Here is a great deal on a slightly funky Fancy Yellow VS1 diamond.
The reason GIA gave it "Fair" symmetry has nothing to do with the outline of the stone- which is perfectly symmetrical.
The reason for the grade is because the center line is slightly off-center. This actually creates some cool, larger facets right in the center of the diamond that light up nicely, if somewhat asymmetrically.
The color is a pure Fancy Yellow - it's a very clean stone.
You save more than $800 off a comparable stone with Good or better symmetry.
