Color = I but with "brown overtone to it"

[zz00ter]

I found another diamond with a great price
1.02c - XXX - I - VVS2 - for about $4,640
HCA = 0.9 EEEV
http://www.b2cjewels.com/dd-4128104-1.02-carat-Round-diamond-I-color-VVS2-clarity.aspx

The color is graded as I but the guy at B2CJewels says that the diamond
has BROWN OVERTONE to it which brings the price down.

If the brown overtone is visible enough to bring the price down so much
why isn't the actual grading of the diamond dropped to a lower grade?

The diamond is overseas and so there are no pictures of it available right now.
but I doubt I would see color issue from a picture

Diamonds on the D-Z scale can have various colors, such as grey, brown, yellow.
I believe when it happens to be brown the price is lower.

Jonathan of GOG posted a good example pic of 3 or 4 diamonds of the same GIA color grade with very different hue.
I'll try to find it.

I can't find the thread.
It can't be more than 3 months old.
Perhaps it was deleted for some reason.

Please, can someone more skilled than I find it?

Kenny, I think I remember that thread did get deleted. Some people thought it was too close to vendor advertising.

So an I grade in color is the same whether there is a yellow or brown overtone

Should I assume that even if there is a brown overtone,
it should still be near colorless - barely visible
and the diamond therefore a really good buy?

I is I.
Is vary.
As with the body-color of all grades E through Z, some are brown, some yellow and some gray (I think there are only 3 hues, but perhaps there are 4).

Amount of color in all Is from GIA will fall within a range.
Nature does not calibrate the amount of color in every I to be in the center of the range.
Some will have more color than others.
Some will be near-H, and others will be near-J.

The width of the range for an E is very narrow.
The width of range of Is is more wide and ranges get wider as you approach Z.

Whether it is a good buy is debatable.
The market has established brown is less desirable than yellow.
So if you prefer brown to yellow you may consider it to be a good buy for you.
If another person prefers yellow to brown it may not be seen as a good buy to them.

Thanks PJ.

I'll email Jonathan and ask him for the pic.
I'm sure I'll be allowed to post it since I'm not the vendor or a shill, and it would be useful for educational purposes.
It is an amazing pic, worth a thousand words.

I don't know if Kenny meaned this video; it's Goodoldgold Youtube video; The most popular colors of diamond and how they impact value.
There's talking of body tone in same color stones...

No, I was referring to one still pic.
But the video you mentioned is even better.
Thank you for suggesting it!

BTW, Jonathan is out of the office so we'll see if GOG can find the pic.

If you don't want to watch the 12-minute video here is a screen capture from it.
Also, I wanted to post this pic for the record since the original pic has been deleted.

All four diamonds were graded by GIA or AGS.
From left to right the color grades are G M N M.

You can clearly see the body colors of three different hues, Yellow, Brown, and Gray.
Again these are diamonds graded on GIA's D-Z scale for 'white' diamonds, not on GIA's Fancy Colored Diamond scale since the color does not qualify as "Fancy" per GIA.

Key to this topic is how the hue of the body color affects price within the same color grade.
All other things being equal, yellow is most expensive and will face up whitest of the three, gray is next, and brown is the least expensive, per the GOG video linked above.
Sometimes brown can have pink undertones, a nice bonus.

Kudos to Jonathan for this lesson.

I actually think the brown undertone is cool and might it face up to look champagne-y colored?

It might not be what you're looking for but it could be a very unique stone.

 

[acebruin]

color with brown overtone J or higher will not contain the word brown in the grade... however if the color is K or lower (K-Z), the word brown will be on the GIA report... starting from faint brown to light brown... the next color after Y-Z, light brown is Fancy Light Brown...

 

[Fancygems]

In reference to the picture provided by GOG I prefer a brown hue or undertone! Which one does your eyes prefer?

 

[Tekate]

That was an very interesting video.. thank you so much for posting it.. I think the brown it would great if set in rose or yellow gold.. it's quite unique.. the GOG site has so much interesting info. .thanks.

 

[Tekate]

the brown overtone looks great.. if you are willing to set in rose or yellow gold that would be a heck of a gorgeous ring.

 

[zz00ter]

The diamonds in the video are graded as following
white = G
yellow = M
brown = N
grey = M

An I grade (being classified as near colorless) the diamond should be quite colorless and the brown should not be very visible - or am I wrong? How much difference would there be between a I yellow vs brown undertones stone?

 

[kenny]

How much difference would there be between a I yellow vs brown undertones stone?

How much?
I think the only answer to that question is a good picture of an example a very-yellow I next to a very-brown I, both up side down on a white background.

Perhaps a vendor can pull two such diamonds and post a pic.

1. Technically if a diamond is D-F (colorless), it doesn't have ANY tone.
2. Yellow tone: G-Z.
3. Brown tone: G-J, K-M faint brown, N-R very light brown, S-Z light brown. Grades of J or higher, GIA will not note the color on the report except on internal GIA docs.
4. Gray tone: G-J, faint grey, very light grey, light grey. Gray is an odd one (no K-Z letter grade on the report). Grades of J or higher, GIA will not note the color on the report except on internal GIA docs.
5. If a diamond has a color other than yellow, brown, or gray and has an equivalent color grade of G or lower, the diamond would then be graded in the fancy color grading scale starting with faint, very light, light, and then the fancy colors.
6. In summary brown tone is graded like yellow tone. Gray is an odd one, it won't receive faint gray until color K or lower. Other colors will start with faint (insert color here) starting from G or lower.

Thanks! It's really informative
