Need some insight on 2 stones

[kcar1981]

I believe I have my seach narrowed down to two stones but would like some insight other then the jewelers. Based on the below information which one looks better. There is a $400 difference between the two stones, the bottom being more expensive. Also, what would a reasonable price be for either stone.

Both stones are Round.


GIA 1.19 F SI2 Excellent Cut
Polish and Symmentry VG
Flourescence None
Measurement - 6.67 - 6.80 - 4.18
Table - 57
Depth - 61.5
Crown - 36
Pavilion - 40.8
Medium Girdle


GIA 1.24 G SI2 Excellent Cut
Polish and Symmentry Excellent
Flourescence None
Measurement - 6.98 - 7.00 - 4.21
Table - 58
Depth - 60.2
Crown - 32.5
Pavilion - 41.2
Thin to Medium Girdle

based on the numbers, the second G stone is the better one. you can check the prices of comparable stones under the "Prices" tab.

Ditto Julie. The star and lower girdle facet percentages would also be helpful plus do you know if this SI2 graded diamond is eyeclean to your standards? What is / are the grade setting inclusions for this diamond as marked on the clarity plot ( feathers, clouds etc?)

 

[kcar1981]

The F Color stone has a small carbon mark near the girdle and a feather on the opposite side. It is eye clean to me. Do not have any other measurements at this time.

The G Color stone has a bunch of 5 cloads and 3 crystals from the middle of the stone to almost the edges. I have not seen this diamond in person yet but a jewler I have been working with says it is eye clean and should have been graded a SI1 if that means anything. Also, if I am reading the GIA report correctly the diamond is 60% stars and 75% lower girdle facets.

cut for the G stone is better.

Make sure the clouds aren''t impacting brilliance especially as this diamond is of SI2 grade, you might want to get an independant appraiser to check it out for this before making the sale final. The measurements for the G colour look fine also, thank you!

Thanks for the help. I had the local guy return the F color and he came back today with this,

GIA 1.11 G SI1 Excellent Cut
Polish Excellent
Symmentry VG
Flourescence None
Measurement - 6.60 - 6.63 - 4.13
Table - 57
Depth - 62.3
Crown - 35
Pavilion - 41
Medium Girdle
$5700

Ran it through the Holloway Cut Adviser which came back with a score of 2.4 and all four factors graded - Very Good.

In every day life, what is the differece between a score of 1.8 and 2.4?

The 1.8 score comes from the 1.24ct mentioned before with Light Return and Scintillation - Very Good and Fire and Spread - Excellent.

The answer is maybe a lot, maybe none. Best to compare two in person.

This one is a borderline steep deep with those angles, if you can see it in person check it out very carefully to see if there are any dark dead patches on the surface of the stone or a dark ring around the table. It could be fine or it might show leakage depending on GIA angle rounding. You could purchase an Idealscope relatively inexpensively to check the diamond out, they are simple to use and the image also simple to interpret.

Read more on Idealscope here.

As to any visible difference between HCA scores, as Julie says its hard to tell.

 

[kcar1981]

Thanks again for the help. I wish I could compare them side by side but they are from two different jewelers. Do most jewelers have an ideal scope on in store? Only one place I went to offered it up since they sell heartstar diamonds. I would rather ask to use one they have on hand then buy one.

Most do not have idealscope, you can ask, no harm asking.

May I ask why? To me, for a mere pittance on a multi thousand dollar purchase, I would think it a wise investment.

Why is because as of yet my girlfriend doesn''t know I have been looking at diamonds and I would like to keep it that way. We have talked about getting married plenty but I want to make it a suprise. If I have a package deliveried to the house she will start asking questions. I guess I could have it delivered to work but then questions will come from that too.

 

[stone-cold11]

Just have the package sent to the distribution center for pick up.

That, or maybe to your parents if they''re close?

Found the plot plan for the 1.24ct diamond I have yet to see. Wanted to ask if there should be something to worry about with the clouds and crystals from the picture?

