? The G.I.A. Grading Scale
The GIA grading scale is the ideal measurement method used by the Gemological Institute of America used for checking clarity and quality of stones. According to Gemological Institute of America, VS is the fourth highest rated clarity level for diamonds. It stands for Very Slightly included and the inclusions in VS lenses is very small, almost avoidable. The inclusions are so small that they are not even visible to the bare eyes. They can only be observed when looked through a microscope.
The clarity of VS quality stones is unquestionable. The inclusions in these rings can only be seen when looked through a loop or a microscope. However, even with these instruments, it is hard to make out the inclusions until they are very close to the upper surface. Sometimes, there are hardly any inclusions visible.
? VS Clarity or Other Clarity Grades?
Starting from the lower, other than VS clarity grade, there are SI and I quality grades. SI is slightly Included and I is Included. Compared to these, VS quality sapphire diamond rings or diamond cocktail rings are shinier, have more brilliance and is more ideal as well. The inclusions in others, though not visible very often but tend to diminish the shine and brilliance of the diamond. Thus, VS clarity stones are the perfect choice.
Talking of the higher quality grades, there are three better clarity grades as compared to VS, namely VVS (Very Very Slightly Included), IF (Internally Flawless) and (Flawless). The only difference between the three can be made out when looked through the microscope or loupe. They look very much alike with naked eyes and same goes for their clarity and shine too. Even though they look alike, the price of these three clarity graded stones is higher than the VS stones since they are a bit more inclusion free.
When buying a diamond ring or any other diamond jewelry, check them all thoroughly and see to it that they look good when worn too. Though the inclusions are not visible to the naked eyes at all with these stones, it is advisable to go for the VS clarity stones since they are economical and inclusion free to some extent as well. All others would look more or less the same, but with greater rate or with bigger and more prominent inclusions. VS clarity stones are mediocre and an ideal choice for a ring or a jewelry piece made totally out of diamond.
