radiant aset advice please!

[greenspoon]

Hello there,

I am a new poster and posted earlier, but there wasnt much response. I am REALLY hoping someone who is familiar with looking at ASET reports can offer their opinion of this stone I am considering.

Here is the link with the images, I don''t have them saved on this computer to re-post, sorry about the additional click through.

The basics of the stone:
Radiant
.80 H VS1 6.67x4.something, haha, 1.41 L:W, 63.3% depth, 63.8% table, 13.1% crown height (I believe this is good??)

https://www.pricescope.com/community/threads/would-love-opinion-of-this-stone.135529/

There is also the Sarin, IS, and 2 40x magnified images.

I would love to know if this stone would be a like good performer or if I should keep looking.

Thanks!

Hi Greenspoon

Sorry you didn't get much of a response but radiants can be tricky diamonds to judge, however lets see what we can do to help you.

It isn't a badly cut stone but I have seen better. With the ASET, I would prefer to see more red as it is showing mainly green, red is desirable in ASET as this is direct light return. As there is so much green, this implies that the stone needs strong lighting to show a decent performance, it could run out of steam in lesser lighting conditions. The crown height is fine so that would be helpful. I would discuss the stone with WF and see what they think, as you want a radiant which performs well they might be able to suggest something else if it is determined this isn't the one.

Thank you so much for your feedback. I was thinking the same thing. It doesnt seem like there are many comparison images for radiant ASET reports. There are TONS for RB and princess. That is where I am struggling. Do you have a suggestion for where I might find comparison images?

I have seen a COUPLE radiant ASET reports and none of them even come close to the amout of red that is in a RB or even what I have seen for a princess.

Could you also comment about the difference between light return and scintillation? Will light return be an indicator of sparkle and scintillation be an indicator of a "dancing" effect with more color or fire?

Thanks again!

You are welcome!

Give me a bit of time to search and I will try to find some more radiant ASET images for you to see. Also it is usual for fancy shapes to show less red than with round diamonds, what you want to look for is a good proportion and distribution of red with some minimal green, fancy shapes will normally show more green than round diamonds. If you click on the red ASET in my post above, that links you to an excellent tutorial on ASET images and how to interpret them. I would link you to the ASET comparison chart under Tools above right which you can normally access by clicking on Idealscope but for some reason I cannot access that area.

Light Return and Scintillation.

The term light return refers mainly to all aspects of diamond performance, the various components such as fire, brilliance and scintillation collectively. Scintillation is the effect seen when the diamond or the wearer or lighting is moving/ active.

Quoted from the link from the Pricescope Tutorial below.

https://www.pricescope.com/wiki/diamonds/diamond-brilliance-fire-scintillation/

"Scintillation is the intense sparkles in a diamond as it moves. Black and white sparkles of scintillation show well in flood lit or office lighting environments where fire can be totally absent. Under pin point or spot lights fire also adds to scintillation. Ideally a diamond has many pleasing flashes spread across the surface of the stone, with few dull dead patches."

Thank you, I had looked at that link and it showed wonderful progression images for RB and princess ASET images. That is what made me wonder if there was such a progression chart for radiants.

I really appreciate you looking into.

I will also let you know what WF says about the stone. I have not had the opportunity to speak with them about it yet. Very interested in what they say since they have looked at the stone in person.

You are very welcome! Let us know what WF says about the diamond, I found some ASET images for you but am having trouble posting them right now, I will keep trying.

Thanks so much, I would really appreciate it if you post those images. I spoke with WF briefly this morning about the stone. They are going to take the photo with the tweezers again, they think is was taken with a glare on the table that is not showing the contrast bewteen light and dark very well.

Their master gemologist had not looked at the stone in person yet, but was planning to and then letting me know what his opinion was. His initial opinion was that it would have a good deal of sparkle.

I will post what they say after visually inspecting the stone.

I just don''t know if I should call one of the alternates in to compare.

OK, I had the opportunity to speak to WF today. They advised that the reason there was a higher concentration of green than red was because of the L:W ratio. That as you elongate the stone you will loose light return. He said that considering the ratio it is a well cut stone. I personaly prefer a higher L:W ratio and that is one of the big reasons I chose that stone. He had seen the stone in person and felt that I would be happy with the stone.

What are your thoughts? On the ASET images (the two that I have found of Radiants), one was for a more square stone and one that was for a longer stone. The more square stone definately had much more red than my ASET image. The longer one, did have less. I just don''t know if that was a function of the L:W ratio as suggested or if the square stone was just cut much better than the retangular one.

I think I am going to have to stone sent to me so that I can look at it first hand, but would love your thoughts in the meantime!!

I tried to post the photos again but it didn't work regrettably, sorry about that. I know some of us have been having trouble posting images recently.

As to the image of the WF diamond, I have always been taught that shape or length to width ratio doesn't make a difference with the colours seen in ASET. It is sometimes possible an elongated fancy shape stone will show a bow tie across the centre which could mean a dark area in some lighting conditions and viewing angles but apart from that it wouldn't make much difference. If I am wrong, maybe Garry or one of the other experts can advise here.

Here is the link to one of the ASET images I wanted to show you, as you can see this radiant is slightly rectangular but is showing a distribution of red throughout the stone, its not cut to top standards but its a nice radiant and certainly better than many out there.

If you like the look of the stone then definitely take a look so you know if it is for you or not, radiants aren't the most straightforward diamonds to evaluate and really it comes down to the buyer's eyes in the end.
