The second change made to the grading system was the introduction of the i 3 grade.
Vvs lab diamonds a grade.
Nearly all diamonds lab grown and mined alike have inclusions.
Vvs1 clarity grade diamond dubbed as very very slightly included vvs1 diamonds have inclusions that only a trained gemologist can detect under a 10x loupe.
A diamond with eye visible inclusions would not receive a clarity grade of vvs 1 or vvs 2.
This change was made in response to a growing number of diamonds of very low clarity being cut.
Vvs diamonds are the second best grade for diamond clarity but don t let this fool you.
Vvs diamonds are found in the higher tier of the clarity grading scale and are often sold as top quality diamonds.
The flaws in this grade are so slight that even an expert can find it difficult to view imperfections in 10x magnification.
On the diamond clarity scale vvs1 diamonds are a grade higher than vvs2 diamonds and a grade lower than internally flawless if diamonds.
Vvs2 diamonds are more included than vvs1 diamonds and usually cost slightly less.
However gia and ags stand out as they have a global reputation in having the highest and the most consistent grading system.
Inclusion location is part of the information that decides whether a diamond is classified vvs1 or vvs2.
Only under a powerful microscope can trained professionals spot inclusions in vvs1s.
These are imperfections that contribute to the overall uniqueness of a diamond and commonly consist of crystals feathers clouds and trace minerals in mined diamonds and trace metals in lab grown diamonds.
To the naked eye and to anyone except a diamond expert with a powerful microscope these are already perfect diamonds and indistinguishable from flawless.
The internally flawless grade gave diamond manufacturers a choice to leave blemishes on the surface of the stone and achieve a grade higher than vvs 1.
Clarity determines how clean a diamond is.
Sadly many consumers fall into the beginner s trap of buying a vvs diamond because of misconceptions about diamond clarity.
For this reason gia and ags are highly.
Internal graining is a type of inclusion caused by irregularities during crystal growth that can appear as lines angles or curves.
The imperfections of the vvs diamonds can only be spotted by an expert s eye under a microscope.
For instance gia can grade a diamond as si2 but a different lab grade it as vs2 clarity.
If the inclusion is closer to the edge of the diamond and therefore less detectable it s considered a vvs1 stone.
The vvs clarity grade includes two subcategories.
