This is really helpful to me to get other opinions...of course when I do find the one I would have to bring several family members in to see if it looks ok since I have no eye for this. Honestly, I am not looking for the perfect diamond considering I have no eye for this. I do want a bigger stone, I do have big fingers :-) Can you kindly let me know what you think of this one..me and bf will be checking them out this week. Thanks btw its almost 15,000

From the info you''re provided, all that I can *see* is that it''s deeper than I typically prefer, and that the information provided doesn''t offer crown/pavilion info that would hopefully provide more insight into cut.

Two things I do see that make me a bit nervous:

1. This is an EGL stone, and it''s SI2. Given that EGL lacks consistency on their grading stringency, it''s possible this stone might actually be an I1, and might be lower than F color. If you really want to consider this stone, I''d consider taking it to an independent appraiser prior to purchase to make sure the price you''re being quoted is indeed fair (it may be a G or H, I1 by a stricter lab''s standards, but as long as the price is comparable, fine.)

2. A friend of mine just recently spent $15.5K on a 2.3, J, SI1 stone from GIA. If you''re 3 ct. stone is only 15k (even though it''s supposed to be 4 color steps better than a J), I fear that doesn''t make me feel optimistic about the quality of the cut....maybe not even as a premium cut, nevermind ideally cut.
 
If it''s as-described, there''s no real red flag to see. It appears to be a nice enough diamond.I agree that crown and pavilion angles would be nice though and I lean towards a lower depth percentage as well. Still, it meets the original ideal cut specs. That said, how does the stone look to the eye? Numbers don''t always tell the whole story.

CS, on what do you base this assertion? How can you possibly know that it meets ideal cut specs without the rest of the information?

If the crown angle is 32.5, it doesn''t meet "original ideal cut specs". If the pavilion is 41.4, it doesn''t meet the "ideal cut" specs.

Now, the OP may not even be looking for an ideal cut stone......but decent stones in that range run in the neighborhood of $22-24K. Here is an example......also EGL graded so it stands a chance of being equally soft on the grading.

http://www.abazias.com/database/NewDiamondInfo.asp?stock=31678771&flag=ps - Price is $22379

If I were the shopper, I''d have to ask myself why the first diamond nearly a third less expensive? There has to be a reason, and I''d want to know what that reason is before committing to a buying decision.




I have to disagree about the "red-flag"......I think there is an enormous red flag IF this person cares about cut/sparkle. If not, then no worries.
 
I meant to convey that the depth percentage is within spec for ideal. I assume(dangerously perhaps) that the "excellent" cut that this stone is rated at is based on the GIA scale. If it is an excellent GIA cut, there is no red flag. Cut grade covers angles and proportion.

Also, note that I asked how the stone looks to the eye? That covers your comment asbout sparkle to my mind.

the post says it was certed by EGL...and don't they have their own misplaced sense of cut grading? i would think from what has been posted that the 'excellent' cut grade is from EGL.
 
If EGL doesn''t use the GIA criteria, what criteria do they use? I''m not trying to be contentious, I''d genuinely like to know if they are using some other system for their grading beyond the generally accepted standards...

I''m not sure I understand why you''d assume that an EGL graded stone is according to GIA scale??? This stone is graded by EGL. Why would you assume they adhere to GIA standards?

CS, I don''t mean to be contentious, but there are two issues at hand. 1) how does the stone look to this potential buyer, and 2) what is a fair price for the stone. If it looks nice, great---but make sure you buy it at a fair value price.

I think you also misunderstand the meaning of "red flag". For argument''s sake.....if this stone was good enough to have earned an GIA EX grading report, it''s likely that''s what it would have been submitted for. If this stone was comparably cut to a GIA EX stone, why does it not command anywhere close to the same price that a 3 ct, F, SI2, GIA EX graded stone would?

The red flag is this: If the price is too good to be true, there''s usually a reason. Dealers aren''t in business to make costly mistakes and give away the store.

What dealer in his right mind would sell a stone for $15K if the market for comparable stones is $22-24K?

That is a good question...but in the past before GIA even put their cut grade into place, we have seen ''Tolowsky Ideal Cut'' listed on many EGL certs that people have posted on here...on stones with horrible looking #''s. So franky, I don''t know what grading scale they use, but I don''t put much faith in it...whatever it is.
 
Just out of curiosity, what sort of education goes into being a "registered gemologist?" I''m just curious why you wouldn''t know if and how EGL and GIA cut standards are different??

What does the plot look like for this SI2? Where are you finding all these underpriced stones - EGL or not? Are you looking in the secondary market?

An ISG Registered Gemologist is trained in the identification and grading of colored gemstones and diamonds as well as synthetic gemstone ID and must pass a thorough examination to prove competence. The grading scale ISG uses for diamond grading is based upon generally accepted standards and grading practices. You can learn more about the ISG here; http://www.schoolofgemology.com/


As for what EGL's standards are, I am not trained in the application or interpretation of their standards if they differ from GIA's or the ISG's. As far as I know, EGL's greatest flaws are arguably soft-calling split grades and posting pics of the wrong item on their gem evaluation cards. Do EGL's textbook standards differ from GIA's or are they just not studiously adhered to if the are similar to GIA's? Does the GIA teach it's students to grade by EGL standards if they differ from GIA's? I doubt it. Thoughts?
 
Here is some quick info I found on googling EGL cut grades:

http://www.themeter.net/diamond-cut_e.htm
This first link makes it look as though EGL has their own set of grading parameters. They have their own Excellent cut grade as well. Though it looks like GIA's grading hasn't been updated here on this page.

http://grading.pricescope.com/cutgrades.aspx
This link also seems to follow that train of thought. "EGL USA produce optional reports with proportion based cut grade results (e.g. stone # 7 is called EGL IDEAL PLUS)."

Why would EGL be assumed to follow the GIA cut grade standards? It seems like each lab has their own variation of that, why would EGL be any different?

Thanks for the links. Good info.

I have now been suitably enlightened concerning the EGL grading system after having had my own education on grading rooted in the ISG and GIA-oriented grading systems.
