VVS1 and VVS2 (very, very slightly included)
Very, very slightly included: inclusions so slight they are difficult for a skilled grader to see under 10x magnification.
How to read it
VVS1 and VVS2 are the third and fourth of the 11 grades on the GIA clarity scale, below FL and IF. GIA explains where the letters come from: the terms were once very very slightly imperfect, very slightly imperfect, slightly imperfect and imperfect, later shortened to VVS, VS, SI and I.
Also searched as: VVS, VVS1, VVS2, VVS clarity.
Grades describe a stone as a grading laboratory saw it. This page explains the grading scales; it doesn’t grade or value any stone.
VVS1 or VVS2?
Both sit in the same category; the 1 marks the better of the two grades within it.
On other laboratories’ reports
HRD Antwerp’s scale uses the same codes, VVS1 and VVS2, and calls the grade “very very small inclusions”. The US Federal Trade Commission’s jewelry guides say that when a seller states a grade, the grading system it comes from should be disclosed.
