what do you mean by quality?

diamond got 4C
- Carat
- Color
- Clarity
- Cut

which 1 u talking?

True to a certain extend. Why? Let me give you an example.

Your wife has a diamond ring with so-so cut, so-so clarity and so-so everything, but it is a 1-carat diamond. Her friend has a 0.8-carat ring with tiptop 3Ex, F colour and VS1 clarity. When they compare side by side, for sure your wife's 1 carat will own her friend's cuz it looks bigger and it hits the magic 1-carat number. But when they test for the bling-bling factor, that 1 carat with so-so cut will lose 9 street man cuz it is as good looking as a piece of glass.

But you said carat is important for face mahh, so I thought your future wife likes to compare wan.

But still, don't go too stingy on cut just because you wanna maximise carat weight. Really not worth it one bro.

Ok I understand.

Then my suggestion is to still go for a 3Ex stone but one which is at the lower end of the spectrum. They will still have the hearts and arrows formation, but with defects. Let me show you some images of such diamonds

The price per carat for these diamonds is much lower so you can maximise your carat weight.

Please hang on while I look for the images. Currently on the mobile version.

All these are slightly deep cut, so their face-up size will be smaller compared to a finely cut 3Ex, but they ARE STILL 3Exes. Also note the inclusions in the stones. This is roughly what you will get for a SI1 clarity diamond.

The 4th one is as eye-clean as it gets but there is a huge feather at the edge of the diamond on the top left. This will pose durability issues in the long run as your ring is subjected to occasional knocks here and there, which will propagate the feather on to the surface of the diamond. Once the stress is too much for it to handle, it will either form a crack on the surface or worse, chip off.

I am no way a diamond expert, only sharing the fruits of my research from the net and speaking to jewellers for nearly a year.

It is overpriced man. Furthermore, it is not a 3Ex, as master kambingkoh mentioned. I can say 90% it will not perform well.

I believe they bumped up the price because of its D colour and VVS2 clarity. From my experience, D and VVS2 are really not necessary cuz they are something which you pay for but you can't see the difference! To an average person, D colour and F colour appear just the same, and there is no big difference between a VVS2 and VS2 diamond, if both are certified eye-clean.

So, my question to you is: Why pay extra for something better but is indistinguishable? Also, as master kambingkoh said, always go for 3Ex, unless you want a diamond with an ok-ok cut to maximise carat size. If that's the case, I believe jrrsim can assist you.
