Firstly, it would be best to comment here instead of starting a new thread:

Now, G colour will look pretty white. The differences are not that far off. You may see some subtle differences when compared side-by-side. Also, the colour of the diamond will be more noticeable on the diamond body, not on the top-down view of the diamond, whereby it is the usual way how most people view diamonds. Next, strong light return will certainly help the diamond to look brighter and hence whiter.

Now, I wouldn't recommend you to go for Very Good cut. This is because Excellent cut diamonds are too plenty in the market. There is really no point to go for Very Good unless your budget is very very tight and want a bigger stone.

You did not state your budget and the price of both stones so I can't really suggest any for you. For GIA diamonds, and your minimum requirement is just Triple Excellent, I can find plenty in Zoara -  https://www.zoara.com?a_aid=myengringexp (affiliate link), a company which I am affiliate with. They sell Triple Excellent at pretty reasonable price, so let me know your budget and I see what I can do.

If you don't mind smaller carat size like 0.25ct, I can probably suggest Black by Brian Gavin - http://black.briangavindiamonds.com?a_aid=myengexp (affiliate link) for you. They are selling super ideal diamonds that are top of the line diamonds. Superb quality.

Let me know or PM me.

Good luck.

Do you have the cert numbers for reference?

No problem. But if you are going back to that shop. Try ask for it. The proportions and the cut quality will affect the price.

This one looks promising. 0.23ct E IF. Excellent colour and excellent clarity. This is probably the one I will buy based on what I can source. Don't have any performance images but should be above average. Price is USD 533 + USD 33 for shipping handling. Total is RM 566. Now should be tax-free if ship in to Malaysia.

If you want better cut quality or better proportions, you will have to cut down on either colour or clarity. But if you are concerned about colour and clarity and does not want to sacrifice too much on cut, then this is one of the better options there is to offer right now.

Transferring via MoneyMatch is 4.0032, making the price in ringgit to be RM 2265.81. Getting a basic solitaire ring setting from Memory Jewellery will be between RM 750 to RM 1000. They are not that thick but they can help with your budget. Anyway, I believe Wah Chan's rings are not that thick as well. My prediction is RM 3300 should be the final price. It is 10% up from your original budget so I am not sure whether this fits your bill or not.

Btw, Memory Jewellery is offering 0.3ct for RM 3500 including setting. You may consult them on Facebook as well. Not sure about the quality though.

My personal advice is to go for warmer colours and focus on cut quality and proportions. This can cut down the cost. While doing so, you can also consider diamonds with blue fluorescence to cut down additional cost as well, at the same time, it is said that blue fluorescence can make warmer coloured diamonds look whiter.

Tbh, I will avoid. 41.4 & 41.8 crown angle respectively... there will be light leakage like no tomorrow.
[attachmentid=9844243]
[attachmentid=9844245]

The crown angle and the pavilion angle works in inverse against each other. 41.4 pavilion should pair with probably something like 32.5 or something like that. Pairing with crown angle of 34.5 is 99% sure fail. However, pairing with shallow crown like 32.5 can kill off the diamond's fire, so one way or the other, I won't recommend it. For the other Very Good cut. The VG says it all. And the pairing of 35.5 crown with 41.8 pavilion angle? No good.

The price? The not-too-good proportions justify it. It seems fair enough considering the quality but I won't spend money on something that I know won't be good even if it is cheap enough.

As for the 0.3ct, my advice is to skip it.

Would rather go for lower colour or clarity rather than bad cut.

It is not that hard to check. Just look for crown angle between 34 to 35 and pavilion angle between 40.6 go 40.9.

Comparing 4Cs alone, I would probably go with the 0.22ct D VS1. At least on paper, it looks nicer.

Nonetheless, since you can see both stones, I think you can trust your own eyes.

Again, I won't buy any of these. To me, it is really not my type of stones. Why don't you consider warmer colours?

Well, there you have it. Trust your eyes. Lol. Slightly warmer means going down the colour chart lor. D E F G H I J K ... and so on.

RM 2400 for 0.22ct 3EX and 18k white gold setting (is 18k gold right?), seems fair enough for me. Besides, you can stick to your budget with some extra left.

Practical advice is as long as you and your gf is fine with it, then it is not a problem to you anymore. Money can be better spent/invest elsewhere. It is afterall, just a tiny part of a long journey. You can also probably nego a good price for wedding bands as well if you are a returning customer.

Glad to help.

Wow. That's fast.

Well I will just be straight. It is abit deep to my liking. 62.8% is pretty deep, so the light return is probably not as good. The pairing between crown angle and pavilion angle is acceptable though. That being said, since this is a D color diamond, it will definitely look whitish enough. The fire of the diamond should be pretty good in pin fire environment, like candle light environment, but may be dull off in office light environment. But again, I believe the whitish D color may help it to look better (my guess).

Most importantly, you saw it and you like it. I think that's what matters at the end of the day.

May I know how much did it cost you?

Did it look any better than the earlier 0.22ct?

The price is not bad. It is overall cheaper than Zoara as well. Probably by around RM 300 based on estimation. And it fits your bill! So yea, it is probably worth it I would say.
