example:
Consider a princess-cut VS1 diamond. Despite having five types of inclusions, these minor flaws have no obvious impact on the diamond’s appearance. The VS1 diamond exhibits exceptional brilliance and sparkle.

Similarly, an SI1 diamond can also display good brilliance, but the presence of more noticeable inclusions may slightly diminish its sparkle. However, this difference is often negligible and may not be noticeable to the naked eye.
4. Price and Affordability:
As expected, there is a price difference between SI1 and VS1 diamonds. VS1 diamonds typically command a higher price due to their superior clarity and fewer visible inclusions. SI1 diamonds, on the other hand, are generally more affordable while still offering excellent value.
Example:
When comparing prices for round-cut diamonds with similar qualities such as carat weight, cut, and color, an SI1 diamond may cost around $5,000, while a comparable VS1 diamond could range from $6,500 to $7,500. This price difference reflects the higher clarity grade and enhanced visual appeal of the VS1 diamond.
Conclusion:
In summary, understanding the differences between SI1 and VS1 diamond clarity grades is crucial when selecting a diamond. SI1 diamonds typically have more noticeable inclusions, whereas VS1 diamonds boast fewer and less visible flaws. VS1 diamonds tend to exhibit superior light performance and sparkle, making them highly desirable. However, SI1 diamonds offer excellent value for those seeking affordability without compromising too much on clarity.
It’s important to note that diamond clarity is just one of the factors to consider when choosing a diamond. Personal preferences, budget, and other characteristics such as cut, color, and carat weight also play a significant role in finding the perfect diamond for your needs.
