Do clouds in table create cloudines or haziness?

[rockysalamander]

I'll let Gary respond to your inquiry, but offer my own opinion and process for newbies. I think you know all this, but I thought it might be useful to have in one list.

Screening level 1. GIA Excellent is a very wide range that includes some well-cut and some that are not so well-cut. So, start with only GIA excellent or AGS Ideal/Excellent.

Screening level 2 for GIA Excellent stones.
Depth 60-62.3%
Table 54-58% {I prefer up to 37.5}
Pavilion 40.6-41 degrees
Crown 34-35 degrees (sometimes up to 35.5ish with idealscope image)
34 crown pairs better with 41 pav and 35 crown pairs better with 40.6. I like certain 36 pairings personally.

Screening level 3. Run the angle through the HCA tool. This will test if the angles are complimentary or not. https://www.pricescope.com/tools/hca . You can to eliminate anything with HCA more than 2.0. Anything less is worth pursuing.

Screening Level 4. ASET scope image and or idealscope (IS) image. This tells you about light return. Hearts & Arrows images tells you about symmetry.

{if images are not available, certain stones should be eliminated based on the video or other visual cues. 60/60 stones really need imaging IMHO).

At each level, you may be screening out stones that would be fine. But, the idea is to widdle down to those few that provide a high degree of confidence for performance -- then ask for images on those.

I posted a very very compelling stone in your other thread.

Hi Rocky

I must apologise I’m trying to look for your post again but can’t find it! Which stone did you recommend?

Oops. Sorry. That was for another poster early this morning. I need more coffee... If you can remind me of your specs/budget, I can look again.

 

[rockysalamander]

Haha! I found the one my eyes saw this morning. What do you think?

Wow thanks! Stats look
Great tho the first has a black inclusion on the table I think - do they usually give ASET images?

Also with JA are these their instore diamonds ? I was thinking to source via my dealer - just wondering if it would mean he needs access to the same supplier..

You can try with your local guy, but while you wait to get there and hear from him, the stone can be sold. Its really up to you. Yes, one has a tiny ittty bitty inclusion. At VS1, I would not worry about it. Seriously, you'd have to have magnification vision to see it on something so tiny. I'd even live with it and I have access to 100x scopes at work!

Me? I'd online chat with JA right now and ask for holds on both. Then, request IS images on both (they don't do ASET on rounds).

Hi Rocky
The first is sold but the second looks amazing. Based on stats as a VS1 F, the angles and images do you think an ideal scope is necessary?

Thanks

 

[Gav]

Hi all would a medium fluorescence potentially create milky cloudy appearance for This stone thus explaining the relative lower pricing of it?

Very unlikely, and yes the stone should be priced lower compared to a non fluor stone.

IS and ASET scope photo would be helpful.

 

[Gav]

based certificate and on the videos are there any apparent issues with this stone to be mindful of? Thanks

To me no, but the IS will help us see and understand if the averages reported on the GIA are tight or wide ranging leading to leaking. Video looks good, but the IS is helpful. If they can't offer one, I would feel good about these angles. Also has for a H&A view.

Medium flour is highly unlikely to impact transparency. Its generally only at strong and very strong.

Thanks Rocky, based on these angles even if it wasn’t super tight would the leakage be minimal or do you think GIAs rounding is such that there could be a huge impact based on a few tenths of a degree of deviation?

 

[Gav]

Hi Rockt

I just noticed also In the report there is a reference to indented natural. Is this an issue that could mean the diamond collect dirt/oil or create durability issues for the stone itself?

Seems Hard to spot on the video and certificate..

Thanks
Gavin

Gavin until you get the images there is no point worrying about the minor trivial details

 

[sledge]

Agree with @Garry H (Cut Nut).

Hopefully you put the stone on hold so someone else doesn't pouch it from underneath you.

Did you read the post @rockysalamander did that identified the steps? Be wise and follow them! You are at the point with this stone where it APPEARS the stone is good but no one knows for sure. You need the IS (and ASET, if available) images to confirm any additional information.

Again -- if the stone isn't on hold, put it on hold and request the images. Then post the images so we can tell you more.

 

[Gav]

Hi all

Ok will take your point Garry, thanks
Yes am waiting for the IS. They have no H&a for this one nor ASET

 

[sledge]

Dis you put the stone on hold? Both them show as sold this AM.

 

[Gav]

No i think someone else took the first stone unfortunately. However I have asked for IS for 2nd and put it on hold...

 

[Gav]

Meanwhile I have found an alternative stone, the crown and pavilion angle look solid but does this work with a 60 T?

The angles land this as an ideal cut, and even drawing the box around it, the majority of the boxes end up in ideal cut territory. So yes, the angles work pretty well with the larger table, assuming the cut is as good as anticipated.

However, this is what we call a 60/60 diamond as the table is 60 and the depth is nearly 60. It will have lots of white light return but not as much fire/sparkle. Many people love this style and seek them. However, it is different than what you have been searching so you need to understand the difference and know if you are okay with it.

Kind of like red vs blue. Nothing wrong with either color, but some people prefer one or the other.

 

[Gav]

Hi Sledge

Which table are you referring to? I think you may have linked it once but I can’t find the post!

Thanks

 

[Gav]

Also between these two diamonds without seeing the IS can we comment on which one may be superior or is it pointless until we get photos of both ?

 

[Gav]

Hi all just one last note about the 1.31 from James allen - it has been mentioned they are unable to provide H&A as it is not a H&A stone.
Is this anything to be concerned about - I thought all stones have a H&A but does this just mean it’s not a very good H&A or could it have other impact?

I would prefer the one @rockysalamander suggested. First I trust her as she has helped me bunches. Secondly, as I noted earlier that last diamond you found is a 60/60 style and will have more white light than fire/sparkle. Some love that but I do not so I would personally be more in favor of the stone Rocky picked.

But until you get the images, you are stuck as you need those images to confirm/deny rather the stone is what we expect.

Technically all modern round stones has some form of hearts and arrows. The key difference is that when a stone is referred to as a true H&A stone then the 8 hearts and the 8 arrows have near perfect symmetry which make it sparkle more. Without great symmetry your facets change and it effects the cut quality.

Of course it takes more precision and time to get a true H&A stone so not all stones are cut perfect or labeled as such, and consequently vary in price.

 

[Gav]

On a separate note I’ve finally received an IS for the original stone I had posted. This is a lot less than the F VS1 so wanted this as a back up if it was good

 

[sledge]

Do you see the light spots around the center of the stone? That is light leakage and means it will sparkle less.

Not the worst kind you but ideally it's a nice dark red all the way around instead.

 

[Karl_K]

There is over bright back lighting on the IS image causing the lighter areas. It passes the IS test.

 

[ringo865]

Is it eyeclean with clouds and additional not shown? The image, while blown up, is pretty specky.
