E vs F color noticable difference?

[cyberguy69]

Hi,

I am trying to decide which of these two diamonds to buy. They differ in price and color (E vs F; 10% price difference) They both have SI1 clarity rating but the F color one has some crystals on the table (from the plot of the GIA report - I found both diamonds online so I can't look at the actual stones) and the E color one has a long feather at the bottom of the stone. I wonder if the crystal will be very apparent and if the long feather will affect the durability of the stone (i.e. cause the stone to split upon impact).

The F stone is below my budget and the E stone is just over my budget. But I wouldn't mind paying more for the E stone if it is quite a bit better then the F stone or if it is better value. Can an average person easily tell the difference between the two stone or are the differences only on paper? Any help is greatly appreciated!
Thanks.

Frank

This is a great reference- http://www.goodoldgold.com/4Cs/Color/Colorless/

Less than 1% of diamonds that come from the earth are D or E, which explains the 10% price increase over your F. But I bet the responses you will get from the experts will be that no, an "average" person would not be able to tell the difference between an E and F, especially once it is mounted. Once mounted, many experts even would not be able to tell the difference. Some will go as far as to say the average person can't tell the difference between a D all the way down to perhaps the H range mounted in jewelry.

Good luck!

Have you tried running the numbers of both diamonds through the HCA?
A better cut F will look better than a not as well cut E because it will have better light return.
My cousin has a 2.26ct E and I had a .88 J. Well my stone faced up white even next to hers.

I don't think the colour at that range would be noticeable, but I would suggest the vendor give you their report. I'd question about the inclusions - if one is too close to a table, that could be more of an issue than the colour. You'd hate to get this gorgeous stone, then have it crack when accidentally bumped! (granted - that could happen to any stone, but you wouldn't want to knowingly purchase with an inclusion that could put the stone at risk)

Ask the vendor for their assessment.

I would absolutely buy an F over an E as long as it was equally well cut and eyeclean. I can't really read the angles on those reports to comment on cut, though.

Thanks for your opinion.

Here are the specs for both stones.
E color stone
table 57%,
crown angle 33%
pavilion angle 40.6%
medium to slightly thick girdle (3.5%),
crown depth 14.5%
pavilion depth 43%
total depth 60.6%

F color stone
table 57%,
crown angle 34.5%
pavilion angle 40.5%
medium girdle(3.5%),
crown depth 14.5%
pavilion depth 43%
total depth 61.1%

They are both Excellent Cut VG polish and EX symmetry

I found another diamond which is also E color but cost only $150 more.. the angles are different though it is also graded excellent by GIA. All other specs are the same. Does it matter much?
Here are its specs:
table 58%,
crown angle 34.5%
pavilion angle 41%
thin to medium girdle(3.5%),
crown depth 14.5%
pavilion depth 43.5%
total depth 61.2%

I just don't understand why this diamond is $600+ cheaper than the first E color stone. Is it because even though they are both graded "excellent" cut, the first E stone is cut a bit better than the other? Thanks for all your help!

Stone #1) 0.8 on HCA with ex/ex/ex/vg
Stone #2) 0.5 on HCA with ex/ex/ex/vg
Stone #3) HCA will not give a score due to thin girdle.
Here's a link to the HCA:

Thanks for the feedbacks.

Would the inclusion on the F diamond be visible by an untrained eye at a close distance..(i.e. 2 feet away) and would it cause durability issue? The inclusion is supposed to be crystal, not cleavage, cavity or feathers.

It's hard to validate if a diamond is eye clean - validate with seller is the only way.

I have a high E diamond that I have been told is almost D. It is really white .. haha .. maybe too white. In conclusion, I think F is great and even price aside .. I may buy F in the future.

You sure the E stone doesn't have 40.8 Pavillion instead of 40.5 u provided???

I think GIA do 0.2 degrees increment, so odd number is not possible.

that would explain the thin girdle gven by HCA too.

 

[cyberguy69]

sorry.. it is 40.8

Hi Enerchi,
Are you talking about the crystals on the F color stone? Are u suggesting that it would potentially cause the diamond to crack if hit at the right spot?
I also worry about the feather at the bottom of the E stone.. it seems quite long
