Thoughts, I know I know

Now I understand the reservations on EGL certs, I've been looking and one particular stone which I haven't unfortunately seen in person. Anyways can anyone give a fair value, I mean considering it will be a couple grades lower compared to a GIA grading?

10k, maybe even far less.

It is not even EGL-USA. It is graded by EGL-Canada

EGL USA/Canada is probably the best out of all the EGL named labs out there. If this were GIA or AGS graded, at best a J VS2, at worst, maybe a K SI1 (I would be conservative and go with the K SI1 for price cross checks). Have at it on James Allen, B2C or Blue Nile for comparable stones at that same carat size with these colour and clarity characteristics.

That stone looks like it's slightly less than a 60/60 diamond so potentially more brilliance than fire. But I can't get a HCA score for it. HCA is telling me that the stone may have a dangerously thin girdle based on the measurements in that EGL Canada report.

Still isn't a stone that I would ever consider purchasing for my wife.

Selected: 62.5% depth, 57% table, 35.5° crown angle, 41° pavilion angle
Light Return Good
Fire Good
Scintillation Good
Spread Very Good
HCA 4.0 Good - Only if price is your main criterion

ugh. horrible.

Hmm, those numbers don't add up then on the report. EGL Canada give a total depth of 62.5% but yet when one adds up the pavillion, crown and girdle %'ges, you get something less than 60%. On most other reports I've seen, at least when you add up the girdle, crown and pavillion percentages, one gets at least within ballpark (say within 0.2%) of the total depth as reported.

Thanks for the info very helpful so far. I'm very confused now regarding the measurements and proportions and how they don't add up? I received a video, I hope someone can comment on it in relation to the certificate. https://vid.me/uYvx

The angles are not good together and it is too deep.

These are measurements to help you stay in ideal cut territory with a GIA excellent cut stone.

table: 54-58

depth: 60-62.3

crown angle: 34-35.0 (up to 35.5 crown angle can sometimes work with a 40.6 pav angle)

pavilion angle: 40.6-40.9 (sometimes 41.0 if the crown angle is close to 34)

This is what I mean, how far off could the measurements be? It just seems crazy to be off by the much?

I don't want to beat a dead horse here but the vender has given me another option. Cert is attached so based on the above info what do you think a fair price would be to take a chance on this new stone. Keep in mind vender is allowing me to return with no questions asked if I do not like it

 

[bmfang]

Cripes... this one's got an even thinner girdle than the previous one!

I'd still steer clear because if the girdle is that thin, you could run the risk of damage to the stone.

Is your vendor unable to source GIA, AGS or even IGI graded stones for you?

 

[diamondseeker2006]

I can't see that file without downloading it to my computer, which I'd rather not do. From bmfang's post, I gather that the girdle is very thin or extremely thin?

You need to switch to GIA, seriously. You are not saving money by going with a less reputable lab.

 

[Geezwiz]

Can someone explain the calculation to me? To me it reads thin to medium?

 

[diamondseeker2006]

Nothing is wrong with thin. Anything below thin will not get a GIA Excellent cut grade and would have an increased risk of chipping.

 

[flyingpig]

what do you think a fair price would be to take a chance on this new stone.

-2 color grade, -1 clarity grade= 2.12 I SI1 = 14k
14k - appraisal fee (+shipping) - GIA new report fee (+shipping) - risk taking cost - cost of inconvienece = 10~12k

 

[Geezwiz]

I haven't negotiated at all yet as I'm obviously still on the fence about it. I'm in Canada by the way so this plays a factor in price. Initial quote is 17000CAD to my door including taxes(13%) so pre tax and in USD about 11100. I'm just going to see if he will come down from there.

-2 color grade, -1 clarity grade= 2.12 I SI1 = 14k
14k - appraisal fee (+shipping) - GIA new report fee (+shipping) - risk taking cost - cost of inconvienece = 10~12k

These are the specs I was aiming for in a GIA stone anyways.

 

[flyingpig]

I am also from Canada.
Being in Canada is not a factor in price. Diamond prices are based on US dollar. So it should be US price x current exchange rate (NO MORE NO LESS)
17k CAD is more like 12.7k USD.
In addition, even at 10~11k, I would not buy a EGL stone.

EGL specifically targets inexperienced buyers who think they can find a discount or who are ok with "good enough" stones. Their reports are worthless

Good luck.
