Not sure about the membership thingy, but may I know is it wedding band or diamond ring?

Perhaps you can list down the price here and see if after 25% discount or more is worth the price. 

It seems that you are looking for wedding band then? The price seems okay for me as it is quite standard. Ask the salesperson how heavy is the 18k white gold in terms of grams, what is the average colour and clarity of the side stones, how many individual stones are there altogether, and then you are good to go. Try to push for an additional 5% discount if can.

They don't ship to Malaysia. And if they do, yes, you will kena GST.

Not too sure. Which store quoted you? If it is not brick-and-mortar stores, then the price may probably be okay IMO. Btw, is it plat 95? Also, is it for proposal ring or just wedding bands? If wedding bands, then check out Tailored Jewel, iDo Jewellery, ZCOVA, Eumayco Jewellery, Memory Jewellery on Facebook. If for proposal ring, then you can skip Tailored Jewel, and check out with the rest.

Hmm, two channels? Paved with side diamonds? Or how ah? Can take a look at the design? Also, do you have the wedding band width?

Just noticed that I did not include a cheaper alternative in my blog. So I went to Zoara and look for one:

This one scores 100% on Enchanted Cut Score Calculator and has an HCA score of 1.3. The arrows are well-aligned as well. The proportions will give you a pretty balanced of brilliance and fire.

Now, this is my own marketing statement  : You don't see 34.5 crown angle and 40.8 pavilion angle daily. This combination of crown angle and pavilion angle is closed to Tolkowsky ideal cut. Personally, I prefer steeper crowns for more fire.

Although the lower girdle facets (LGF) of 80% will tend to display smaller size flashes compared to bolder flashes, but it should be pretty acceptable, especially at this price. If I compared to WhiteFlash's ACA standard, they would accept lower girdle length of 80% into their ACA list.

On a side note, GIA tends to round the LGF to the nearest 5%, therefore, the looks of it tell me that this LGF is probably between 78% - 80%. Just some educated guess. The easiest way is to compared with another diamond with the same star length and LGF: http://www.zoara.com/diamonds/p_round_exce...id=myengringexp (affiliate link). This diamond also has LGF of 80% and star length of 50%, but its arrows are somewhat slightly thinner than the first diamond I recommended. FYI, the higher the LGF, the thinner the arrows. Therefore, this is how I arrived at the conclusion that the LGF of the first diamond is between 78% - 80%, on top of my experience of looking at various ACA diamonds before hand (although with various star lengths).

Another thing to note that this diamond has some light obsctruction at 4 o'clock, 6 o'clock, and 8 o'clock positions, with the one at 4 o'clock being the most obvious. But nonetheless, this is after-all not a super-ideal diamond, but more towards a decent performer for its price. Therefore, it is a good value buy to me.

At USD 846 + USD 30 (shipment handling fee) = USD 876, using MoneyMatch (https://transfer.moneymatch.co) to make the transfer, the price is RM is RM 3737.20. Add 6% GST, the price is RM 3961.43. Add some misc. charges for GST on freight and insurance, the final price will be approximately RM 4000.00. Comparable diamonds at WhiteFlash or Brian Gavin will probably hit 4 digits USD, that's why this is a value buy with not too bad performance.

Memory Jewellery offers pretty reasonable priced ring settings and a simple solitaire using your own custom design probably cost between RM 1000 - RM 1500. Ready-made designs can be cheaper. Check with them on Facebook for latest price. As usual, if you are buying 18k white gold engagement ring, request for palladium and see if they can cater for it. Palladium rarely cause sensitive to skin, like nickel, but nickel is actually relatively safe for most people. Anyway, palladium is a better choice. Then, request for a wider ring shank (the default I think is 1mm) and extra rhodium plating to make the ring setting longer lasting.

Depends who is the jeweler. If you feel dodgy then you can opt for the later option. Eventually you will still need to pass it to them to set anyway, so I think both options make a great difference.

I am not sure how hard to fake it, but usually it wont worth the time and effort to change a diamond. And it is not worth to sacrifice the reputation if it is already a famous one.
