How Well Can You See Diamond Color Differences?

Diamond with multi-colored dispersion and reflections of surroundings.

When it comes to diamond color, first time shoppers often have questions along the lines of: “Do you think a H color for a diamond ring is good enough?”, “What’s the best color grade to buy if I don’t want to see any yellow tints in the diamond?” and “Does the general public perceive color hues in engagement rings easily?”

Well, it all boils down to one thing: How well do you personally see colors?

In diamond grading, the differences between 1 color grade is very minute and it takes a trained eye to discern between 2 loose diamonds under a specific set of lab conditions.

In reality, when diamonds are mounted in a setting, it is going to be very hard to detect color differences in casual viewing. For example, if we to compare 2 diamond engagement rings with G and H color ratings side by side, I can tell you that 99% of people won’t be able to tell any differences at all. 

But what if you belong to the 1% of people who have extremely sensitive eyes? Would you be able to see visual differences between color grades in real life?

That’s what we are going to do today.

To find out how sharp your eyes are in discerning color nuances, here’s a simple 5 minutes test for you to quickly find out:

I Did The Test Myself And Here’s a Screenshot of My Score

online color vision test

Here’s my first attempt and I scored a perfect score of 0.

Having been around diamonds, I developed a very sensitive eye and this online color challenge is a test that I can complete with ease.

If you had completed the color test as well, feel free to leave a comment below to let us know what you scored. I love to hear from readers and see how you fared.

And on this note, I want you to know that it is completely normal if you didn’t get a perfect score.

It doesn’t mean there’s anything wrong with your eyes. In fact, I see it as a blessing in disguise as you can save money on your diamond ring purchase with a lower color diamond.

Also, I want to highlight one mistake that consumers make by having the misconception that a higher color rating automatically equates to a diamond with better sparkle and brilliance. Cut is actually what determines the performance of a diamond and not color.

White Flash and James Allen are 2 highly recommended vendors when it comes to ideally cut diamonds. Besides a good selection of diamonds, they also have hundreds of beautiful ring designs to choose from.

Comparing Various Color Grades in Real Life For Differences

Here’s the thing, even with a trained eye, I am not able to tell the differences between a mounted D color and an F color diamond easily. Until I can scrutinize and inspect the stones closely under correct lighting conditions, any color differences won’t be obvious.

And this is what really happens in the practical world.

Most people on the streets probably glance at your jewelry for a couple of seconds. If a trained professional can’t see differences immediately, do you think it is likely for the public to tell the differences between a couple of color grades?

I’ve made a video comparison of colorless diamonds vs near colorless diamonds to help you put things into perspective. This suite of 5 engagement rings consist of diamonds with the following color ratings: D, E, F, H and I.

Watch the video and see if you can detect the yellow tints in the near colorless diamonds.



The bottomline is, you don’t have fret too much or get too obsessed in buying diamonds with the best color specifications. Sometimes, the premium paid might not necessary translate into something that you can visually appreciate.

Here’s more food for thought… Would you get a bigger carat diamond at the expense of lower color? Or, would you rather get a diamond with higher clarity and sacrifice color?

Ultimately, the choice of color would be up to individual tastes as you will be the one wearing the piece of jewelry. I would love to hear your opinions and how you would place your priorities on these factors.

    I scored 48 in the test. A little disappointing but I guess I can’t differentiate color that easily.

    This test isn’t 100% accurate but rather, serves as a useful gauge. Even if you scored a perfect 0, it doesn’t mean that you will automatically be able to see color nuances in real life.

    If you look at it from the positive side of things, you have higher tolerances to color and can probably go down to lower grades without noticing much differences in a diamond’s outlook.

    thanks Paul. for the most useful information. This is helping me gain more insight to diamonds and how to choose a special diamond. I scored 35 , not giving much attention to the colour grading since the tints are not noticeable to me.

    In a way that’s good since you can buy near colorless diamonds and not see a tinge of color in them. Too many consumers get worried about seeing color when it really isn’t that straightforward to do so in reality and this is a test that helps you gauge your eye sensitivity.

