Good stuff -- glad to hear this is working out for you. Thanks @whitewave for jumping in to help a forum member. That's cool of you. While I'm sure Danny is an upstanding guy, please put some precautions in-place. Always better safe than sorry.

@DannyD_diamond, please continue to push IDJ to give you those advanced images so they can be analyzed prior to your arrival tomorrow. And no offense on the above, just looking out is all.

Lastly, post some videos and let us know how it goes.

Sledge np worries at all. Sorry for the delay in response. im actually not going to make it out there on Friday but I have talked to idj and white wave has as well and everything is yet. We have also chatted directly and I have built a good repor with white wave, I already can tell I trust her opinion very much! I actually was sent 2 images and GIA on the stones as well

I personally don't like that twinning whisp running all the way across the stone. In some areas, particularly around the 3 o'clock position (in the video -- twist & rotate around) you can see what looks like some black areas on the table.

It could be because it's so zoomed up. But I'd look at this stone very carefully.

Also, there is some symmetry issues. I think these will be more apparent in the H&A images.

I do want to look at the F in person, and the G and then I told Op to have yekutiel pull a 3rd for good measure.

@DannyD_diamond I'm not sure what all you are trying to post upstream. But essentially I see the GIA cert for the F stone a few times and a video link for the F stone (that also has a still picture I posted above, and has another link to the GIA cert).

I haven't seen any information on the G stone. Nor any information on the 3rd stone that you and @whitewave have mentioned.

On all 3 stones, you need to specifically ask Yeukitel to provide you an ASET, idealscope and hearts & arrows (H&A) images. He normally does this with both white & black backgrounds. Also, I would be asking for a detailed SARIN scan of each stone so that I could look at all the actual values of each facet to determine if anything was out whack. For me, this is a major perk of buying from someone like IDJ.

If you aren't aware, the values we see reported on GIA certificates are rounded and averaged of all the actuals. Those small differences can sometimes be meaningful when finalizing a selection.

When you get the above data, please post for us to review.

Also, not sure if Yeukitel will have access to this stone as a 3rd option, but it may be a little sparkle bomb with that small 55 table and 35/40.6 combo. I'd like to see a photo to see where the actual LGF's fall -- hoping closer to 78 so they stay somewhat fat.

One concern I'd have is the pavilion depth is reported as 42.5%.

Mathematically, it should work out as: tan(40.6)*50 = 42.855, which would then be rounded to 43%.

Of course, that doesn't take into account the culet. While GIA reports as none, it could be a non-meaningful number like 0.03%. In which case you have to adjust your mathematical formula as noted:

[tan(40.6) * (1.00 - 0.003)] * 50 = 42.726, which would then be rounded down to 42.5%

Another potential reason is GIA rounds pavilions to the nearest 0.2 degrees, which ends up in an even number. So a reported value of 40.6 could mean an actual value between 40.5 to 40.699.

If the average came back at 40.5 then you'd get: tan(40.5)*50 = 42.704, which would be rounded down to 42.5 on the report.

Of course, to get an average of 40.5, that would also mean at least one or more of your actual 8 pavilion angles are < 40.6 as well. Something the detailed SARIN report would confirm or deny.

hi Sledge. I am not sure why the G isn’t showing. Let me try again

Hate to be a pain, but are these for the F or G, or are they mixed? It'd help if you separate them and label accordingly.

Also, did he give you any hearts images? If not, ask for them.

Eye clean or not, that massive wisp across the table would a deal breaker for me.

The diamond is zoomed so large you can read the GIA number on the girdle, so the inclusions, which appear to be clear, are greatly exaggerated.

It may very well be eye clean given the sparkle and scintillation factor and needs to be seen in person before ruling it out.

It seems to me it’s likely 50x magnified so I am suspecting it is eye clean. If not, and it if affects performance, well we have others to choose from.

I know. But knowing it's there would be enough for me to rule it out personally. Mind clean!

I don’t have a lot of time other than to say the .90 F SI1 is phenomenal. You can’t see the twinning wisps at all, not even under 10x magnification. They don’t affect the stone’s Performance at all and it’s a complete sparkle bomb.

What a great update @whitewave! Thank you for posting the pic and taking the time to run over there.

So you couldn't see the whisps under 10x magnification? Was you able to look at the stone in different lighting conditions? Did it perform equally well in each lighting type?

The F certainly sounds promising. Hey @DannyD_diamond, did IDJ ever get you advanced images on the F stone? I'd love to see them if so.

Whitewave is absolutely awesome and what a pleasure and cannot believe she was willing to do this for me! I will post the additional images they provided me with.

@sledge I would be more than happy to own this diamond. It was a great performer.

I wish I had gotten better pics.

The F is sitting crooked in a setting— keep that in mind.

I would like to ask you guys since I did come across another potential stone that we did not discuss before white wave went in. But would you guys be concerned about this? all the grading and dimensions check the boxes to my knowledge but not sure if the plot is a little too “busy” ED690575-8A52-4EEC-B92F-2CE12CC5602A.png

Come on - just buy a stone! I know the feeling having just gone through the process myself, but you’re down to variance that is unlikely to be even visibly discernible - just pick one and move to the next stage! Is there something you don’t like about the stone whitewave recommended?

An SI2 with that plot might well not be eye-clean, so you would be trading that against a bump in size.

IDJ has return policies that allow an inspection period, doesn't it? If so, confirm their Returns processes and any costs and you would be safe to buy the one that whitewave checked out, to check it out for yourself :)

You could also ask them about any upgrade policies they might have - you could always upgrade in the future.

Now now - a diamond is an expensive purchase and it is a leap of faith to 'buy blind' off the internet, and we are not all in the position to just splurge four figures on something that might not be perfect or exactly what we are looking for, so we must not chastise those who need to gain confidence before taking the plunge.

If you read that as chastising, then you misread it.

I was empathising with being in the same position - it can be hard to take the plunge.

The stone white wave looked at is what I’m going with if I go with a 90 and a halo, as I’m exploring the idea of going with a hidden halo and wanted to see a bigger stone.

Cool - is the 0.9 on hold?

Good luck choosing - I enjoyed learning about diamonds but I definitely got to the stage where I’d done so much research that I couldn’t decide!

If you’re buying online you would still have the option to return if you changed your mind..!
