Here is the same piece of diamond:

USD 670 (RM 2762.02).

What ring setting are they providing? 14k? 18k? Nonetheless, either one, I would say the price is pretty fair.

And I am just answering whether it is worth it or not from a pricing perspective, not quality. Personally, I will look for something like this:

The final price for this sort of diamond will probably touch RM 4500 - RM 5000, together with a 18k white gold ring. More expensive, 1 grade lower in colour, but better in terms of cut quality and performance. The sample has faint fluorescence.

Of course, the choice is up to you.

33.5 CA pair with 41.6 PA will most certainly won't work. You will need a shallower crown to work with that PA.

To know whether a piece of diamond has crown angle that works well against each other, use the HCA tool:

Just pump in the numbers, or the certificate number (sometimes work, sometimes no).

IGI cert?

Oh, The Love Diamond from SUEN. They are said to be cut to Hearts & Arrows, and I believe their certificate has the images as well. I would assume that their performance will be better than the typical diamond that you will see in most places. The CA and PA pairing looks okay to me.

Their price won't be cheap as far as I know, but you do get to enjoy the brick-and-mortar store experience.

If you feel comfortable buying online, here are a couple of Hearts & Arrows diamond with proof of performance:

https://black.briangavindiamonds.com/diamon...?a_aid=myengexp (affiliate link). I see that you are aiming for close to 0.5ct diamond. If that is the case, this is a good choice. This piece will cost approximately RM 6470.23. The images aren't up yet but if you are interested, contact their sales consultant and they should be able to expedite your request.

This piece from WhiteFlash is slightly smaller, but it is another good option if you want to save some money:

Solitaire ring setting set starts at RM 1499.00:
https://memoryjewellery.com/category/engagement-ring/ - The downside for Memory Jewellery ring setting is that their white gold uses nickel as the whitening agent instead of palladium, while SUEN ones should be using palladium as far as I know. But then, most people are not sensitive to nickel. If you want customize ring with palladium in the white gold, then look for iDo Jewellery - http://idojewellery.com.

Final price for each respectively: RM 6470.23 + RM 1499.00 = RM 7969.23 || RM 5541.20 + RM 1499.00 = 7040.20.
