How Well Do You See And Diamond Color Differences?

Let’s do something fun in today’s blog post.

I often get asked questions like “Do you think a H color in a diamond is good enough?” , “What is the general consensus on buying diamonds in the colorless range?”, “Does the general public perceive color or hues in diamonds easily”?

Multi-Colored Flashes of Light Within Diamond

It all boils down to one thing: How well do you see colors? In diamond grading, the differences between 1 grade is usually minute and it takes a trained eye to immediately discern between 2 diamonds. For example, if we compare 2 well cut diamonds of G and H side by side with similar carat sizes, I can tell you that 90% of the people can’t tell a difference in the face up view. 

Ultimately, the choice of color should be up to your individual tastes as you will be the one wearing the piece of jewelry. And can you really perceive the nuances of color changes?

Here’s a fun and simple 5 minutes test that you can do.

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

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

Yep, I personally have a color sensitive eye and this is one of the tests that I can do with ease. If you had done the tests too, feel free to leave a comment below with your score. I would really love to see how our readers fare.

Let’s Get Back to the Topic on Diamonds…

The truth is, even with a trained eye, I can’t tell the differences between a mounted D colored and a F colored diamond immediately. Until I can scrutinize a little closer and inspect the stones under the correct lighting conditions, these minute differences won’t be obvious.

You see, this is what really happens in the practical world. Most people on the streets probably glance at your jewelry and most can’t tell the differences between 1 or 2 color grades. You don’t have fret too much or get too obsessed in buying diamonds with the best specifications. Sometimes, the premium paid might not necessary translate into something that people can 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?

I would love to hear your opinions and how you would place your priorities on these factors. Do drop a comment and let me know! has an enormous inventory of GIA graded diamonds with interactive videos to help shoppers pick the perfect diamond. Highly recommended!

    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. 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 for dropping by and leaving a comment. The 4Cs are really subjective to individuals and even the experts have place different priorities to their needs too! You might find this an interesting read:

    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 .

    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

    Well done! That’s probably means you have to pay more for higher colored diamonds if you are color adverse.

    Hi Paul: I would prefer a lower colored diamond with an excellent cut and VS1 or better clarity.

    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!).

    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!

    Scored 0 after two previous attempts (18, 19). I find calm and relaxedness necessary.

    I scored a 0 and I can definitely distinguish between colorless and near colorless diamonds. Will be opting for colorless when it comes time.

    I scored 0 first time. Does this mean I will more easily distinguish colourless from near colourless?

    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.

    I got a perfect 0 on my first try, but I’ve been a professional photographer for a couple of decades. Thanks for all the great information! I am trying to replace a men”s vintage ring that was stolen from my husband. It was his late Daddy’s. Not having a whole lot of luck so far.
    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.

    Male – 63 yrs old – Scored a 0 on first attempt, but there’s not much difference between side by side hues. Would be difficult to discern if only two blocks.

    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

    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.

    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!
