Question for Ellen - considering 1.39 G VS2

[arbitrageur]

Hi Ellen,

I''m considering purchasing a 1.39 G VS2, also an ISEE2 like yours. I was wondering if you would be willing to post your helium scan results (or GOG link), since it sounds like you''ve got one of the tightest cut G VS rocks on here. If you''re not comfortable publishing this publicly, I can give you an email address. I couldn''t figure out how to get the PM function to work.

The one I''m considering has a 34.09/41.01 CA/PA combo with LGF 76.9%. I was wondering if this stone might be a little dark.

Other specs:
Table: 55.6
Depth: 61.4
Culet: 0.4

I am sure Ellen will be along soon....

I don''t think you can post your email address and we don''t have a pm function on here.

I am not Ellen. But I know she is willing to publish her stone. It is a super stone among the best. You can look at the 3D scan at http://goodoldgold.com/diamond/1897

The one you are considering is pretty close to heres such as table and lower girdle length.

If it is from GOG:

1. Check the scan mode. Sarin mode almost always add 0.04 degree to pavilion angle, and 0.1 degree to crwon angle. Subtract 0.04/0.1 if sarin mode, which is always closer to AGS data. I have looked at many examples at GOG. Sarin says 34.28/41.04 and Helium says 34.18/41.00 for the one I purchased there.

2. Tight cut - It is true her stone is very very tight. But now I am convinced, thanks to Garry, that c/p variances can also come from the table tilt (as far as GOG stones are concerned), which does not affect the light performance. Take a look at "Measurements as per Octonus theory" in helium data, which shows the table-tilt-adjusted C/P angles, which is almost always very tight (< 0.1 degree variance).

Can it look dark .... ? No way. Should be a very nice one.

 

[gontama]

Note 1) Discrepancy between Sarin and Helium does not mean that GOG data is not reliable. They are very good at these technologies (I am under the impression that it is no less than AGS). It is an inherent limitation of each technology. They are the only vendor, as far as I know, who provides that much information on each and every stone.

Note 2) C/P variances of stones offered by other vendors may also come from table-tilt. It may not be only GOG stones. But they are the only vendor who provides the data (as far as I know).

Hi arbitrageur,

I see Maise and gontama have taken good care of you.

I'll just reiterate what gontama said about your stone possibly being dark, no way. It should be a very bright, yet firey diamond. They cut a gorgeous stone.

If you want to know anything else, just ask. And let us know if you get it!


p.s. Thanks gontama.

Thanks Gontama, Ellen, and Maisie,

I received the ring today, but now I''ve got a question about the setting of the stone. During the setting process, are the prongs heated and bent into position? If so, should any of the metal from the prongs be melted onto the diamond? At first glance there appeared to be "glue" underneath one of the prongs. Under a 10x loupe, it was melted metal from the prong in the 1200 position. Is this normal, and it will possibly damage my stone?

BTW, all of you were correct. The stone is tightly cut (maybe not as tight as Ellen''s) but it is nice. The only thing that might detract from the beauty is the melted metal under the prong.

 

[gontama]

Congrats for the beautiful ring arbitrageur.

I do not think the metal is heated. May be a little but not to the point where it gets melted. Magnified pic may help experts to make sound judgment. Heated metal, if so hot and melted, can damage the diamond. But I doubt it is the melted prong/metal you see on the diamond, though it is probably something that has to be cleaned. A skilled appraiser will be able to tell what it is. I just cannot believe it is the melted metal. Hope some one will chime in.

 

[gontama]

By the way who set the diamond? Was it GOG? If so, you can call Jonathan or the setter. They would do everything necessary. If on the other hand some one else set the diamond, you can still call the setter. I think you will have the complete ring appraied for the insurance purpose. You can discuss your concern with the appraiser too. Hope this gets resolved soon.

There is a name for that, I think. I know I read a post from one of the appraisers on here about it, and it shouldn''t be there. Let me go looking and see if I can find that post.

In the meantime, the ring is just gorgeous!!

 

[Ellen]

Well I can''t find it. But it''s just metal that should have been snipped away and smoothed up after setting that wasn''t. It won''t hurt anything, but if you can see it with the naked eye and/or it''s catching stuff, you''ll want to have it fixed.

If it looks like glue you are most likely seeing a reflection of the prong within the diamond under magnification. I have magnified photography of the prong and the original picture file. We do not see any excess metal in the picture. I do however see a reflection on the prong itself as well as a reflection of the prong within the diamond.

 

[strmrdr]

sounds like a bit of polishing compound if there is anything there.
It looks just like your talking about.
It will go away next time its steam cleaned.
It can be very stubborn to remove and from what Iv seen most rings have a little of it in some place out of the box.

 

[Ellen]

Well, you''ve gotten three posts with three different theories. Feel better?

However, the guy who made your ring, and who has the magnified pic, most likely holds the correct one.

Yeah, I tend to trust the man in the suit. I believe he is correct, and I''ll have another set of eyes look at it with me on Monday.

Greetings arbitrageur,

Please keep me informed on it through email as I don''t get a chance to check here as often as I''d like. Glad to hear your satisfaction with the diamond.

Kind regards,
Jonathan

Well.... I had my second set of eyes look at the ring and it looks like you might be right Ellen.

I''ll post pics to see what the experts think. Is it possible excess flashing on the prongs from mounting the stone?

Another shot -- table view.

gontama,

Yup... I didn''t want to disclose the vendor at first, because I wasn''t sure if the forum posts would be as candid. I''m hoping Jon will take care of me. Its Monday, so I haven''t been able to speak to anyone. Ever seen anything like this?

 

[arbitrageur]

Great news.... I just got an email from Jon (on his day off!) and he''s more than happy to take care of this.

 

[Ellen]

Just saw this. Glad to hear, but not surprised that Jon''s going to fix you up. Please post some hand pics when it''s done!
