Hello - I''m looking for some advice on this stone, I''m trying to figure out if this stone has good proportions and how good of a cut this stone has, can someone give me some advice or opinions on this stone? I want an ideal / excellent sut stone so is has tons of fire and sparkle - will this stone give it to me?

weight: 3.05
cut: round brilliant
measurements: 9.05 x 9.09 x 5.85 mm
total depth: 64.5%
table width: 60%
crown height: 14%
Girdle: medium
polish: Excellent
symmetry: excellent
cutlet: none

clarity: VVS2-VS1
color: H
Flourescence: faint

it comes with a certificate from DGL - is that a good reputable / strict grader?

thanks for any/ all help!
 
To evaluate the cut of a stone fully, we would also need the crown angles and pavilion angles. At a glance, your stone is deep and faces up small for its size. The strictest grading lab is AGS, followed by GIA. Start by looking at stones graded by those labs.

Here's Lorelei's cheat sheet for ideal specs, but all stones should be evaluated individually.

depth - 60 - 62% - although my personal preference is to allow up to 62.4%
table - 54- 57%
crown angle - 34- 35 degrees
pavilion angle - 40.6- 41 degrees
girdle - avoid extremes, look for thin to slightly thick, thin to medium etc
polish and symmetry - very good and above

If you're looking for something 3ct or larger, you may be best served by directly contacting a few vendors and seeing what they can find.


Good luck!

ETA: This stone at WF is a similar size, but better cut.

Ditto Merc,

Also the diamond is deep and the table large, I am guessing the angles won't fall into a good range either, so if a lively diamond is important, I would pass on this one.

Also do you mean EGL? You can read up on how the grading labs rank here. Also does it have an actual grading report? The split grading isn't usual for these, I have seen little documents which have split grading and aren't considered a reliable indication of colour and clarity.

http://diamonds.pricescope.com/grading.asp

Is the diamond with an online auction, online vendor or store jeweller?
 
The diamond is from on online vendor who is located in Isreal. He sells some things on Ebay. He claims that its a well cut stone and that the stone has a ton of fire.

No the grading lab is DGL - there website is (http://dgl-labs.com). It comes with an actual grading report, I have attached the report.

I''m looking for any more advice or opinions here.

Many thanks

I've never come across DGL before, and the cert is missing some pretty basic info. Any chance that you can get an idealscope image or ASET of this stone? From the info we have, it's not great, and that's the only other way to assess light return. From the little picture on the cert, the angles are off.

The stone is clarity enhanced, I assume that it's priced accordingly? Do you know what sort of enhancement was done?

What are your priorities in finding a stone? Is the 3ct mark a magic number for you?


ETA: There's another DGL that's the Diamond Grading Laboratories in London. Seems weird that there are two.

Ditto. How much is he asking for it?
 
Its priced at $10K which I believe is very reasonsable for a CE stone of this size?

I am looking for a stone that is between 2.7 and 3.0 carats. Very well - excellent cut, eye clean, as colorless as possible and just a sparkler.
My budget is up to $15K so thats why I''m considering enhanced diamonds - natural ones are outside my budget.

It is not. At those measurements the crown angle avg will be 34.9 and the pavilion angle avg is 42.0. It would be only an AGS5 candidate for light performance but the depth is even more concerning.

It 'faces up' like a well-made stone of 2.75ct, not 3ct. This is due to the steep angles and girdle thickness. Reputable cut-grading labs would knock it down several grades on that alone.

While the girdle is listed as 'medium' labs treat those measurements differently. There is a DGL based in London. I have no experience with their reports.
 
In the pic which looks like those number indicate it should look you can see the under table leakage.
No wheres close to being well cut.

I''d pass. Cut doesn''t look stellar and I wouldn''t want to pay for a three carat that doesn''t face up like a three carat.
 
THe seller told me the stone has the following parameters:

Pavillion angle: 41.7
Crown angle: 35.5

I plugged the numbers into the https://www.pricescope.com/cutadviser.asp and the results were:
Factor Grade
Light Return Good
Fire Poor
Scintillation Fair
Spread
or diameter for weight Good
Total Visual Performance 6.1 - Fair

It wouldnt bother me if it looks smaller than a 3ct (its suppose to replace a 2.7 stone I have now) as long as it sparkles well. What do you guys think? It is worth the $10K or should I keep looking?

Thanks for much for the advice!!!
 
Angfrompa,

This stone is far from an Ideal cut and I''ve never heard of this grading lab.
Perhaps you can ask this vendor for actual photos and additional information?

Best!

What we''re trying to tell you is that with those numbers, it won''t sparkle well. It''s not ideal cut. It''s dark in the one photo provided. If you already have a 2.7ct stone, why spend $10K on a larger stone that looks small and isn''t bright?

Thritto, it is what we call a steep deep with those angles and it will leak light and not sparkle well, you can see the leakage in the photo, see Storm''s illustration.
 
All I know is that stone that mercoledi posted made my mouth water.

Could you imagine that in that swan setting from Vatche????

Quadritto? I don''t think that''s a word but what they said!
 
Thanks everybody! I really appreciate everyone''s feedback. I''m going to pass on the stone.

I LOVED that stone that mercoledi posted also, but that stone is $72K. WAAAAYYYYY out of my price range.

But anyone know where I could find a stone like I am looking for for under $15K?

Again thank you all!!!
 
Edit: Unnessecary post as I missed the report :)
