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.
 
It depends who is looking. I have a hard time distinguishing between D-F when stones are next to each other. I might be able to tell D vs G, but I know the difference would not be bothersome to me, so I wouldnt want to pay for D color. But others feel differently.
 
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.
 
With an Emerald, a super colour sensitive person might be able to see the difference between D and F, but thankfully I'm not one of them! You should be able to notice the difference between a D and G though. There's a noticeable warmth, especially with step-cuts.

Keep in mind that this is the case with stones larger than a carat. If you asked someone to work out the colour grade of a .2ct emerald at it's actual size, it would be impossible, especially once set.

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.
 
It depends on one's sensitivity to colours.

My G/H diamonds are very white on their own when set against white metal.

However, I can see a tint in them when they are pitched next to my E colour 1.19ct EC diamond.

My mind-clean colour is G/H; however, I can go lower for a small (about 1ct) wonky OEC that I would like to get, Gypsy set in Platinum, to wear as a right hand ring.

DK :))

Side Note: @nojs someone should do a IGI to GIA color comparison thread!

It seems like it’s so stone dependent! I ordered a GIA I lab stone and it had a definite tint. So returned for IGI H that seems to have much less tint to my eye. I never had them at the same time but here’s a screenshot of the video from the jeweler. The top stone is the GIA91C2BC48-C98C-4534-941D-22EBF7DF6024.png
 
Do you know your personal color tolerance? That's where I would start. Also, the lower down the color scale you go, the wider the range is, so for example you can have a high G or low G. The size of the diamond matters as well, generally the bigger the diamond the more color concentration. I'm super color sensitive, but still ended up with a Distinctive Gem Emerald cut that is a G. It was custom cut, and I absolutely panicked when it came back a G, but I decided to see it in person before making a decision. I saw a tiny bit of color upside down when it was unset, but it was very white face up and was cut beautifully, so I kept it.
 
@EClove and @Diamond Girl 21 both give good examples. GIA grades from the bottom. I think face ups can definitely differ even within one color grade due to factors like cut and depth.
 
Found this YouTube video that shows colour differences

Wow, it sure looks like that. But if I buy an F, I don’t expect to see obvious yellow.

Thats so disappointing and I would not be happy with that! My lab GCAL 8X F color is completely colorless with zero tint. GCAL even guarantees its 8X color grading with a money-back policy if its grading comes back inaccurate. 3ED26556-9E48-4B21-BD81-BE96D2B9E86D.jpeg

It really depends how color sensitive you are. I'm extremely color sensitive and I don't generally go lower than F, but I much prefer D & E. The only color to me that actually looks colorless is in fact D, regardless of the shape of the diamond. It's going to come down to your personal preference and how you perceive yellow in a diamond. If you are worried about seeing yellow and think you are color sensitive I would go with D or E to be safe.
 
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.

Honestly it’s going to depend on the stone. I have a GIA F asscher that looks more tinted than a GIA G emerald. But the asscher is over 2 carats and the emerald is a half carat.

Sounds like your username suits you perfectly! I would love to see your collection x

How big is the diamond? If smaller, then I don’t think it is highly visible. In larger stones, the tint is more obvious.
