Diamond Query: Black Spot Under the Table - Light Leakage or Just Bad Office Lighting?

| Anonymous Reader

Hi Sebastian, I wanted your opinion on this diamond. It is a faint brown K and I love the pink, but I ultimately want something classic. Will this diamond be white face up?

1.54 CARAT K-VS2 EXCELLENT CUT ROUND DIAMOND SKU-5407841

SKU-5407841 – 1.54 CARAT K-VS2 EXCELLENT CUT ROUND DIAMOND

Would you recommend I get a yellow tone K instead if I want a classic warn tone diamond? I will have it set in a 14 karat six prong knife edge band. Thank you!

Thank you for your inquiry. I am happy to help! The diamond color grading scale is very subtle. My thought is that this diamond will appear white in the face-up position.

If, however, you put this diamond next to a D to H color diamond, for example, you will most likely see that this diamond has more warmth.

Most of its warmth, however, comes from the profile view of the diamond, which will not be easily seen once the diamond is set into the ring setting.

I will say, this diamond is an excellent choice. It has superb angles/proportions. You can purchase this diamond with confidence.

I hope this helps. Please let me know if you have additional questions!

Thanks Sebastian,

Do you think this diamond:

Will appear lighter in the face up position than:

SKU-5407841 – 1.54 CARAT K-VS2 EXCELLENT CUT ROUND DIAMOND

They are both Ks but it appears as though the brown make its darker than the yellow. I’m in a bit of a panic because I think the faint brown has been purchased for me in the last 24 hours and I could have it swapped out before it ships if I am quick to act.

Which diamond would you pick between the two or is the difference between them negligible?

Thank you!

It is my thought that the 1.50ct may appear lighter in the face up position. Both diamonds are an excellent choice, it just depends on which K color you prefer.

Personally, I would choose the 1.50ct.

Hi again Sebastian,

My hunch proved to be correct! This diamond was purchased for me:

SKU-5407841 – 1.54 CARAT K-VS2 EXCELLENT CUT ROUND DIAMOND

The only downside is that in my office lighting it looks awful and has a black spot under the table. At home, outside, in the car it’s beautiful. Am I crazy? Or can a diamond with these proportions have light leakage? Please help! Thank you!

Your Diamond Teacher |

Hello! Are you suggesting that the black spot under the table is light leakage?

Yes. But I suppose that isn’t logical because if it where light leakage it would do so in every light? Perhaps my 40.6 pavilion is a 40.55?

This seems like a similar problem. I only have till the 23 to return if need be. Thanks for your help!

Your Diamond Teacher |

Putting the numbers aside, you need to be happy with what you are seeing in the actual diamond. If you do not like what you are seeing in the diamond, then you should return/exchange it.

Thanks! My fear was that all diamonds would do it in this light. I’m lucky that a coworker is also recently engaged and her 0.9 carat E did the same Ink blot effect. Sadly, where I am seated has the worst of it. I’m keeping the diamond and getting a lamp!

Thanks for all your assistance. I just really wanted to be sure it wasn’t the slightly thick girdle.

Your Diamond Teacher |

LOL. Yes! Get a lamp! The girdle wouldn't have anything to do with it. 🙂

I had James Allen send my the ideal scope image and from my novice interpretation, I say its Very Good or Excellent. Where would you place it Sebastian? Thanks!