 

[stone-cold11]

Maybe, maybe not. Ask the gemologist there if it will be a problem or take it to an independent appraiser for a second opinion?

As these are SI2 grade setting clouds definitely ask for JA''s gemologist to check these out to make sure they aren''t impacting brilliance, if not you should be fine.

Huh? I don't think OP is buying the stone from JA or did he say it somewhere else?

Oh dearie me, must have misread! Whoever is selling the diamond with the clouds noted above the same advice applies, check with an appraiser preferably to make sure these clouds are not impacting performance.

Well I took a look at the 1.11 and didn''t like it. Not sure if it was the G color (I prefer colorless) or becuase it looked dark or a combimation of the both. In any case I told the jeweler to return it and he came back today with the following,

Round 1.06ct SI1
Excellent - Cut, Polish, and Symmetry
Measurements - 6.54 - 6.59 - 4.01
Table - 58
Depth - 60.8
Crown - 35
Pavilion - 40.8
Medium Girdle
$5800

Halloway Cut Adviser score of .9 (Excellent within TIC range) - Excellent Light Return, Fire, and Scintillation and Very Good Spread.

How does this stack up to the 1.24ct that was discussed earlier in my post other than size?

 

[stone-cold11]

Numbers look good. I would prefer this to the 1.24c.

Looks promising, with this angle combo check carefully for any leakage, if you don''t have access to an Idealscope inspect the diamond carefully, look out for a dark ring around the table or any dark dull patches on the surface of the stone, preferably view the diamond for this in plain daylight rather than in bright jewellery store lighting. This angle combo depending on the actual proportions ( GIA round the numbers) can sometimes show leakage, not in all cases but some so best to check for this.

 

[kcar1981]

Still waiting for the 1.06ct to be deliveried to my local jeweler for a viewing and another jeweler I have been in contact with sent me a cert for something they just recieved in a shipment.

Round GIA 1.03ct E SI1
6.54 - 6.63 - 3.91
Cut, Polish, and Symmetry VG
Flourescence - Faint
Table - 58
Depth - 59.4
Crown - 32.5
Pavilion - 40.6
Girdle - medium to slightly thick

HCA - 1 Excellent within TIC range (yet doesn't fall into the GIA or AGS lines)
Light Return - VG
Fire, Scintillation, and Spread Excellent

Should I consider looking at a stone with a very good cut or stick with excellent cuts only? Since these stones are at different stores I really can't compare them side by side. Also, should it be of concern that the 1.03ct has a cert with a April 2008 date?

This diamond proportions which are on the shallower side and could have obstruction issues. This is where the diamond visibly darkens at close scrutiny due to the viewer's head/ body blocking the light to the stone, sometimes the case with these types of diamonds. If you see this diamond in person, check it by bending over it to see if the diamond goes dark, if so this is obstruction in action - also see the video on this page titled Head Obstruction by Garry Holloway. If you can get an Idealscope to use on this diamond that would also be very helpful, here is a shallow image showing obstruction onthis page, look at the shallow and very shallow IS images. These types of diamonds often work better in pendants or earrings rather than rings as obstruction isn't an issue when worn on the neck or ears.

 

[stone-cold11]

Yap, could have obstruction issue.

You can stick with VG cuts if you don''t mind shifting a lot more stones to find the one.

 

[kcar1981]

Well the jeweler just told me the 1.06ct was sold by his vendor before it was shipped out but he sent the following stone in it''s place,

Round GIA 1.05ct F SI1
Cut, Polish, and Symmetry Excellent
Flourescence - None
Table - 57
Depth - 51
Crown - 34.5
Pavilion - 41
Girdle - medium to slightly thick

HCA - 1.8 - Excellent within TIC range
Light Return - Excellent
Fire, Scintillation, and Spread - Very Good

Any insight would be helpful. Also after the advice from before I have passed on the 1.03ct.
