James Allen is one of them. Their prices are quite good...but since the recent slump in MYR against the USD, I am afraid not any more.

You can try Tailored Jewel. They are a local jeweller who supply diamonds and do customisation as well. The boss punya contact is below:

Ethon Low
012-255 5866
ethonlow.wk@tailoredjewel.com
http://tailoredjewel.com/

Another one is Audrey Diamonds. But this one I have not tried so I can't provide any feedback. Maybe kambingkoh can comment a bit on Audrey's.

Shopping around for a ring too at the moment. My second time after sixteen years. It seems things have definitely moved on in this diamond ring business.

Great thread!

I shop online regularly, and I have had a number of orders go missing during postage. I still can't wrap my head around the idea of ordering a diamond or ring costing several thousand via post!

Haha, I did not buy from them before. But they are quite fast in terms of repsonding to emails. It is a good place to survey for diamond prices, but I am not sure about other areas. One thing I am sure is that they end my emails with "Do you wish to proceed with the sale?". Anyway, that time I was very new to diamonds and I don't know what questions to ask. Maybe they will be able to answer on certain questions regarding the diamond angles and proportions. Anyone interested should try asking.

For jrrsim, if budget is really your main concern. Please get the quotes from the 3 vendors below:
1. Tailored Jewel (was introduced by bb100 too)
2. ZCOVA
3. Eumayco (you will see them alot on facebook advertisement once you searched for rings)

Ask them if they have promotion running. Ask them for a few diamonds' cert number. To determine which one is the best:
http://www.pricescope.com/tools/hca (type in proportions according to cert, not that hard)
http://www.pricescope.com/tools/AGA_NAJA_Cut_Class_Grader (type in the proportions according to cert, not that hard)
https://enchanteddiamonds.com/cut-score-calculator (easiest, just put in cert number)

Good luck and all the best in your diamond hunt!

Usually online stores overseas use Fedex. Along with insurance as well. They will pass to you by hand!

The crown angle is actually too steep at 36 degrees. May affect light return. Hence Datlas class grader returns 2B for it, which means it is at 4 out of 8 (lower is better). Read:

QUOTE
Steep-end of the Ideal Crown Angle

For a fixed table percentage, a steeper crown means that the crown is higher and the crown facets are larger. This means more incident light rays can fall onto the prism-like crowns generating more dispersion so the diamond will have more fire.

The trade-off of having a steeper crown angles is that the lower girdles tend to begin leaking light once you go over a 35-degree crown even if you have a 40.8-degree pavilion. This happens because the lower girdle angles are dependent on the pavilion angle and the lower girdle length and a steeper pavilion causes even steeper lower girdle facets.

Even with a 40.5-degree pavilion and shallow lower girdles, you really do not want the crown angle to be over 35.5 degrees.


Therefore, check with iDo for the IdealScope and ASET as suggested by bb100, they do have them according to what I was told.

Wow, same proportions, other than the depth.


Tab Percent: 1A
Crown Angle: 2B
Crown Height: 1A
Pavilion Depth: 1B
Girdle: 1B
Depth: 1B

Polish: 1A
Symmetry: 1A
TotalGrade: 1B

Girdle and depth grading drop slightly by 1 grade. HCA is same as before @1.9. Fire is excellent because of the steep crown @36 degrees, but at the expense of brilliance (light return).

But then, my advice is still go for the 0.4ct because every 0.1ct is a big jump, and the amount difference (RM 400) does not seem to fill the actual price difference. In other words, 0.4ct is more value for money. 0.34ct is not worth it in this case.

If you buy anything less than 0.4ct from iDo, WhiteFlash can offer you a better deal. They provide free shipping as well as insurance (but the price for shipment and insurance is taxable in Malaysia at 6%, luckily it is not that much). The diamond is also taxable, but then even adding in 6% GST, the price is still cheaper than what is offered to you. Just plug in the numbers into Datlas Cut Grader and HCA, I am sure the score will be better than what iDo offered you for the 0.34ct. Also, I have also included in RM 2000 for the setting when calculating the price.

