Slightly Included Diamond Clarity (Si)
When it comes to diamond quality, one of the most important factors to consider is the diamond's clarity. Clarity refers to the presence of internal and external characteristics, known as inclusions and blemishes, that are present in a diamond.

Slightly Included (SI) diamonds are diamonds that have inclusions and blemishes that are visible under 10x magnification. These inclusions and blemishes are not visible to the naked eye and do not affect the diamond's overall brilliance or fire. SI diamonds are a great option for those looking for a high-quality diamond at a more affordable price point.

It's important to note that not all SI diamonds are created equal. The position, size, and number of inclusions and blemishes can vary greatly from diamond to diamond. Some SI diamonds may have only a few small inclusions that are not visible to the naked eye, while others may have more visible inclusions that are more noticeable. It's important to carefully inspect an SI diamond under magnification to ensure that you are getting the best quality diamond for your budget.

When purchasing an SI diamond, it's important to consider the diamond's cut, color, and carat weight as well. These factors will also affect the diamond's overall appearance and value. A well-cut SI diamond with a high color grade and a large carat weight will still be a beautiful and valuable diamond.

These diamonds have inclusions and blemishes that are visible under 10x magnification but not visible to the naked eye, and do not affect the diamond's overall brilliance or fire. Here at Clairamor, we recommend that you carefully inspect both the diamond and the GIA inclusion plot. Viewing the diamond plot will show you where to look to find the inclusions, this can be helpful for first time viewing to tell if the diamond is up to your standards.

Slightly Included (Si) Compared to Very Slightly Included (VS)?
When comparing Slightly Included (SI) diamonds to Very Slightly Included (VSI) diamonds, it's important to note that the difference in clarity grade is quite subtle. Both SI and VSI diamonds have inclusions and blemishes that are not visible to the naked eye, but the inclusions in a VSI diamond are much harder to spot even under 10x magnification.

The main difference between SI and VSI diamonds is the visibility and number of inclusions. SI diamonds have inclusions that are visible under 10x magnification, while VSI diamonds have inclusions that are extremely difficult to spot even under 10x magnification. VSI diamonds are considered to have a higher clarity grade than SI diamonds.

In terms of price, VSI diamonds are generally more expensive than SI diamonds. However, the price difference between the two can vary depending on the quality of the diamonds. A well-cut, high-color VSI diamond with a large carat weight will be more expensive than a poorly cut, low-color SI diamond with a small carat weight.

In summary, the main difference between Slightly Included (SI) and Very Slightly Included (VSI) diamonds is the visibility and number of inclusions. VSI diamonds have inclusions that are extremely difficult to spot even under 10x magnification and are considered to have a higher clarity grade than SI diamonds, which have inclusions that are visible under 10x magnification. VSI diamonds are generally more expensive than SI diamonds, but the price difference can vary depending on the quality of the diamonds. It's important to consider the diamond's cut, color, and carat weight as well as its clarity grade.
