I had a beautiful diamond that believe it or not got a chip in it!

It was 2 carat, all very good ratings, VS1 and H color. GIA certified.

The replacement service we are using through our insurance company said the chip happened because the girdle had a very thin side.

So we are getting a replacement. The problem is we haven''t had an upgrade on our appraisal in five years so the amount of insurance on the ring is only $19K.

The replacement service has found a ring - in INDIA. They have said that they do not have the right to return it unless the ring comes in and is not the diamond in the new GIA certificate they are showing us.

So here are the specs - it looks great to us but we are a little nervous to approve w/o seeing it! Are we missing something?

Shape- round brialliant
Measurement - 8.27x8.31X5.09
Carat weight 2.13
Color H
Clarity VS1
Cut grade - excellent
Finish - polish and Symmetry - both excellent
Flourescence - None
Surface graining not shown.

Thank you for your help!!

Do you know anything about the cut of the diamond? Or the GIA report number so we can look it up? We need depth, table, crown and pavilion angles or the cert # to be able to tell you if it''s a nice stone or not.

What are the crown and pavilion angles?

Welcome hol pol,

As Neat says we need the information above, the crown and pavilion angles in order to be able to judge this diamond for cut, can you obtain and post them please?

 

[hol pol]

GIA registry number is 1106183554

Girdle is medium and faceted.

I think depth is 61.4 percent?

But I''m not sure the rest.

Does that help?

61.4% depth, 58% table, 34.5° crown angle, 41.2° pavilion angle, HCA 3.4

The pavilion angle is a little bigger than what most of us here would like, might result in some light leakage and a less brilliant stone. Can they give you an idealscope or ASET image of the stone?

 

[hol pol]

I can ask - not sure. So that could impact the look of the diamond?

Possibly but the pavilion angle isn't horribly steep in my opinion, plus the cut advisor penalizes diamonds with a steeper pavilion angle - no real way to tell without an Idealscope image as we can only speculate on what the diamond could do. I would not want to take a diamond without a return policy personally anyway, is this a condition of replacement? Is there a way that you can find some others?

Is likely to have a bit of table leakage.
Biggest problem is you were under insured.
It might be better than what you had.
What are the numbers on your original diamond?

To get something much better you would have to cash out and add some cash to it.

And that is a good point, do you have the info on your original stone?

I will look tonight and see what I can find on my old diamond. Thanks for your help!

Storm, Lorelei, given that her appraisal was five years ago, I do not think the report will have the crown and pavilion angles we need for comparison with the present replacement stone, right?

No but I can get a general idea without it maybe.
There are some table/depth combos that are not that great no matter what is in them.

Here are the old specs -

Report Type: GIA Diamond Grading Report

Round Brilliant

Measurements: 8.16 - 8.21 x 4.93 mm

Carat Weight: 2.00

Color Grade: H

Clarity Grade: VS1

Proportions:

Depth: 60.2 %

Table: 58 %

Girdle: Very Thin to Slightly Thick, Faceted

Culet: None

Finish:

Polish: Very Good

Symmetry: Very Good

Fluorescence: None

 

[stone-cold11]

True.

 

[hol pol]

And yes - it does not have all the specs as you see.

So I''m confused. When I look online and talk to the replacement service I am using I read/hear that pavilion angle of 41.2 is within the ideal range? Also, the cute grade is EXCELLENT so doesn''t that mean all the proportions add up to a very good diamond? How could it get and excellent rating if it had this table leakage you talk about ?

 

[strmrdr]

old specs arent enough to compare unfortunately.
Could have been a good one.

GIA EX extends into the steep/deep range with some table leakage.
Some table leakage might not be that visible but a lot is visible.

 

[hol pol]

So this table leakage will be obvious to the naked eye and make the diamond not look good? I"m still totally confused as to how you can get and excellent cut rating if there is "table leakage"?

Ditto

Hol Pol, GIA Ex cut grade is broad and can give this grade to diamonds which have steep deep angles as Storm explained, so it is best to evaluate each GIA Ex on its own proportions rather than assume the Ex cut grade is going to get you a good looking stone.

Apparently, GIA did a ''test'' under questionable and debatable set of conditions, lighting conditions, viewing angles, etc., with a large sample size of non-pros and used that to quantify their cut ratings and this is the results.

 

[hol pol]

thank you everyone for your help. Now this still could be a really great diamond correct?

 

[stone-cold11]

It could still look great. As the HCA states, worth buying if the price is right.

It could look good, the HCA penalizes diamonds with a steep pavilion angle, and the angle could be a lot worse than it is. As Storm says, if there is any leakage then it may not be that visible, but really all we can do is speculate as we don''t have images of the diamond.
