Venus Grading System (VGS®)

Sub-dividing Color grades
Share  
As the color scale progresses from D to Z, the range between consecutive color grades becomes wider.
To report these color range accurately, VGS assigns ‘Better’ (+), ‘Standard’ (), and ‘Weaker’ (−) sub grades to each color grade. This expands the standard 17 color grades into 34 color grades, offering greater precision.
