Round diamond with twinning wisps and 59% table?

Hi all, we’re looking at a 1.3ct diamond, H colour SI2 clarity rating, no fluorescence. Its cut proportions are in line with what is recommended on this site, except the table is 59% (I think the maximum recommended on here is 58%?) and the depth is 60.7%. The inclusions are about 5 twinning wisps on the outer facets of the diamond if that makes sense (the front of the diamond, but not on the table). I have watched the super magnified video multiple times but I can’t see any cloudiness or anything like that. I have included a photo, sorry it’s not amazing quality, the video was much better quality but I can’t seem to post it here.

My question is - is the table size and the twinning wisps likely to impact light performance, or cause any haziness?F1049BDC-E83B-4449-BD4E-BBC026DD6ABD.jpeg

EDIT : here’s a Video

I should add that I have already run it through the HCA tool and it scored 1.1
 
It looks cloudy and not crisp to me.
 
Post the GIA report please so we can see the clarity info/plot/etc.
 
It's very hard to see anything with the video moving so fast. I can see the inclusions on the pavillion side. Do you have a face up photo? Can you share the crown and pavillion angles? I'd like the see the arrow heads better. I think I'm seeing extra darkness in the crown near the arrow heads but it's so fast I can't be sure.
 
I found a larger, clearer video if it helps and a face up photo

Since it's an Si2 with twinning wisps as grade setting feature (listed first under Keys), and since there are additional twinning wisps and surface graining not plotted (Comments), there is an elevated chance the stone has transparency issues.

During your approval period you would be well advised to get a consultation from an independent expert.

Transparency issues can be subtle to the untrained eye.
 
Though the angles are ok, the table is large, making the diamond a bit shallow, and, with all the clarity characteristics, on close inspection the diamond doesn’t have the wow factor. I believe that, as I said earlier, it looks cloudy rather than crisp. Maybe you would notice in real life with regular viewing, and maybe you wouldn’t. You created a previous thread in which you received some lovely suggestions. Perhaps you could check out some that were recommended in your previous thread.
 
The dark spots over the arrowheads are a concern, to me.
Center area (under the table) appears a bit dull and mushy looking.
The arrow shafts don't seem very uniform...wonder if this is a underlying symmetry issue.

Some alternate options to consider:

It's an ACA - the "one and done" solution!

Very nice example - the IdealScope isn't perfect, but I would call it "very good" (acceptable at the minimum level).

Crystal at the 12 o'clock position (it looks like multiples because of facet reflection) over the arrowhead may be able to be completely hidden by a prong, much smaller crystal near the base of the arrow shaft down towards the pavilion.

This one might be iffy - twinning wisps appear to be consolidated over to the 9 o'clock position, but there is no clarity plot on the report, and the bottom portion of the diamond isn't visible in the rotational view.

Here's the link to the PS search that I used:

I would reiterate what others have said here. Si2 is a very tricky grade these days. In many instances Si2s aren’t eye clean and the ones that are have transparency issues. The twining wisp is the Clarity setting grade on this stone. I like twining wisps but on Si1 stones. There they can be diffused in nature and harder for the eye to catch. It’s hard to tell from the videos whether this stone has transparency issues. Many times, post processing like contrast adjustments can hid the milkiness of a diamond. If you feel strongly about the stone, I’d recommend having it professionally checked out with an appraisal. @denverappraiser is an excellent option. Ideally, the appraiser would have non-milky diamonds to compare this stone to.

Good luck!
 
Thanks all for your suggestions and feedback. I agree that the arrow heads looked a bit off but I thought maybe it was just my interpretation. Good to know you also see it. James Allen did say that this was eye clean and the cloudiness shouldn’t be a problem but who knows how forthcoming they really are.

Thanks also for the other diamond suggestions. We live in Sydney Australia and it’s proving really difficult to find a reputable jeweller who will allow you to bring your own loose diamond and have them set it in a ring. Apparently this has only become an issue in recent years as their insurers won’t cover them for damage of your diamond. Hence why we were planning to buy through our jeweller, who can also access James Allen diamonds for the same price (in some instances their prices are better) but they don’t seem to have show the whole catalogue. Will ask if they can get specific gems in for us!
 
@someperson what is your max budget for just the loose diamond from JA?
 
Is your dealer able to call in this one?
It's an AGS Triple Zero, which are better than a majority of GIA Triple Excellent, due to stricter criteria. Plus it should retain a lot more value, being a VVS2.

Outer diameter is 6.9mm compared to 7.0mm of the SI2, which is indiscernible to most people...a size difference usually isn't noticed until at least a 0.2-0.25mm increase in diameter.

Here is the comparison (SI2 on bottom, and keep in mind the zoom rates are slightly different between the two, so they are not a direct representation of size to one another):

Just in case you are interested in making enquiries with other jewellers in Sydney, here are two in the City:

Waldemar Jewellers: https://www.waldemarjewellers.com.au/
I used them last year to make custom earrings and pendants and am happy with the results. They normally prefer to source the diamond for you but they let me bring my own diamonds last year to set due to pandemic and wanting to give workers work during that time. Not sure if they will still do this but you could check if interested.

Troy Clancy Jewellers: https://www.troyclancy.com.au/
Troy was the head jeweller for Cerrone before setting up his own business. Website FAQ says clients can use own gemstones but they need to check gemstone before commiting to use. I have not used this jeweller before but I'm considering them because I have some diamonds I want to use for multiple jewellery projects. Reviews look good and say prices are fair.
