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:

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

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
