thanks alot.

so is it safe to say if i were to look at 0.3ct, then E VS1 and its surrounding will be great starting point for discovery?

Well, 0.3ct onwards is rather common, so it's a good starting point. For colour and clarity, you can try to explore various range and see what is your preference. These days, I see more people aiming for higher carat weight while lowering colour and clarity simply because carat weight is the most eye-catching element.

Thank you so much ! I just made my purchase with the choice you recommended

I've looked at your facebook for ring settings, do drop me/pm me your number and quotation for Ring Setting 2 measurements ring size 9 (47.7mm-15.2mm) 18K white gold and I'll look for you once the stone arrives.

Hi. Can you give me your opinion about this diamond? And is the price reasonable?


Thank you for your help!

36.5... is abit out of my own preference. The dimension may be slightly smaller compared to other well-cut 0.4ct, but we are talking about 0.0x mm differences... So it is actually nothing significant.

What I read about steep crown diamond is that the fire of the diamond is good.

The arrows are slightly misaligned, but not too significant.

Price wise, not bad for a brick and mortar or online jeweler, considering the service they can provide.

Hi!

I've bought from Zcova before, and honestly, they do have the best prices in the market, they give you the best diamond your budget allows.
They offer a great service, you'll receive your GIA certificate in case your wondering, so it's a safe choice.

I totally recommend buying from them.

Hi guys I requested for the GIA cert but she mentioned now they cant reveal it due to security reasons. However from the website they do show it but masked the 1st few numbers. I tried using the HCA tool but maybe Im not sure how to read the cert. Based on the below depth is 59.1, table is 60%, crown is 33 degrees, pavilion is 40.8 degrees, symmetry should be excellence and measurement (w x l x d) is 4.36 x 4.38 x 2.58. Did I get this right?



I like to get sifu to analyze between the above and the below. Price difference around 400. Thanks guys!

Additionally, where will you guys recommend to do a decent 18k white gold ring setting? I felt the setting Im being quoted at 2.3k is a little too high. The advice I got was there's a risk involved if go to other jeweller as they might not handle the gem properly or maybe even short changed me with another lousier ones. Any advice? Much thanks

Make sure the jeweler note on the invoice the diamond inscription. When collecting, double check on the inscription and make sure it is the same.

As for not handling properly, usually other jewelers won't responsible for anything bad that might happen to your diamond when mounting the stone, if the stone is not buy from them. SI2 with feather inclusion as the main inclusion can be a little bit risky, if you ask me.

the diamond inscription refers to the GIA cert lasered on it right? I read that can be duplicated as well and the safest is actually to request for an inclusion diagram and compare it against the original because inclusion is like the DNA of the stone i.e. no 2 stones will have the same inclusion location. Sounds more fool proof

Yeah that's true on the handling. But why the particular risk on feather inclusion though? never understood the feather/crystal characteristics of it

So far I only know reading laser inscription is the most common way. As for requesting for inclusion diagram, I have never heard of it honestly, and to compare it against the original stone probably means the jeweler will need to show you where the inclusion is on the stone against the inclusion diagram. While some jeweler may have high magnification tool to do that, not all may have it. And not all salesperson will be trained to do that as well. Also, mounted diamonds (already put on the setting) are harder to match against any inclusion diagram because inclusions can also be at the bottom of the diamond. To add on, not all certificates have the inclusion diagram. Usually for GIA, diamonds below 1 carat will only get a dossier without the inclusion diagram.

Personally, what I will do is actually similar, but more like my own personal way. I will try to identify the Arrows on the round brilliant using a Hearts and Arrows scope and look for any tiny details on the stone, such as how well the arrows are formed, any slightly obvious inclusion that I can see with the scope, etc. Mind you, sometimes "inclusions" you see may be just dirt or dust, therefore I will just remember how well the arrows are formed.

While the inscription could have the possibility of being tampered with, I will think that it will be more common on higher carat weight, higher colour, and higher clarity stones. If someone wants to cheat, the profit margin should be significant enough for him/her to do/risk that.

This also made me Google abit and I found that recently lab grown diamond is also part of the scamming process, whereby they are being submitted to GIA as natural diamond.

At the end of the day, there is no 100% foolproof way. You cannot submit mounted stone to GIA for re-evaluation. You can try find independent appraiser, but you will just have to take their word for it, and I don't think will have much help if your jeweler return policy is only stating that grading report mismatch against inscription on girdle. So, the safest way is to buy from a reputable jeweler and let them do everything for you under one roof. This may reduce your risk.

The risk on the feather inclusion is because SI2 is considered a borderline clarity and feather inclusion simply means crack in the stone. And with feather inclusion as the main inclusion, there can be a possibility that during the mounting process, where pressure is applied, the crack might unfortunately get worsen. Hence, risky.
