F color princess cut looks warmer than my H color rdiamond

[VCary]

I just purchase a 3/4 princess cut diamond that is F in color. When I got home I put it side by side with my 1/4 princess cut that is H in color and my F color stone looks warmer. I tested it out in every room and lighting and the F stone still look warmer. What are the possibilities?

Who graded it?

Who is the grading done by for each diamond.

1. Ditto April and Gypsy - incorrect grading
2. Dirty stone(s)
3. Heavily included stones (the smaller "whiter" H in particular, clouds/wisps/etc.)
4. You're comparing face-up rather than from the side/underside and what you're seeing is an "apparent" (vs. actual) colour difference due to differences in light return
5. Your eyes are playing tricks on you

Yes, if a reputable grading lab like GIA or AGS graded the H but your "F" was graded by one of those other labs with looser grading standards that could be one explanation.

Could also be cut - a well cut diamond looks as though it faces up whiter.

A larger diamond has more mass and depth and it concentrates color more strongly compared to a smaller one. There's some rule of thumb with rounds that it's hard to see tint in .25ct and under, or something like that.

The grading for the 3/4 was done by egl as for the 1/4 I don't remember, but it was a certified diamond as well. I did compare them from every angle especially from the side and still notice the tint. The bigger stone is a VSS2 n the smaller one is SI1. They are both clean and I can only see one inclusion in the smaller stone. I am thinking the grading is wrong as well, but was hoping there are other explanations.

Sounds like you have a case for 3 of the above mentioned things.

1. It is EGL graded. :/
2. Smaller diamonds will generally *always* face up whiter than larger diamonds. The larger the diamond the more color it absorbs. In an EGL graded one even moreso since they're generally off by 1 or more color grades.
3. Cut quality also contributes to a brighter face up appearance which translates in the eyes of most laymen to a "whiter" face up appearance.

Kind regards,
Rhino
