It can be cheap, but much more details are needed to evaluate. Such as, which grading report they use, is it triple excellent or equivalent? Does it has fluorescence? How are the proportions pairing?

I know some people do just aim for carat weight by sacrificing other areas. Nothing wrong with that, it is really a matter of preference.

Colour: yes, D is the highest. But different lab sometimes can have one colour grade difference. No hard and fast rule though, and if there is nothing to compare side-by-side, it is hard to tell sometimes, especially from normal viewing range. Personally I also prefer D, E, F, but I may choose G or H to maximize value.

Clarity: VS1 is good clarity. It is what I prefer personally for mind-clean and eye-clean factor. But if I don't mind eye-clean VS2 too. If you don't mind SI1, you can also go for it as it brings much more value.

Carat: on average I believe 0.3,0.4ct are the common ones in Malaysia. Don't really have sweet spot afaik, but you can consider the finger width if you want.

Budget: It is very possible for you to land on a good 0.5ct colourless VS1 with a 18k  solitaire ring.

Crown: 34-35

Pavilion: 40.6-40.9

IMO, 35 Crown pair with 41 Pavilion needs more clarification in terms of light return, as both are steep angles and may or may not work well with each other. The relationship between a Crown and a Pavilion should be inverse of each other - one towards steep, one towards shallow and vice-versa. Of course, if both hit the middle spot then will be best, theorectically - which is the original Tolkowsky cut, 34.5 crown and 40.75 pavilion (closest you can see on cert is 40.8).

You can consider both none fluorescence and faint fluorescence diamond graded by GIA, as AGS considers these 2 are negligible. Price wise, faint one will be slightly cheaper. Usually fluorescence is blue, if it is not explicitly stated as other colour. Blue fluorescence usually is quite safe, just that some people prefer none.

Other things to look out for is Blue, Green, Mixed tinge and milkiness. These stats are usually provided by the diamond supplier, whereby some locals jeweled source their diamonds from.

Hi, would like to get some of your opinions on the diamond below

GIA: 2201520761

Carat: 0.4
Color: E
Clarity: VS 1
Cut: Excellent
Price: RM6000

I don't know much on pavillion and crown angle, this comes with 41 Pavillion angle and 33 crown angle.

If you just want a typical GIA 3EX, consider Wah Chan, Habib, Tailored Jewel, or Zcova.

2 and 3 to me is no no. I won't buy stones with 41.6 and 41.4 pavilion angle. Very high chance to leak a lot of light. Stone 1 pairing works best with 40.6 pavilion, so another no no from me.

So there is nothing I can recommend. But you can let me know your budget and the 4Cs you are looking for.

If the store is Wah Chan, you can't see any difference from one stone to another inside there. Everything blinks. How I know is based on my own understanding and experience. In fact, you can see two brands... LAZARE at DeGem and Estrella at Diamond and Platinum, and one other brand Solitaire Club by Wah Chan... They won't take 41.4 and 41.6 pavilion angle into their collection...

6k is possible... There is a promotion last month by Zcova. I think around RM 5800 for 0.4ct E VVS2. Comes with 18k solitaire ring. See whether they can make an extension for you or not. One of the founders say mention my name "Yang Kin" can get you additional RM 50 off. So maybe you can try and say that I intro you since I am also affiliate with them... no guarantee since promo supposed to finished already, but worth trying.

Update
Have a look at my renderings using DiamCalc. As GIA rounds up figure, this is based on best estimate of the proportions, which can be rounded up to match the figures on GIA report:

[attachmentid=10314541]

[attachmentid=10314542]

[attachmentid=10314543]

However, I have to stress that this is assuming that the diamonds are very well-cut. If the cutter does not cut the whole diamond good enough, the diamond will have worse performance.

F means Failed I believe. That is a really really really bad ASET.

This is an example of how a good ASET should look like:

In the cases I provided, only diamond 1 looks much more normal... And yet this is just a rendering based on estimated proportions as GIA rounds up the figures.. For instance, a 34.3 crown angle is 34.5 and 34.7 crown angle is also 34.5. BTW, this is assuming diamond 1 has top cut quality, proportions are just numbers that represent a diamond in 2-dimension perspective, we can get this sort of number by averaging the angle of multiple corners, for example, crown angle 1 is 33, crown angle 2 is 35, we will get 34. Cut quality regards to how well and how close each corner is similar to one a another. When one corner differs a lot to another, we will have cut quality issue.

I can only say if you the 0.6ct will perform badly in real life. The 41.6 pavilion angle will leak the light out of the diamond, since the crown angle pairing is 34.5. And I can say in real life, it will be absolutely look "just" like a diamond, with no performance, at all. You can certainly get much much much better diamonds. Drop by KL PJ wedding fair and check things out if you have the time next week.

Nice proportions. If cut quality is good, will perform better than typical stones that you can from Wah Chan. Did you go and compare with their standard GIA stones that is not under solitaire club?

I will render it later. Give me some time.

Pls remember that rendering is based on estimation only. It does not really represent the real thing. Based on the proportions, I am sure the rendered image will be pretty good.