    I scored an 11. I think that means that color is important. Jewelers have pulled out diamonds for me and I always say it look too yellow. This is helping me to choose a diamond

    Hi Paul – an enjoyable test. I’ve always thought I have quite good colour sensitivity (a critical eye some might say!) but only scored 7 in the test. However, at almost 65 years and with no prior experience in diamond grading as such, I guess that’s not so bad. Colour and clarity would be important to me, but also the cut, and not so much the carat. (Though my wife may have something to say about that!).

  12. JK-
    December 2, 2015 at 4:56 am

    Scored a 3 :-) Would like to try again in better lighting without sunlight blinding me.

    Lowest colour I can settle for is E. The yellow in G onwards is glaringly obvious even when mounted. VS1 to be relatively eye clean. Carat is least important of the 3 mentioned. I really can’t understand ppl buying SI stones just to get more carats. Quality over quantity!

    If you get to compare diamonds in a proper environment and lighting, I think you would be able to see very subtle differences in between colorless and near colorless diamonds.

    Hi Paul… An enjoyable test especially since my fiance and I went ahead and purchased a 2.3 CT emerald cut. H Colour VVS1.. I scored 12 ! I learnt a lot from your 4Cs and what ultimately becomes a personal choice of either going for better colour or larger carat. I found that because I am enamored with the clean lines and simplicity of the emerald cut that I could not forsake clarity. Eye clean would be important. Being Tall I also wanted at least 2 carats and now that i have received the ring, the H colour does come off as White! I want to thank you for the online retail sites that you proposed as they made the buying process more scientific and I could view the stone up close. There was also an expert to help me identify where the inclusions were and whether it would be noticeable as it was VVS1, it was certainly eye-clean!! I decided against an IF H Colour which was several thousands more expensive as the VVS1 clarity was great!! My fiance is of course all the more happier!! Lol..
    I am learning more and more from you Paul so thanks again in giving me the needed assurance to dive into a large purchase.

    Thanks again.

    I scored a 0! I would much prefer clarity, and excellent cut of the diamond than size. I have learned a great deal from your newsletters mainly about cut, girdle, etc… I would really like to find a perfect diamond. I know it will probably be small due to my budget and the increased price of a perfect diamond but it is a dream of mine to own a perfect diamond. Thank you for your newsletters and wonderful information.

    Thanks Paul, this was interesting, I scored a 0.
    I work in a jewellery store and always wondered if my customers were seeing as much color differentiation as I was. It gave me better perspective when dealing with color in our diamonds.

    Hi Paul, I got a 2 on the test..
    It would depend on the type of ring I purchase.. for an eternity band, I go for f/g color sl1 clarity and get a very good cut…40 each diamonds, if it was one diamond ring, I would go for g/h color go up a step in clarity very good cut and try for a full carat size diamond..
    Thank you for your advice Lynn

  27. Paul Gian-
    January 13, 2018 at 10:42 am

    Personally, very good cut is not going to be good enough. There’s already so much junk in the excellent cut grades that I will never consider bottom fishing in the Very Good cut range.

  28. Marnie-
    May 11, 2018 at 1:36 pm

    I scored a 0. I am definitely drawn to color and cut and will choose an eye clean diamond of VS1 or VS2 with a color rating of H or better. Currently shopping in the 1.5 -1.75 range. Your articles have been very helpful and informative. Thanks Paul!

    Only time I think a Zero on a test is perfect! As a painter, even minute changes in lighting and angle can influence one’s interpretation of color. I know I drove a jeweler friend nuts when looking at the subtle differences between each of the color grades. Buy the best cut and clarity, that you can afford. The carat weight & color is absolutely a personal choice. Color wise, once you are at an “I” or above, unless you have multiple diamonds side by side in a setting, your diamond will be lovely.

