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

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.

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.
