I'm assuming you didn't see this diamond under the ASET scope? Because based on the proportions I see on the GIA, the diamond won't be a good light performer. It's on the steep deep or top heavy side, which would usually show the ROD (ring of death) or light leakages at the table. The crown angle is way too steep at 36 and the depth is over 62%. So the diamond will also look smaller for its carat weight. Though a 0.67ct is a nice size just under the 0.70ct mark, it won't truly look like a 0.67ct size.

Also the star facet is 45%. Ideally it should be at least 50%. This in a way controls the size of your sparkles. So smaller star facets = smaller fire. I suggest trying to see the diamond under the ASET and it should reveal all the visual issues with it.
OK thank u for the feedback, will look at it through the ASET scope. Thank you!

Hi all.

Can I ask what should be the width dimension of a 0.8ct?
Is 6.01mm small for 0.8ct?

Also, for the table percentage, what's the visual difference between 54% and 57%?

Was offered a piece
Table: 54.7%
Depth: 62.1%
Was thinking if the table is too narrow.

Thank you in advance!

Wah.. the decagons are getting very popular. So many ppl buying them now and I can understand why. lol. The AGS cert itself is already the best available cert (better than GIA IMO), and much stricter than those shady IGI, EGL, etc. ones. Plus the decagon are JP's white series (I believe the decagon is the highest light performing one out of all the shapes). You're in safe hands with JP.. The diamond is as perfect as it can be.
Thank you for your feedback. Was offered it at 5K excluding ring.

Would also appreciate to hear from other members about this as well.

Much appreciated

I'm assuming this if for a 57 facets round shape? The dimensions is about there.
Table size is ok. Though you should look at it in combination with the other facets too, like the crown and pavilion angles. Proportions should also be seen as a whole and not just independently. The depth is abit on the deeper end. But if its for other shapes like cushions, ovals, etc, its normal.

Best is still to use the ASET scope to evaluate it too.

Would the diamonds be getting more expensive? Seems like De Beers raising their prices...

De Beers Raises Diamond Prices Again as Buyers Keep Coming Back

Yeah, I believe its very likely that diamond prices will be up again soon.
In Jan De Beers increased by 5 % - https://www.bloomberg.com/news/arti...mond-prices-most-in-years-as-industry-revs-up
Now they gonna increase again.

The makes and cuts are trading a premiums now while those poor cut (normal triple Excellents) remains illiquid and hard to sell. Goes to show how those high light performing ones hold their prices much better. Lucky I bought mine earlier :)

Same. Lucky I got it earlier too. The price was good that it was almost too good to be true...

Your decagon looks good. JP already has a super tight QC that goes beyond the norm. Everything looks in order (y)
Hi gurus,

Any comments on this diamond, esp its proportion and inclusion location?


The white series proportions doesnt follow the same ideal proposals as the 57 rounds. But they do seem ok to me. I rem in one of their videos, they said its more into light performance based cutting rather just just relying on the proportions. Your feather inclusion is ok (not cutting across the girdle). And yours is a VVS1. If it has issues, it would be a VVS1 liao.

The link doesn't work.. it says ''file not found''

Hi All, would like to seek comments/opinions on below 2 custom cut diamonds I got from Jannpaul. Finally after 4 months! I am intending to make them into a pair of earring.

https://agslab.com/ym-vdgr/en-us/diamonds/104114149054/grading-reporthttps://agslab.com/ym-vdgr/en-us/diamonds/104113632012/grading-report

That's the white series Round 10 and decagon! The AGS certificates are like the rest I see. If it's JP's white series, it will confirm be good. It's even tighter and harder to cut than their SICs. And their SICs are already very strict.

Thank you! I’m just worried the proportion for the 0.381ct one seemed to be less than ideal. I heard that the table size for a round brilliant should be 54-57%. The 0.381ct one seemed to be on the lower side at 52%.

I know the Ideal proportions doesn't follow the typical round brilliance since its a complete different cut after all. It will be more accurate to check on the scopes instead like the ASET and Hearts/Arrows.