  30. Paul Gian-
    October 1, 2018 at 2:13 am

    You nailed it. The lighting environment actually affects the color of stuff we see. Some jewelers use yellowish spotlights (e.g. Tiffany) and it makes even the whitest diamond look yellowish. I would say most people would be ok to go down in clarity to VS2 or SI1. It’s an attribute people can save money on as most inclusions can’t be seen with the naked eye at those ranges.

    December 10, 2018 at 6:37 pm

    I scored 0 on my first attempt. However, while I must have put all the hues in the correct order, I thought the hues in the top row still seemed uneven so that it seemed as though they contained hues that did not belong in the sequence. It is like when one looks at a watch bezel of rainbow gems and thinks that there should have been a more gradual change of colour. I thought the sorting of the hues at the left or teal end in the third row involved the most subtlety and do not think it would make a huge difference to the unity if these different hues were side-by-side in the same piece..

    I scored a 0! Also very glad to have come across your site, I purchased two Moissanites as of late, and boss was not pleased. Your article has helped me see the differences. Quick question…the doubling effect, is it prevalent in all shapes?

  33. Paul Gian-
    January 25, 2019 at 3:43 am

    Yes. The doubling effect is an intrinsic property of Moisannite. You will see it in every polished stone regardless of shape.

  34. Debbie DeRosa-
    April 8, 2019 at 5:13 pm

    I scored a 0. I watched your video about comparing E,E,F,H and I diamonds. In almost all of the conditions, I couldn’t tell the difference in the colors. In the ones where I felt I could see a slight difference, I actually preferred the I to the D! Imagine that! Thanks for the information. Very helpful!

  35. Paul Gian-
    April 8, 2019 at 5:21 pm

    The color test is actually the more accurate test for color sensitiveness in theory. The Youtube videos reflect what you see in reality. In my youtube videos, the diamonds cut quality and performance actually affect the “whiteness” of the stone depending on the environment they are in.

  36. Keliann-
    October 13, 2019 at 3:34 am

    I scored a 0 3x and would give anything if you’d do that same video with Emerald Cuts. I know Emerald cuts show differently and would love to see this comparison so I could know if I’d be able to settle for a smaller mostly perfect or larger less perfect.

  37. Paul Gian-
    October 13, 2019 at 8:37 am

    Emerald cut diamonds tend to absorb a little more color because of their cutting style. I will put that on my to-do list for a line up of 5 emerald cut diamonds with different color grades and similar carat sizes.

  38. Keliann-
    October 13, 2019 at 3:55 pm

    Paul, that would be so very helpful to see Emerald cuts in your line up, Thank you. I’ve been reading al learning for weeks now but will hold off purchasing until I can get a better understanding of Light then be able to see if I can go down in my color choice of D if I won’t notice it. You are wonderful in helping us for this.

  39. Paul Gian-
    October 14, 2019 at 3:28 am

    Just to be clear, this video will probably not take place until next year as I am already in the midst of writing up and recording other videos. Those would be keeping me busy for a while. I would say that most people would not be able to detect color in an emerald cut diamond with F or better color. It’s unnecessary to buy a D just for it to be eyeclean. Anyway, if you were to buy from a reputable vendor like JA, you will have the opportunity to inspect the diamond for 30 days. If you think you can see color in person, just send the stone back for a full refund and choose another. It’s a little of a hassle but JA is great that way.

    I scored 0. Female, pushing 60.
    But I’ve always known I was quite sensitive to diamond colour since inheriting a family ring years back where I could see a lot of yellowness, but others couldn’t.
    I’ve just purchased an E diamond as I prefer the lighter shades, and being set in platinum.

  42. Tin-
    August 20, 2021 at 7:42 am

    I scored 0 (F, 30-39). I usually scored good with color test so I’m a bit worried to get diamond color grade M . Currently trying to choose between F, H, K or M. All are round, 3EX and below 0.5 carat (my criteria). I prefer yellow gold as best metal color for my skin but I also want to do halo design. Still confused what to get. FYI, this is not my engagement/wedding ring but as addition to jewelry collection.
