I am not knowledgeable about lab diamonds, but I do have an GIA F color earth mined stone. There is no hint of yellow in this stone.
Here it is set in platinum. The traps next to it were graded E/F (not certed).

In modern stones F/ VS2 is my fave combo.
I just bought an IGI F lab stone and I definitely see some yellow. More like a low GIA G or even solid H. I have natural diamonds in colors E, G, H, J and K, so I have something to compare to.
Just wanted to point out that an IGI F might still have yellow tint.
Side Note: @nojs someone should do a IGI to GIA color comparison thread!
Wow, it sure looks like that. But if I buy an F, I don’t expect to see obvious yellow.
I am very color sensitive.
I can see warmth in my G color 4.75ctw MRB earrings from whiteflash, enough so that I wouldn't want that color as a ring although I'm ok with them as earrings. My F/G color 10ctw MRB tennis bracelet from whiteflash seems to have less visible warmth to my eyes.
I can see absolutely no tint at all in my G color 10.22 ct emerald cut lab diamond from Distinctive Gems.
I can see a LOT of warmth in my J color 2ctw MRB lab diamond studs from lightbox.
I have quite a few D color & E color lab diamonds, and I honestly think my favorite is E color. I love bright, white stones with no touch of warmth. D looks the same as E to me, but just costs more.
I have actually come to the conclusion that I love my E / VS1 6ctw lab diamond studs a lot more than my 4.75ctw G / VS2 studs from WF. They were half the price, sparkle just as much (to my eyes), and are bigger, brighter, and whiter.
I think going below D, E, & F for lab diamonds can be tricky especially if you are shopping online. Lab diamonds below F color can often have weird tints and hues - blues, browns, greys, etc that are undesirable and often aren't represented on their certificates. I see this a lot while looking through brilliant earth's inventory. HPHT diamonds of H color & below very frequently have blue or grey tints, and CVD diamonds of H color & below can have weird brown tints.
To the naked eye on an emerald shape diamond, is there a huge & noticeable difference between a D, E, F & G?
I can't seem to find good comparisons at local jewelers.
It would be mounted on white gold, so no yellow interference.
