What Is SI Diamond Clarity?

SI diamond clarity refers to a specific grade of clarity used to describe the internal characteristics or inclusions present in a diamond whether the diamond is natural or lab-grown. The term “SI” stands for “Slightly Included,” representing a range within the diamond clarity scale. Inclusions in SI diamonds can include small crystals, clouds, feathers, or pinpoints. These imperfections do not significantly impact the diamond’s structural integrity or brilliance. However, they can affect the diamond’s overall appearance and value compared to higher clarity grades like VVS (Very, Very Slightly Included) or IF (Internally Flawless).

Customers choose diamonds with a clarity rating of SI since they are much more affordable than those with greater clarity. The SI grade is divided into two sub-categories: SI1 and SI2. 

Learn more about SI1 and SI2 clarity in lab-grown diamonds

There are two sub-categories in SI clarity of the grown diamond, which are SI1 and SI2. With SI1 clarity of man made diamonds, the inclusion is not visible to the naked eyes and would require a magnification lens to spot them. While in SI2 graded lab created diamonds, some inclusions are visible by naked eyes, so it becomes imperative for a consumer to check and chose while selecting SI2 clarity lab made diamond. 

SI1 and SI2 Diamonds | Lab Grown Diamonds SI Price

One should prefer a diamond with smaller inclusions over the number of inclusions in a single lab diamond because smaller impurities won’t be visible with normal vision. Sometimes visibility of impurities depends on the angle you are inspecting SI2 clarity diamonds; If you look from the top, you might not see any inclusion, but if you are examining it from the sides, the inclusion will be visible in most cases.

Difference Between SI1 and SI2 Clarity

The main difference between SI1 (Slightly Included 1) and SI2 (Slightly Included 2) diamond clarity grades lies in the visibility and characteristics of the inclusions within the diamond:

SI1 Diamonds:

  • Have slightly more noticeable inclusions than those in the higher VS (Very Slightly Included) grades.
  • The inclusions are typically still not easily visible to the naked eye.
  • SI1 is the highest SI clarity grade.

SI2 Diamonds:

  • Have more prominent inclusions than SI1 diamonds.
  • The inclusions are likely to be visible to the naked eye, though they may still appear faint.
  • SI2 is the lowest of the two SI clarity grades.

Is there s13 clarity?

The term “SI3 clarity” is not a standard clarity grade recognized by major gemological laboratories like GIA (Gemological Institute of America) or AGS (American Gem Society). The internationally recognized clarity scale used in the diamond industry typically ranges from Flawless (FL) to Included (I) and includes subdivisions such as Internally Flawless (IF), Very Very Slightly Included (VVS), Very Slightly Included (VS), Slightly Included (SI), and Included (I).

The term “SI3” may occasionally be used colloquially by retailers or within certain diamond markets to describe diamonds that fall between SI2 and I1 (Included 1) in terms of clarity. These diamonds may have inclusions that are more visible than typical SI2 diamonds but are not quite as included as I1 diamonds. However, it’s important to note that the SI3 designation is not recognized or graded by major gemological laboratories.

How to purchase SI-Clarity Diamonds

Here are some tips for purchasing SI (Slightly Included) clarity diamonds:

  1. Determine your budget and priorities: SI diamonds can offer significant cost savings compared to higher clarity grades like VVS or IF.
  2. Consider the diamond’s cut quality: An excellent cut can help mask the appearance of inclusions in SI diamonds by maximizing brilliance and fire. Prioritize well-cut SI diamonds over poorly cut clarity stones.
  3. Don’t compromise on other factors: While saving on clarity, don’t sacrifice too much on other important factors like cut, color, and carat weight, as these also impact the diamond’s beauty.

With careful selection and realistic expectations, an eye-clean SI diamond can offer excellent value while still appearing beautiful.