In fact, another diamond that is sold by BGD is very close to 0.4ct, but you save on the premium for the 0.1ct price jump. They provide you with all the details, and the price is still not bad. Although it is SI1, since this is their signature diamond, it should be fine, then D colour is even 1 grade higher, although not significantly higher. But then, people will notice the overall colour more than clarity because colour is more obvious.
http://www.briangavindiamonds.com/diamonds...#33;prettyPhoto[gallery2]/0/
The downside of BGD is that you may need to pay for the shipping, insurance, and the ring box (as far as I remember). Anyway, I may check with them when I have the time.

So once again, my advice is to go for 0.4ct if possible. If not, buy online elsewhere is cheaper.

Here is the math for a 0.33ct diamond:
I round up to 900 USD. Exhange rate I put it 4.53 so diamond price is RM 4077. Add in GST, total is RM 4321.62. Add in tax for freight and insurance, probably will only cost you something like RM 50 - RM 100. Anyway, I just put high enough til RM 4500. So diamond price is RM 1000 difference. Let iDo do the setting is probably RM 1900 (last heard is this). So I boost up til RM 2000. So total is RM 6500. Complete ring. E color and F color is 1 grade different. So is VS1 and VS2. But you now get a super ideal cut from WhiteFlash, compare to a over-steep 36 degrees. I am not expert, but I know 36 degrees is not that recommended by experts, unless of course when the deal is good, but it is not in this case.

Even worse.

https://enchanteddiamonds.com/cut-score-cal...cate=5233181671
Cut Score: 65.6

Datlas Cut Class Grader:
Tab Percent: 1B
Crown Angle: 3A
Crown Height: 2A
Pavilion Depth: 1A
Girdle: 2B
Depth: 1A
Polish: 1A
Symmetry: 1A
TotalGrade: 2B

So, grade: 4/8

Remember HCA is not everything because they take into account of 17 facets only. Standard round diamond has 57 facets, include culet will have 58 facets. Anyway, we just call it 57 facets.

Also, remember that HCA is not diamond selector tool, it is a diamond rejection tool. Although this diamond passed HCA with 1.1, but then it failed on other tests. Read more about HCA here: http://www.goodoldgold.com/consumers-guide-hca

Checked on the cert indicates that the crown angle is toooooo shallow at 31.5 degrees. More steep = more fire. Usually online research will encourage people too choose a crown angle between +- 34 to +- 35.

Also, at 31.5 degrees, Hearts & Arrows most likely will not be found:
http://www.heartsandarrows.com/hearts-arro...al-cut-dna.aspx

Just don't buy it.

Hello,

Mind sharing how much that diamond cost?

Previously, I was also looking for a ring with a budget similar to yours. I just wanted to share with you the quotation that I got from Tailored Jewel just in case you're interested. Ethan is a nice guy, but I did not purchase from him. I ended up buying a diamond from Wah Chan instead. I might consider getting the wedding band from Tailored Jewel

Crown angle = Tolkowsky’s ideal proportions
Pavilion angle = Close enough to Tolkowsky’s ideal proportions (40.75)

Don't worry about the "fail" part, those are just individual opinions from different websites. Also, don't worry too much about the faint fluorescence. In fact, according to http://beyond4cs.com/grading/fluorescence/...parency-issues/, there is a significantly high chance that it won't cause any issue such as milky appearance. You may ask your seller to check for the appearance and see if it is milky or not, if he/she is able to get the images of the diamond, it is even better. Images will be diamond image, ASET image, idealscope image.

Lastly, among all the stones you show me, I think this is the one I will buy myself personally. Since we are buying without actually looking into the real diamond, then all we can rely is the figures, and it will be best if we can verify our decision with the necessary images.

Hope this helps and good luck. wink.gif

Dude, this is dangerous! There is a term for this: buying blind. If the seller is not able to provide the scope images, I would not even waste time looking into its proportions.

The depth and table percentages, and crown and pavilion angles are only figures. They don't tell you as much as a scope image would.

The stone has faint fluorescence. Fluorescent diamonds usually cost less. Try and nego with the seller on this point. Maybe you can shave a few hundred off the listed price.
