Summary
Welcome to our sparkling corner of the internet, where we resume our journey through the captivating realm of SI1 diamonds from our previous blog. This time, we will dive deep into exploring the mesmerizing beauty and allure of SI (Slightly Included) diamonds.
What Does SI1 Clarity Mean?
SI1 diamond clarity means the diamond has slight inclusions that are visible under 10x magnification, but generally not visible to the naked eye. SI1 is a specific clarity grade within the diamond grading system.
It stands for Slightly Included 1 and is a term used to describe the level of internal characteristics or inclusions present in a diamond. The clarity grade of a lab diamond refers to the extent to which it has internal or external flaws that can affect its overall appearance and brilliance.
Seeing Clearly: How to Determine Eye Clean SI1 Diamonds

Review the clarity grading system: Familiarize yourself with the diamond clarity grading system, including the “Slightly Included” (SI) category and the subcategory of SI1.
Understand the definition of SI1 clarity: SI1 diamonds have slight inclusions that are visible under 10x magnification to a trained grader. The key here is that these inclusions are generally not easily noticeable to the naked eye.
Look for additional descriptors: When researching or evaluating an SI1 diamond, pay attention to any additional descriptions provided by the jeweler or seller. They may use terms like “eye-clean” or “visually clean” to indicate that the lab diamond appears free from noticeable inclusions when viewed without magnification.
Unlocking the Value: Exploring the Price Range of SI1 Diamond Clarity
SI1 clarity diamond: SI1 diamonds are generally more affordable compared to higher clarity grades. However, the price can still fluctuate depending on other factors.
Diamond G color SI1 clarity: The color grade of a diamond also plays a role in determining its price. A G color diamond, which is considered near colorless, will typically be more expensive than lower color grades.
Diamond color D clarity SI1: Diamonds with a color grade of D are considered the highest grade on the color scale, indicating exceptional colorlessness. When paired with SI1 clarity, the diamond’s price may increase due to the premium associated with a colorless stone.
SI1 diamond price: The si1 diamond price can vary significantly depending on the other characteristics mentioned above. As a general guideline, you can expect SI1 diamonds to range from a few hundred dollars to several thousand dollars per carat, with larger stones commanding higher prices.
Generally, SI1 clarity prices can start from $250 and go up to several thousand dollars.

Why Choose GIA Certified SI1 Clarity Diamonds
Choosing GIA certification guarantees an impartial assessment by industry experts. GIA’s rigorous standards and esteemed reputation enhance the reliability of its certificates. When acquiring an SI1 clarity diamond, the inclusion of a GIA certificate substantiates the stone’s quality and authenticity, instilling confidence in the purchase.
GIA clarity grades, from highest to lowest:
- Flawless (FL)
- Internally Flawless (IF)
- Very Very Small Inclusions (VVS1)
- Very Very Small Inclusions (VVS2)
- Very Small Inclusions 1 (VS1)
- Very Small Inclusions 2 (VS2)
- Small Inclusions 1 (SI1)
- Small Inclusions 2 (SI2)
- Inclusions 1 (I1)
- Inclusions 2 (I2)
- Inclusions 3 (I3)
As you can see, SI1 diamond clarity is closer to the bottom. SI1 diamond is not exactly the best choice when it comes to diamonds. The clarity of a diamond depends mainly on inclusions. The type, cut, size, and amount of inclusions can make any diamond beautiful or unfit for jewelry.
Even a high-clarity diamond might have some imperfections. It’s rare to find a lab diamond without any flaws. So it would be beneficial if you are looking for a diamond that is eye-clean and will look good on your jewelry.
When assessing whether an SI1 diamond is eye-clean or not, it is important to consider the specific characteristics of the stone. Here are some steps to keep in mind.
Crystal Clear Choices: Essential Tips For Buying SI1 Clarity Diamonds
Understand SI1 clarity characteristics: Familiarize yourself with the definition of SI1 clarity and its slight inclusions visible under 10x magnification. Remember that these inclusions are generally not easily noticeable to the naked eye, making SI1 diamonds a popular choice for balancing quality and budget.
Prioritize eye-cleanliness: Look for keywords like “eye-clean” or “visually clean” when searching for an SI1 diamond. These descriptors indicate that the diamond appears free from noticeable inclusions when viewed without magnification. Request detailed images or videos to personally assess the lab grown diamond’s eye-cleanliness.
Consider the color grade: If color is important to you, focus on SI1 diamonds with higher color grades such as G color or even colorless grades like D. This combination of SI1 clarity and a desirable color grade can enhance the overall appearance of the diamond.
Now that you have a better understanding of what to consider when choosing an SI1 diamond, it’s time to embark on your search! Choose diamonds from hundreds of styles on Loosegrowndiamond.
