tbh i’ve seen all their white series cuts, decagon looks better than the best sic in all lighting conditions, have you seen it outdoors/ white light? Even for the size you’re going for I’d go for the decagon, what’s your options for decagon naturals? I believe they do pre-orders as well
that’s the thing. this sales person keep sharing that the currently SIC diamond is performing better which it does la from what he showed me indoor and from a distance. I have not bring them outdoor and compare. I will revisit decagon again. Not much natural decagon to see. Low stock i guess.

Hi all, I wanted to get an opinion on this decagon from JP that I'm considering. Is it normal for JP to have a diamond dated that far back? Are there any issues with the symmetry? Thanks!

Hi,

I just received my GCAL cert for LG diamond:

www.gcalusa.com/certificate-search.html?certificate_id=330380102

Want to check with the group here if the specs looks good.


Thanks for sharing, wow the new certs are an overload of information, D VVS1 Lab grown is 100% a pickup. And the rave over their white series diamonds are no no joke now I see.

I saw jannpaul collaborated with GCAL:

https://www.jewellerybusiness.com/news/8x-diamond-cut-lab-launches-proprietary-grading-certificates/
https://instoremag.com/gcal-launches-8x-proprietary-cut-grades-with-retail-jeweler-jannpaul/

I almost missed out, GCAL now grades IIA for HPHT. So they're probably going the extra mile to root out blue nuance diamonds and going for the highest material HPHT materials only using a FTIR checker to check boron levels. Cause it's extremely rare to have HPHT in IIA.

Using their example on gcal website; of a super ideal 8x just to compare

https://www.gcalusa.com/certificate-search.html?certificate_id=310650000


That's a crazy scintillation difference lol



The Reflector GCAL uses is much more comprehensive than the ASET, this is how it works


It's easy to see how much light is being returned in the round 10 compared to a normal round. Those familiar to the ASET, RED is prety much RED + Green on the GCAL scope, white is the same, leakage. Now I know why everyone claims their decagons and round10's from JP is so much brighter. Insane cutting precision for 111 facets


I think this is simpler to see to the layman, blue and dark greys are leakages or reflection of low angled light, so yeah pretty much speaks about the brightness of the round 10


The live video fire was very interesting to see, I've seen JP showcase in similar lighting tools of their fire videos but at a more extreme tilt , I think some of the technological tools they use are the same.


You should play the video yourself, The fire and scintillation spectacular in your round 10. I think what's interesting here also you can see not only the superior fire scintillation but even the brightness is unmatched
it's very promising to see much more transparency and the abundance of useful information now
GIA and IGI are sticking to extreme basic information, there's pretty nothing much you can tell from their certifications. GIA even doubled down and pulled away data now:

https://nationaljeweler.com/article...-less-expensive-report-for-lab-grown-diamonds

no more growth type identification etc... you don't even know what to look out for. There's such a huge disparity in quality of the material of labgrowns, or even naturals. Not to mention almost no cut evaluation now that GIA absorbed AGS but don't even utilize them properly



Hope this was helpful, very beautiful stone expected from JP

Went down to Jann Paul and was shown 2 diamonds dated 2020, round brilliant 0.72 & 0.812 carats respectively. Not the white series though unfortunately as they have no stocks for those…

Possible to assist to check if they are of top quality?

0.72

0.812

I asked if they have newer diamonds but they say no. Seems like they wanna clear old stocks…

Was also shown a 0.726 cushion modified brilliant.

Also, is the normal range (like the one I’m offered) less superior than the white series? Mine has 8 hearts and arrows only. What’s the difference? Want to be really sure before I commit!

Thanks for any advices or feedbacks!

Thanks for any advices or feedbacksBoth are looking good. But I would suggest you go R10 or Decagon which perform better than R8. You can custom order them.

Thanks for your input! I have checked with them however they mentioned R10 of this size have been unavailable for more than a year now and they also mentioned custom is more expensive and may not be more superior. Can I ask what’s the difference actually? As my timeline is pretty tight also.

If your timeline is tight, would suggest to go for either one, depending on your budget. JP diamond quality has always been top notch. Performance of diamond is always based on individual. Trust yourself and your eyes.

Thanks for the reassurance.

Would love to ask the expert out here if Round 10 is indeed more superior than Round 8?

Based on paper specs, it should have more fire since more cut. But is up to individual eyes as well. Some will say, wear on finger, big can already.

Decagon is quite a unique one because it will still shine. Unsure what’s the golden ratio. My Decagon is 53% and 63% which is smaller table and deeper. Any senpai to share what will be the impact on the 2 Decagon?

yeap their decagon's or all their white series are cut to extremely strict proportions set for each cut. The AGS aset image is a scan, you can request the ASET photo taken( it's more accurate, the ags scans are always off) then share here again. upload into imagr and do spacing if you cant upload images

I was also looking for White series diamond R10 diamonds. I was served by Avery, and she mentioned that pricing for natural diamonds has been quite inflated ever since the pandemic and it has yet to recover . Hence , it does not make sense to offer me a higher than previously quoted pricing. Although she did mentioned that she can quote the price for me if we choose to custom cut by checking on the available rough the diamond cutter has access to. i am still waiting for it cuz i was looking for F to G color, and well im in no rush too cox im getting this for my next anniv. Maybe you can check with your specialist on the custom cut pricing before you make any decision?

from what i understand the decagon was created with the tightest set of angles, and the industry ideal ranges cannot be used for it. I know jp does pre cut qc even within the set of tight angles as well, which means its best to check the final aset?


Also its so amazing to note that the decagon has almost zero light leakages at tilt angles
Decagon


Ideal cut round


For those that opt for sic here its really to each its own, as sic itself follows its set of tight proportions and nothing compares to it outside in terms of the R8. But their decagon newly launched 2 years back its really just amazing what you can do with science and tech, reposting watch paul video here again if you guys havent watched it

Have you seen the ASET images yourself ?
cuz usually the ones in the cert are just scanned images and best to view the ASET of that diamond in person.
Where you got this diamond from ?
I have seen it myself. I think its a very beautiful piece. Its from Jann Paul. I managed to get some images from the sales person. However, one issue I have is that the diamond was certified in 2020, not sure why its not sold till now
