36 degrees is actually too steep. It will have excellent fire but will have lesser brilliance. So, it will probably look good in candle light situation, but probably not that good under normal lighting condition. However, the price is actually okay. Anyway need to look at the images, especially idealscope to determine light performance. Btw, can you check with him does his ring contain palladium? or nickel?

For the one you have chosen, faint flourescence may actually cost lesser, but for the price he giving you, I think is still all right.

Diamond 1 looks good. There may be some light leakage though. Don't prefer 36 degrees crown angle, becaue over-steep. Try to take a look under normal light if they have the physical stone.
Diamond 2 arrow shaft misaligned, refer to 6 o'clock position. Don't prefer 36 degrees crown angle, because over-steep. Try to take a look under normal light if they have the physical stone.
Diamond 3 looks good. There may be some light leakage though. 35.5 degrees crown angle is also quite steep already. Try to take a look under normal light if they have the physical stone.

Palladium does not cause allergy, while nickel may cause allergy (but not all people is allergic to it). 18k white gold is made out of 75% pure gold and 25% other materials. Palladium is one of the other materials.

I have updated my blog with some selection: http://myengagementringexperience.blogspot...1-feb-2017.html. Take a look at the diamond image, and take a look back at those provided by Tailored Jewel. Check the idealscope as well. What is the intensity of redness? Lastly, does Tailored Jewel able to provide H&A image?

No problem. But remember that buying a loose stone will take you more time because you need to go find a jeweller to craft your ring setting. I got a few on my list that I know that will do custom ring setting:
1. iDo Jewellery (Bukit Jalil)
2. Memory Jewellery (Pusat Perdagangan D6)
3. Jewellerist (Publika)
4. Suen (Bangsar, formally known as Carat Club)
5. Eumayco (Damansara Perdana)
6. Degem (any branch I guess)
7. Tomei (any branch I guess)
8. Poh Kong (any branch I guess)

Personally, I would prefer non-retail chain jewellers as the service is more personalized.

It is good to see a rise in non-mainstream jewellers in Malaysia they start to move things more towards online. But sadly speaking, as far as Malaysia is concerned, there is more catching up to play. If not mistaken, WhiteFlash started their online business back in 2006 and probably include all the images that time, if that is true, then our local jewellers are probably 10 years behind. I believe that local jewellers do not stock-up a lot of diamonds in their inventory due to capital. They will most likely check with their wholesale supplier and get back to you on your options. The good thing is, they can run this business online and save cost on renting and staffing, and therefore, they are able to provide diamonds at a cheaper price. My opinion is, some of the diamond prices are fair, but if you want all the images, then you probably have to wait for them to catch-up, which I believe one day, some of them may succeed.

If they do stock-up, then they should be able to provide the necessary images - it is really not that expensive to get a basic professional kit: https://ideal-scope.com/product/professiona...al-light-loupe/. Take a look at this explanation on how they capture the photos: http://www.whiteflash.com/whiteflash-diamond-imaging. Of course, I believe WhiteFlash uses more sophisticated equipment and not the basic professional kit, but you get the gist of it.

If you prefer offline purchase and want all those diamond performance explanation service in a brick-and-mortar store, go to Singapore's Jann Paul if you are around there.

I know iDo Jewellery and Suen at Bangsar got. There is also another one called MC Square Studio at Tmn Tun that would probably cost around RM 2100 for your size. 1500 is abit hard to get, probably may start from 1600. Anyway, I will recommend iDo Jewellery first. Try to find out the size of your spouse first if can. If you do it in one shot, the workmanship will be better.

As for others, I am not sure. You may need to check. There is another one that  jacky91 also introduced here. You may check it out also.

Personally, I would go for Memory Jewellery first and see what they offer. Reason being their price seem pretty decent. I don't think palladium is worth an additional RM 850 - RM 1250. The only reason I will get palladium is if my partner is allergic to nickel.

Hope this helps.

Your design 1 is what I ordered from local maker would be getting the ring within this 2 days will upload the picture here once i got it hehe

I like design 3 personally. Usually not much difference in design for any diamonds around 0.4 to 0.46. Advice is to make sure the diamond can sit on a base and does not rely solely on the prongs to grab it. It can make the diamond more secure. Design 3 seems to be doing the job well. Since you mentioned that your gf has tiny fingers, my imagination tells me that design 1 may work well on her too. Do you know her ring size yet btw?

Nowadays many guys did that ehh? One of my friends actually "proposed" to his bride during the Chinese traditional ceremony itself.
