Quoted this from JP for a lab grown. Which is part of their white series round 10. Is it worthwhile to be going for this or am I over paying for a lab grown diamond?

Diamond Type: CUSTOM CUT LAB GROWN ROUND 10 H&A LOOSE DIAMOND
RANGE: 1.50-1.59, D-F, VVS1-VS1

$7,700 - $8,700 (Inclusive of GST)

Also, both are the same 111 facets for Decagon 10 Hearts & Arrows and Round 10 Hearts & Arrows under the white series. Does it boil down to shape preference or there's more to it?

Hi all, may I seek your opinion on this Decagon diamond? I got quoted a price of $4,900 for this from JP:

Cut: Decagon
Color: G
Clarity: VVS2
Carat: 0.545ct

AGS report

Is the location of the pinpoint inclusion something to be concerned about here as well?

Many thanks in advance!! :)
Is this without the setting or with setting?

Hi all, can I get your opinions on this Decagon?

The ASET image is somewhat distorted but the folks at JP assured us that it is due to the angle at which the diamond was scanned, and that the rotational ASET that they will provide is a better gauge of this diamond's performance.

The other concern is with the rather steep pavilion angles. I noticed that other Decagons have pavilion angles ranging from 40.5-40.7 degrees but this one clocks in at 41.2. Saw elsewhere on this forum that Decagons pre-dating Aug 2021 have their horizontal proportions measured differently, but am not sure if changes were made to the pavilion angles too. Nonetheless, the red center of the ASET suggests that the angle is greater than 40.8 degrees. While I understand that the ideal proportions of a Decagon are likely not the same as with Round Brilliants, this one looks quite different from the others.

My GF prefers this but I want to make sure that the specs are not going to cause us problems when we take it out of the store into the real world.

The Aset is computer generated so the actual should not be an issue.

The angles are not likely an issue but rather required for this deeper cut decagon with a small table.

Thank you for your comments, Miltah. What are the implications of the smaller table and deeper cut though? I have seen pictures of nailhead diamonds resulting from this but it was quite hard to make it out in the store, possibly due to the strong lighting. Should I be concerned about this?

Am also a bit worried that the combination of small table + larger arrows could lead a very dark center appearance. Again, didn't get to see this in the store due to lighting and we were hurrying as it was near closing time.

The other thing I noticed on hindsight is that there is a lot of light returned from a small area around the culet (not exactly a point, but a small, very bright circle), and it can be intense enough to distract from the otherwise pleasing patterning of the Decagon. Not sure if this is normal or specific to this stone. I am trying to enquire if they have anything else in a similar price range but still curious to know.

The numbers point to a smaller looking stone but frankly at 0.5c and below it’s hard to notice the difference unless u have a comparison side by side with another decagon

Even with similar ASETs, each stone does look and perform differently IRL. So if u dun feel good abt the stone then just change it

That combination of a lower crown and steeper pavilion is more towards a slightly brighter decagon, the culet table reflection you're referring to does marginally help to it being brighter, it doesn't really "take away attention" if you consider that it helps bring out the black and white contrast (it'd look brighter overall) but this is very marginal, especially with decagons where virtual facets from all the additional facets is entirely different from normal rounds you can watch how the virtuals are controlled and what it means when you watch this :

As miltah said, if you're going down to look at similar specs with other proportions you should look at them visually to compare one with a higher crown slightly less deep and see what your taste preference is.

Then take a look at their rotational aset that they provide now (Its much better than a static aset). Also AGS scan is widely known to have scan errors as AGS does a 3d scan of the diamond and generate the aset model rather than what JannPaul does which is actually videograph/photograph the actual diamond which is obviously much more accurate.

Request for your JP rep to show and compare them outdoors too honestly it's going to be marginal. it's not gonna be so different like comparing their decagons to top of the line 57 facet super ideal cuts where you can see immediately its immediately brighter and more firey under all lighting, but if you're younger your eyes can be more sensitive to brightness and fire tradeoff.

Yes, like what they others here have mentioned, the ASET image in the AGS report could be distorted based on the way they capture the image. If it looks fine on the ASET scope when you view it physically at Jann Paul, then there should not be much of an issue. Just curious, how much did Jann Paul quote you for this diamond?

Thank you for your comments. We went down today to take a look, under daylight this time alongside a similar carat Decagon. GF preferred this one the other day due to its larger fire and slightly larger size (about 0.05mm larger than the other one, a 0.434ct).

As it turns out, it didn’t look overcontrasted like we expected it to be. Interesting thing we learnt is that the smaller table size on this 0.432 makes the flashes chunkier. Can be seen when comparing the ASET images too. The one with the red center has a smaller table than the other two, and it shows a lot more contrast (blue areas).

We were quoted $3450 for this 0.432ct Decagon. The other two in the ASETs were $3350 and $3400, both 0.43's as well.

In the end, we ended up not getting any of them. We got really lucky and snagged a 0.495 that came in recently. Had to stretch our budget a little bit, but for a lifetime purchase, I think it was definitely worth it. Could see that she really loved this one. She was a bit sad that although she liked the White Series diamonds a lot more, she had to give up the chunky fire of the 0.52ct SIC that she saw. This helps to bring back some of that nice, chunky flashes. :)

I got quoted lab grown Round 10 H&A - 1.02 caret, E, VVS2 for $4.4K.

Here's the AGS report: 404051672034 (can't post link due to insufficient privileges

any experts can advise if this is a good buy?

There's actually not much advise to be given.

Their lab grown are the exact same quality as their natural, as long you and your partner are ok with 'lab grown' diamond, there's nothing to pick on.

If you’re comparing prices in the market honestly JP has a really competitive pricing for the labgrowns especially as a White Series diamond. If you’re comparing to the round brilliant 57 facets, you’ll probably see a price diff cause of the labour cost etc cause its 111 facets but do note that majority of the industry labgrowns are IGI certified also. Which basically means they are much lower grades than its actually shown on the cert if you compare to GIA/AGS certified diamonds. JP also guarantees their labgrowns to have no off-hue tint and type-2A which is actually the best possible labgrowns you can get! There's actually diff growth method and it could become green/blue/brown hue but you can research more into those specifics it gets really technical. :oops:

I've compared the sample off-hue that JP has in their store and the labgrowns are really the same type of hue as their naturals which are usually yellow (clearest). I honestly can't tell the diff at all from the lab vs natural. I’ve shopped around to compare of course but I’ve never heard any other SA tell me these things, really respect the extra mile that JP goes to make sure we know what we’re getting and their patience cause I was there a few times already hahah. My husband gets nervous whenever I see JP's new instagram post. :s22:

If you're price checking online retailers they usually carry all sorts of diamond thats why they have so many listed but you should take note of the unnatural hue cause some can be blue/greyish. Also remember that the cuts you see online from JA/BN labgrowns are just the normal 57 facets RB which looks quite diff from their WS range which are a lot more sparkly and brighter! To check the performance you can ask for an image of the ASET to have a better look too. They make nice keepsakes too hehe.
