Yet another "how''s this rock look?"

[tankertoad]

Larger stones of any quality are tough to find at B&Ms but I finally spoke with a local jeweler who has the following stone:

EGL Cert
1.73
J
VS1
7.61*7.57*4.73
Table - 60
Depth - 62.3
Crown - 13.8%
Pavillion - 43.6%
Polish/Symmetry - Either vg/ex or ex/vg (I forgot which was which)
Girdle - thin to slightly thick faceted

The pre report he had from the lab had 34.8/41.2 degrees for the crown/pavilion angles but I'm not sure these correspond with the percentages above. If anyone knows the math necessary to check, I'd appreciate it.

He quoted me $14.5 which, once tax is added, is competitive with internet dealers (or maybe a little better depending on this cut.

The jeweler said the stone was very nice and had lots of pop in the back room away from the halogens. The GIA cut analyzer says "Very Good" but HCA is 3.5 with vg/g/g/vg.

So, any opinions on how this might "perform"? I realize this is not top notch but maybe still very nice for the price (in a good way).

Thanks.

That stone is priced very high, in my opinion. I did a search and found this one:

http://www.whiteflash.com/hearts_arrows/A-Cut-Above-H-A-cut-diamond-171969.htm

Even though the weight is slightly less at 1.597 (basically 1.6), it has a diameter of 7.57-7.58mm whereas the stone you posted is only 7.57-7.61mm for a 1.73 ct. So basically, you can get a J VS1, top quality cut with AGS0 cert, the same diameter, for $10,089 (with the wire and PS discount) rather than $14,500.

Oops, sorry. I meant G color, not J.

Not good.

1. $14,500 for a 1.73 J/VS1 does not seem to be good.

2. EGL J/VS1 can be GIA/AGS K/IS1 or can be even lower. Even worse.

3. It has a very poor spread of 6.32 mm / ct. The stone would look like 1.6 - 1.65 ct.

4. 13.8% Crown, 43.6% Pavilion, and 60% Table seem to exaplain 34.8 degree crown and 41.6 degree pavilion, which no one here would recommend.

5. It will "perform", but in a poor manner.

Strongly recommend to keep looking for something better.

It is actually difficult to find a worse stone on-line.

Good luck!

EGL G would be at best H, likely I or J.
EGL VS1 would be at best VS1, likely VS2 or SI1.
In addition to such a cut quality no one cares,
I would still recommend to look for something better, which is not difficult at all.
Guaranteed.

I agree that you can do better. Here is a 1.86 H VS2 AGS stone for $14,750 with wire discount. There aren''t many H stones available right now (on the search tool) between 1.5 and 2.0 VS1 and VS2.

personally, i would not spend $14k on that stone...you don''t say what EGL cert it is but depending on the lab, it could be loosely graded in terms of color and clarity. also the table and depth are far outside what i would consider when shopping.

there are too many exceptionally cut, wonderful stones out there for me to ever really advise anyone to get a potential dud unless it''s something like 1/2 price. and even then i don''t know...i''d much rather have a smaller better cut, aka more sparkly stone, than a big dull rock. i''d advise continuing to research. good luck!

Thanks for the replies. For my education, how did you come to the spread calculation of 6.32/carat? What is considered a good spread? BTW, the HCA said this stone had a very good spread.

First, I read c/p wrong. I thought 34.8/41.6 which is terrible. Now I see you said 34.8/41.2, which is a lot better and may look OK. But without additional information like Ideal Scope, I see no reason for you to stick with this stone. A 60% table can be very beautiful, but not many of them seem to be cut with high standard.

Spread: Depth (62.3% for this stone) can be used to predict the spread. People often prefer something below 62% (something like 61.9 or 61.8%). Some demand below 61%.

I use the weight and the diameter average (divide diameter by cube root of weight) to see diameter per carat. I generally prefer over 6.4 mm/ct (6.45 is nice and 6.48/9 is super), sometimes 6.37-8 mm/ct. But not below 6.35. HCA is very harsh on the spread. There are very few stones that get EX on spread. A stone with excellent spread can only get "very good" on HCA. This stone also gets "very good" ... HCA may have room for improvement ...

This stone would look noticeably smaller than it weighs.

Generally, if you see a socre between 1 - 2 on HCA, you do not have to worry, especially spread. But I would suggest you to find a stnoe that comes with real ideal scope image, which is safer. If you post your criteria (size/color/clarity), people may help locate one for you.

That's sure a nice John Deere you got there. I am particular to Hoovers myself.

tanker, a good spread for me would be more visuals up top...and less depth in the bottom. my super particular anal specs on ring stones are under 62 depth, but i'm kind of a nut like that. however, i would definitely say on this stone you should at least keep looking around and make absolutely sure you can't find anything else that might be better (and i say this because i am sure you can).

I LOOOOOOOOOOOVE the tractor! It's SO you! hahahahah

El Bimbo, that's a PEEEEEEEEEEERFECT avatar you got going on there. It looks really expensive - maybe about $7000! LOL


Oh, and ditto - I'd keep looking - that stone isn't speaking to me, either. I also think you can do better.
