Round Diamond - ASET/Ideal scope picture review (Urgent)

[diaroo]

Dear all,

I am very interested in purchasing a round diamond (FVS2 - GIA Triple Ex. - HCA score 1.4). Only 'minus' I can find in the specs is that it has a table of 58%, all other proportions are perfectly balanced.

As I am purchasing online, I do not have the opportunity to see the diamond in the flesh. Could you help me determine based on ASET/ideal scope pictures attached how the diamond's optical performance will be?

Thank you very much in advance!!!

HCA=1.4 (X/X/X/VG), but the ASET suggests there is some leakage under the table.

HCA=1.4 (X/X/X/VG), but the ASET suggests there is some leakage under the table.

I wonder if this is actual leakage or strong backlighting. This is the issue with ASET and IS that I don't like. A stone with those angles shouldn't have a full ring of leakage like that.

 

[diaroo]

Do you think the leakage would significantly impact the optical performance? How would you rate the optical performance based on the pictures: average, good, very good or excellent?

I am waiting for your expert advice on the stone in order to proceed with the purchase... Thank you for your input!

Bump - Would need some buy/not buy advice asap as I need to pull the trigger quickly...

Any feedback is much appreciated!

I think that the apparent leakage ring is probably strong backlighting. I don't think I've ever seen an ASET for a stone cut to those proportions that showed a "ring of death" leakage pattern like that. I am guessing it is a nice stone, but would refrain from ordering unless there is a return policy in place if you end up not loving it.

Hi,

I am still very much in doubt whether I should proceed with the purchase or not...

Price, proportions, colour & clarity are perfect to me. I just do not know if the aset/ideal scope pictures indicate it is a good or poor diamond?

Any other opinions on the pictures? Thank you in advance for your suggestions/advice!

It doesn't look like a poor performing diamond. Depending on what you're paying for it it could be perfectly acceptable. If you're paying premium signature cut line prices then I might reconsider.

The ring of leakage does worry me in the ASET. Enough that I wouldn't purchase it without some other feedback.

DiamondHawk/Brian Pollard wrote a pretty neat article on ASETs and IdealScopes:

https://www.pricescope.com/journal/what-aset-reveals-ideal-scope-does-not

I would say the so called ring leakage is a result of a white (a more brutally honest way to present an ASET vs a black background).

 

[diaroo]

Thank you very much for all your feedback!

I will request an additional aset/pricescope image, however I don't think they have further imaging available.

If not available I will refrain from buying.

Thanks!

Vendor argues that the table is bright and has a return policy in place.

I have attached some higher resolution pictures of the diamond. I find it very strange that the ring is visible in the ASET picture but not in the ideal scope? Aside from the lighter coloured red ring in the ASET picture the other images appear fine to me?


Price looks like a good deal to me. What do you think: proceed and return if diamond would be a lemon or pass and continue searching?

Thanks for your advice!

You don't have an IdealScope picture. You have hearts + arrows pictures. Neither of those two pictures with "red" in them are the IS, so your ASET is the only picture you have that shows light characteristics.

I had a lot to do with the lighting in that ASET set up. I do not think that ASET image is for the diamond with these proportions.

Garry, in terms of table, CA, PA it seems to fit the wireframe premise (nominal 50-80 used for minors).


The cut-consistency isn't top-shelf by any means - seen in the other images - but the essential table-reflection footprint also matches the wireframe premise of the primary angles in the "perfect" rendering below (with cut-consistency aberrations again acknowledged).

Is it possible someone replaced batteries or bulbs with something over-bright?
