Thanks. I think buying from Zcova is much better value for money.

VVS1 basically is overkill. A feather in VVS1 is nothing to be worried about. If can, I will try to lower the clarity to VS range and up the diamond colour. Personally I like VS1 because it gives me a peace of mind, but usually VS2 will be fine as well. You can ask further details from the jeweler that serves you and see if they can find out where is the inclusion, and whether the inclusion is "dark" in colour, which can be more obvious, compared to transparent inclusions.

The more fluorescence it has, the lower the price of the diamond will be, assuming other factors are constant.

I think it will be best to see what is your budget and using that, you scout for your options. While ZCOVA is a good place to begin, you can also try DeGem Gia diamond website, which is also pretty decent. DeGem website sells typical GIA diamond at a reasonable price and their ring settings are definitely on the cheaper site.

Whether you should skip both diamonds really require more details of how the diamond look like, such as whether it has good arrows or not, and good proportions or not. Excellent cut can consists of good and bad diamonds.

Love & co got some lab growns, but the cert I am not sure whether is IGI or not. SK jewelry, which is their parent company should have some too. You can find these 2 store brands in shopping centers.

The other brand is Gordon Max. You can Google it up.

I think iDo jewelry may also take in some lab grown, you can WhatsApp them and ask.

ZCOVA also carry lab grown, but I am not sure whether they keep some ready stock or not.

Based on the time estimate, I think is possible for them to send out in 3 weeks. DeGem online lets you choose the ring size accordingly as well. Since you visited Poh Kong, I think you can consider visiting DeGem as well to get the correct ring size.

Try and see if there is Diamond & Platinum, they belong to the same group of companies.

The old post is based on WhiteFlash parameters for their ACA diamonds. In reality, different brands will have slightly different parameters. Personally, I don't mind a diamond that go above 62% depth, but not too far apart. Same goes for the table percentage of the diamond.

As for VG vs EX, I will go with EX as that is one of the main requirements for a good diamond. Fluorescence is alright as long as it doesn't affect the overall appearance of the diamond... Internet source says it may have a chance to make a diamond looks milky, but in reality, we have to see case-by-case basis. So if someone tells you that EX is more important compared to fluorescence, I don't think you are being misguided IMO.

Micro pave halo setting to me looks elegant, but the wearer probably need to dress up abit to match it, at least that's what i think. For a wedding ring, it seems suitable because the bridge will most likely dress up nicely in a wedding dress. For day-to-day basis, I prefer non-halo. Halo does make the overall appearance looks bigger.
