Try using https://enchanteddiamonds.com/cut-score-calculator and see which one gives the best result first.

If you want a bright diamond, but slightly weaker in terms of fire, then this one should be great: https://www.gia.edu/report-check?reportno=5181323742

If you want a fiery diamond, but weaker in terms of brightness, because it is cut to abit deep, then this one should be great: https://www.gia.edu/report-check?reportno=5253790836

Personally will go for https://www.gia.edu/report-check?reportno=5253790836 because I like fire more. And D colour is colourless enough so I don't need that much brightness to make it look more brilliant.

Among the 4, these 2 above are the ones I will pick.

Thanks sifu. These are the same 2 diamonds I am considering as well. The only thing for https://www.gia.edu/report-check?reportno=5253790836 is that it will be a bit over my budget if I were to include the ring. Another thing is that this jeweller has limited design for ring setting.

And I found this 2 diamonds from a few different sources. It looks great to me based on the cut score and HCA. Any opinion with the below comparing to the 2 earlier you chosen?
1) https://www.gia.edu/report-check?reportno=2266654278
2) https://www.gia.edu/report-check?reportno=7268765804

Thanks sifu sekalian!

https://www.gia.edu/report-check?reportno=7268765804. This one has good proportions. In fact both also not bad, just that this one better. The 75% lower girdle length will return bolder sparks compared to 80%. If the precision is good, this diamond is worth buying. Just check with the seller and make sure it is eye clean and the arrows are aligned nicely. As for the hearts, we cannot be sure unless seller is willing to share details. But nonetheless, proportions are good. I will take this one if my concerns are answered.

Thanks man! I found another one again and it looks good too (https://www.gia.edu/report-check?reportno=7266400185). Man, I am in luck and have so many choices to pick from now.

Yes. Proportions tell me this diamond is fiery. The shallow pavilion pair with steep crown is excellent. G VS2 is quite value for money as well. This vendor seems good. Who is he or she?

Can you please generously share with us where you source for all these beautiful diamond. Of course after you have bought your diamond.

All of us know that there is no much value for diamond irrespective whether it is GIA or not if later you want to sell them for whatsoever reason. Diamond is illiquid and also the mark up for diamond is extremely high. It is pointless to buy too many diamonds.

Thank You.

Both from Zcova. Both seems awesome on the papers and numbers, but I still have not seen the diamond hearts and arrows and etc. Hopefully can go there and take a look at the diamonds. Between this 2 diamonds, which one u think has the best performance in terms of fire and sparks? I read some of them in website saying if the HCA is >1.0, it is not recommended to use the diamond for ring. Is it true sifu? I only determine based on the score number, but don't know how to read the chart and also determine if is a good diamond (as the score can be misleading).

To be honest, is hard to determine just by looking at the GIA cert and based on scoring system... Really need to get your hand on it and look at the diamonds. My personal opinion. Of course some of them provide all the reporting on the diamond (like Ideal, ASET, H&A images). These can at least help you to determine whether it is a good diamond before purchasing or get your hands on it. As the sifu recommended before, Whiteflash and Brian Gavin has really good diamonds. You can check out their website and you will be amazed with them.

Awesome. I have to give it to ZCOVA, they certainly managed to source some great proportion diamonds for you. They both even score 100% on Enchanted Cut Score. Seems like this company is getting more and more mature. I have just visited their website and I am awed by its usefulness. Their old website is nothing much ,but their new website, as far as Malaysia diamond sites are concerned, they are the champion.

As for HCA > 1.0, I can honestly tell you I also not sure. But then, I will just rely back on the proportions, this is because HCA is a rejection tool, and it does not take into account all the 57 facets of a round brilliant diamond. So my rule is, as long as below 2, I am okay. Of course, that's just me. Other's opinion may be different.

If you want a more balanced diamond, the F SI1 is a better choice. Else, if you want a diamond with more fire, then G VS2. Both stones are honestly great choice based on proportions alone. I think we have to look at the final diamond image to determine which one will be the better choice. Try to get it from them, I am sure they should be able to retrieve it.

As for ASET / Idealscope / H&A, you can try ask, but don't put your hopes too high because usually it is only available for diamonds that are 1ct and above.

Tailored Jewel.

correction... if the hca < 1.0...

How do you know? Sifu in SG also know his stuff in KL.

Ya. The price is still ok. But after looking at Zcova, now I am looking at the ring settings now. Tailored Jewel do not have much choices in terms of ring setting. May be what they shown in their website, that's all? Should I go to their shop if I want to view more of their ring settings?

Oppss... Thanks for the correction sifu! Is <1.0

So how is your quest for diamond?

You can visit their showroom lahh cuz they do customisation as well, but their quality is not consistent. They can do a very good job for one customer but a very bad job for another customer.

Maybe it depends on whether you have faceprob or not.

Of course he knows, he intro me to Tailored Jewel.

Yes, ask for customization if you don't like the designs. Or if you find that a particular design is nice, but the workmanship is not up to your expectation, you may try asking them to create a new mould, but you probably have to pay extra.

What you see on ZCOVA's site should be CAD image. I suggest you pay both TJ and ZCOVA a visit if can. View their ring settings, feel the weight, and ask them whether their ring settings uses nickel or palladium. Palladium is a more expensive metal to use when making the 18k white gold alloy and it is hypoallergenic. Nickel on the other hand, may cause allergy to a small group of people. If you girlfriend has no allergy problem, I think it is fine with either, as long as the price is right. Personally, I think that palladium is more "high class" haha.

In Malaysia, I only know Suen @ Bangsar, iDo Jewellery @ Bukit Jalil, FrouFrou @ KL/Penang uses palladium. If I am sure there are others as well, but I only know these 3 so far.

Woohoo! My little beauty has arrived!





Haven't take out to capture the Hearts, will do it at home later and update my blog soon.

Holy shyte! Quickly update us once you gets home!

Btw, how long it takes for it to arrive here? I wonder if Brian Gavin Black and Signature have much differences between both diamonds... What you think sifu?

Bought last Monday by paying using MoneyMatch and received today. Can be faster, probably Friday, if not because of Columbus Day (US public holiday last Monday).

Difference should be minimal if you buy the more recent diamonds, if there are any. Last year's one (around September 2016) should probably be close enough because the cutters need to "experiment" on existing diamonds first before the end product comes out. Another way to differentiate is to look at the ASET. Black by Brian Gavin should zero green lights at the table area.

Dear Sifu-sifu,

Can you please help me to evaluate this piece of gem whether it worth 10k? maybe some description whether i should go for it...haha...yeah from one of the shops (buy and go).
