Among all these, and limited to only all these few diamonds, I think my top pick will be GIA 6402204160. Reason is that the arrows seem decent enough, the proportions look decent, the inclusions seem transparent enough for my untrained eye, and there is medium blue fluorescence, which in theory can help to negate some yellow tint of the diamond, if any.

Followed by GIA 3455389111. The proportions are decent. Inclusions doesn't seem obvious. Strong fluorescence is not really necessary since it is still a G colour diamond. But it does help to lower down the price.

For both diamonds, I will check with ZCOVA for milkiness, just for peace of mind. They should have the BGM data, whereby M stands for milkiness. B, G, accordingly to the internet stands for Brown and Green. They represent a hue on the diamond, and if my memory serves me right, this hue doesn't affect colour grading, but a G colour diamond with Brown hue is not preferred compares to a G colour diamond with no hue (or something like that). You can YouTube about this diamond hue thing, I think Jann Paul (famous hearts and arrows jeweler in SG) shared before.

For what's worth, engage ZCOVA for assistance. You will need all the assistance you can get because... You have only 4 weeks. Not that you don't have enough time, but if you need time to process through and think through alot, then is another story. Therefore, do keep an eye on the time. Good luck man.

Gemex is just one of the proprietary way to measure the light performance of a diamond. Good to have, can probably give you better peace of mind. Blue Nile Astor collection also uses the same, but their standard might be higher when it comes to light performance to qualify for Astor badge. LUMOS accepts High to Very High to become LUMOS. https://blog.zcova.com/2020/04/02/zcova-in-...-certification/

Lumos is just a marketing term to coin their top picked diamonds. Something good to have, and as far as I can tell, they don't seem to apply additional premium on LUMOS diamonds, which is a good thing.

They might apply a premium if the diamond is stored in-house, but this is just my guess, so take it with a pinch of salt.

You can probably request to talk to their gemologist and seek for his opinion. Personally, I too, don't really like the inclusion because it looks dark.

Hi i visited lavin . It seems their price fluctuates a lot. After few days I visited them the price can drop by 300-400 . They claim due to new stock lower fx rate. I compared their diamond with zcova they said zcova doesn’t not keep stock hence they price might be lower now because fx rate is lower.

Anyway I saw this diamond seems not bad as it doesn’t have feather in clarity. Currently priced at rm3800. Any advice ?

I don't handle alot of diamonds. Just like a hobby, but I don't think fluorescence always exhibit milkiness. There is a BGM rating that you can refer to for a particular diamond. I find that blue fluorescence that is not milky possess good value for money. I personally own a 0.3x CT strong blue florescence diamond from Brian Gavin. Looks decent.

I believe it was refreshed daily.

Lol. Then use diamond screener instead.

Bosses, appreciate views on the stone below. I've checked the cut estimator and it falls nicely within the intersect of both AGS ideal and GIA Ex. Don't suppose the medium fluorescence is an issue.

Also, i've spoken with numerous sales reps and they all mentioned the color gradient drops off steeply between G and H hence they don't sell anything below G. Is this true?

Thanks guys and indeed the link proves that SA mostly BS. The difference is absolutely not discernable even at 10x magnification.

Hi guys, I hav my own 3 carat stone, would like to know which shops would u recommend for the ring setting in KL?

Hi, looking for advice on a diamond with cert as below. Are lab diamonds better than mined?

IGI 522254856
IGI 567343009
IGI 567357119

Thanks a lot!!

Hi,

Intending to get the below diamond as engagement ring.

https://www.jamesallen.com/loose-diamonds/r...ut-sku-16032806

Is this a decent diamond?
Any advice is welcome
Thanks in advance 🙏

what pavillion angle should i be looking at that is acceptable ? 

i couldnt view the zcova diamond link.  any GIA number ?

Where did you get the table?

thanks for this table ! so i should be looking for balanced , around 41 degree. any other particularly data i should also look at ?

if the HCA calculator unable to detect GIA that i put , i need to manually put in the data myself ?

If i buy diamond locally, issit recommended to look at zcova ? any other recommended provider ?

Noted on the proportion

Budget RM 4k-5k for diamond  i think with this budget only can get 0.4 carat  .  0.5 carat all 7k above  it seems.  I seems to prefer color over clarity. i think VS2 is good enuff for clarity as naked eyes cant see much anyway.
Do recommend if you have recommendations!

How long will whiteflash  purchase takes ? as i read, many do not setting if we didnt buy diamond from them.  what would be our options for setting ?

Further more, wanna know is the price cheaper for those ruby, saphhire or non round shape diamond ?  i feel ruby / bllue diamond looks much cooler than standard round diamond.
