Fancy cuts show more color than rounds. Hands down. A G color round will look whiter than an oval. Cut is king, then clarity. My stone is an I color Vs1 oval with a fantastic cut and it is so glowy and sparkles! But she does look warm. Mine is set with G color melee stones and there is a noticeabl difference.


larger stones do show more color. It really depends on how color sensitive you are. I love the look of lower color diamonds and prefer them.

bluesybee:  G is a pretty good grade of colour to start with but it does depend on how colour sensitive you are. Some will see colour in that grade and some see no colour in a lower grade like an I or a J, it depends on the individual stone and the person.

The larger the diamond the more colour it will show. Fancy cuts and certain cuts show more colour than other cuts. The cut grade can also be a factor because say a J colour has an ideal cut it can appear much whiter than another stone that is the same colour grade but has just a ‘good’ cut. Cut is king like the PP has said, cut can affect the colour, clarity and how much your diamond will sparkle. I’d personally rather have a smaller stone with amazing fire than a larger diamond that lacks sparkle or looks milky/cloudy. If it has bad clarity it can also make the colour look bad too. 

No, I don’t think Blue Nile is lying. Some places dont bother to send they’re diamonds out to get tested because of they’re size. Have you tried James Allen? They show 360 images of each diamond and you would be able to see what your getting.

Fancy shapes tend to reveal tint a lot more than rounds do — especially cuts like pear and marquise and princess where color concentrates at the tips/corners. I would be very comfortable setting an I round in white metal, but not an I pear. And yes, a beautifully cut stone will usually look whiter than a poorly cut stone.

A G diamond is always going to look near colorless, no matter the cut. If you put a fancy shape next to an ideal cut round brilliant, you might be able to notice the difference in color if you are color sensitive, but it’s doubtful. Diamonds are graded upside down, not face up, so a GIA G oval and a GIA G round brilliant are going to basically look the same.

You may notice more difference in the lower colors, like J and below, but a G will always look very white.

The larger the stone, the more evident the color. Fancy cuts tend to show more color than RBs. But at the size you’re looking at, anything up to I color will look white. Diamonds under .3 cts are often not certified. It costs money to do so, and the return on investment is not large enough to make it worthwhile for many places.

bluesybee:  2 tips. The pricescope forum will be immensely helpful in your stone picking. And if you see a stone you like online, and it’s GIA certified. Get the cert number and google it. You’ll then be able to compare the prices for all the online retailers offering it (there’s one big inventory they all dip into as well as keeping their own stock of diamonds). There can be up to 30% price difference on the same stone.

Fancy shaped diamonds (any cut other than round) will show more body color. So if your wanting a fancy shaped diamond to he very white with no warmth, then I suggest going with G color and up and staying below 1 carat. For larger fancy shapes a higher color grade may be the best way to go for a icey white stone. With round brilliants, as long as they are very good – ideal/excellent cut with either GIA or AGS certification, an I and sometimes J color can be very white. You will see no warmth what so ever with H colors and up. It’s true the smaller the diamond the less color it will show, however I don’t think there would be a significant color difference between the two round diamonds. I have a 1.51 carat G color round brilliant diamond that shows zero warmth. Just make sure it’s got a great cut and you should be just fine!
