Urgent expert opinion required

[Gerrard]

I have been looking at purchasing an emerald cut diamond for a while, I am down to 2 stones and need help making a decision.

Stone 1: http://www.jamesallen.com/diamonds/D-VVS1-Ideal-Cut-Emerald-Diamond-1272590.asp?b=16&a=12&c=77&cid=131

Stone 2: http://www.abazias.com/database/NewDiamondInfo.asp?stock=70484569&flag=ps

My main concern over stone 1 is the 67% table. I like the D color and dimensions.

My main concern over stone 2 is the faint flourescence. Also the GIA grades it as IF but it is advertised in multiple places as VVS1. I like the ideal cut and dimensions.

What do the experts think?

Will I notice the faint flourescence on the 1.34 stone?

Do I go for D over F?

Is there anyway I can confirm the clarity of stone 2 (the GIA says IF but there is a mark on the reference diagram but nothing in the keys to symbol section)?

Many thanks in advance.

What do the experts think? Not an expert on step cuts, but the JA stone looks very nice, you can request an ASET image from them that will help with further evaluation. The numbers alone are not enough to evaluate an emerald cut, so there is no way for us to know what the Abazias stone looks like.

Will I notice the faint flourescence on the 1.34 stone? No, not unless you go in a dark room with a blacklight. In normal viewing, you will never notice.

Do I go for D over F? 99.99% of people cannot tell the difference between F and D colors, except in controlled circumstances, like the grading lab. With a colorless EC, I would base the decision to purchase more on patterning and performance, rather than the color difference of D or F.

Is there anyway I can confirm the clarity of stone 2 (the GIA says IF but there is a mark on the reference diagram but nothing in the keys to symbol section)? Ask the vendor. It is most likely a virtual listing (meaning it is held by a wholesaler and multiple vendors are allowed to advertise it) and could just be that the company that actually owns the stone sent out incorrect information. All of the vendors are just updating their database from that info, not the grading report.

Gerrard,

I actually called in the F-VVS1 at Whiteflash - it is indeed graded as an IF and I have seen the GIA certificate.

I ended up rejecting the stone for a couple of reasons:

1 - I wanted nice wide windmills but I felt that these were just a touch too wide and made the short ends of the stone look slightly out of proportion

2 - The ASET and IS images showed the centre of the diamond to look very dark. I didn''t clarify this further as there was another stone elsewhere that I preferred (smaller but I liked the shape and performance) but I could have discussed the "in real life" performance with Bob. The Sarin did look good, with a crown height of about 13% but the stone itself looked a little disappointing - but again, I didn''t ask for further photographs.

I posted the images in my own EC thread - it''s on page 2 of RockyTalky somewhere.

Will I notice the faint flourescence on the 1.34 stone? You will not see faint flor at all.

Do I go for D over F? Side by side you *might* notice a difference in color, but on its own the F would look just like a D. I would go for the F since I think that D color diamonds are a little *too* white and I wouldn''t want to pay the premium for the D when the F would still be blazing white.

can''t speak to the others, hopefully some EC experts will show up.

Hi Gerrard and welcome to Pricescope!

With the first, the table is greater than the depth - although in some cases this can be ok but it looks to me as if the patterning and angles are off with this diamond. You could request an ASET image from James Allen as this would tell us more but I would be personally inclined to see what else is out there first.

With the second, we need images such as photos and ASET images but as it is a virtual stone, I don''t believe Abazias offer such services. Also don''t take labels such as Ideal Cut too seriously as these descriptions are no guarantee of a well cut stone, particularly with emerald cuts which need careful evaluation.

Fluorescence - with faint you would probably never even notice it. Colour, D versus E - it is highly unlikely you would be able to distinguish between the two grades when unset and even less likely when mounted in a ring.

ASET for the 1.19 - What do people think?

 

[Gerrard]

The stone itself.

 

[Karl_K]

Request the crown height on the 1.19
looks like a bright EC but if the crown is to shallow with the larger table the fire will be down.

 

[Gerrard]

crown height 15-20%. Is that shallow?

Generally crown height over 10% is what to look for. The stone has potential.

 

[Gerrard]

Hi everyone, thanks for your responses so far.

I am seriously considering purchasing the 1.19 stone as discussed in this thread. I''ve been told the crown height is 15-20%. I am waiting for the sarin report to come through but am looking for more opinion based on the information above (see both images inc ASET) - is this a good stone?

Shape: Emerald
Carat weight: 1.19
Cut: Ideal
Color: D
Clarity: VVS1
Certificate: GIA
Depth: 63.6%
Table: 67.0%
Polish: Very Good
Symmetry: Very Good
Girdle:
Culet: None
Fluorescence: None
Measurements: 7.31*5.27*3.35
Ratio: 1.39

Thanks in advance.

 

[Karl_K]

if the ch is over 15% that should make the slightly large table not a big issue and it looks like a bright EC.
The final test will be your eyes.

 

[Dreamer_D]

I like the patterning in the picture.

 

[Gerrard]

Urgently need opinion on the attached sarin report?

Many Thanks.

 

[Laila619]

It looks like the crown height is only 10%?
