Diamonds whose clarity is ranked SI area unit in style among patrons as these stones area unit loads more cost-effective than higher clarity diamonds. Let’s see what SI clarity suggests that, however, it compares with alternative clarity grades, and once shopping for SI-clarity diamonds may be a smart plan.
SI Clarity and Alternative Grades
SI diamond clarity is that the fifth highest grade within the six-grade scale employed by the G.I.A. (Gemological Institute of America).
Diamonds within the SI clarity vary have inclusions that area unit simple to visualize under magnification.
There is only 1 lower grade than SI which is I (standing for “Included”).

Some of these flaws could also be visible with the eye, however, you may still have a tough time seeing them.
This clarity vary is more divided into 2 sub-grades: SI1 and SI2, with SI1 being the upper-quality grade.
When staring at Associate in Nursing SI-clarity diamond, it’s necessary to conjointly resolve the sub-grade of the stone.
Difference Between SI1 and SI2 Clarity
SI1-clarity diamonds have slight inclusions which will be simply seen beneath magnification. However, these flaws cannot be seen with the eye.
SI2-clarity stones, on the opposite hand, have larger inclusions, a number of which can be visible to the eye, though barely.
When staring at Associate in Nursing SI2 stone from the highest, you always won’t be ready to see flaws; if there area unit any, they must be barely visible at the best.

Is There SI3 Clarity?
Some vendors use the grade SI3 to talk over with diamonds that aren’t adequate to be ranked SI2 however area unit still higher than the stones within the I-clarity vary.
Although there area unit some grading labs that use the SI3 designation, you ought to bear in mind that this grade doesn’t exist on the G.I.A. scale. Diamonds described as SI3 aren’t ranked by the G.I.A., which might presumably grade them as I1-clarity stones.
Although their area unit diamonds that it will be argued that they fall between SI2 and I1, several sellers use the SI3 grade merely to form I1 diamonds sound higher.
So, however, does one apprehend that you simply area unit addressing Associate in Nursing I1 diamond Associate in, not an SI2 stone?
Take a glance at the diamond from the highest. If you’ll be able to clearly see inclusions, then the stone belongs within the I1 category; SI2 diamonds ought to have visible inclusions which will be seen solely from the aspect (with the naked eye); if there area unit ones are visible from the highest, they must be barely noticeable.
How to purchase SI-Clarity Diamonds

We already saw that the distinction between SI1 and SI2 is within the visibility of the failings. As you would possibly guess, these 2 grades conjointly take issue is worth. Associate in Nursing SI1 stone will be many bucks dearer than Associate in Nursing SI2 diamond.
If you wish to avoid wasting cash by shopping for SI2 rather than SI1 clarity, do investigate many alternative SI2 stones and look at them from all sides. Some diamonds during this class have inclusions that area unit a lot of visible, whereas others have flaws which will barely be seen, and you’ll be able to get a stone that appears fairly clean at an honest worth.
It is can jointly necessary to contemplate however the diamond is going to be worn. If it’ll be set during a mounting that may cowl the stone’s sides, then Associate in Nursing SI2 diamond could also be an honest selection as no matter visible flaws it’s on its sides, these inclusions are going to be hidden by the setting anyway.
