Enchanted Cut Score (works for GIA only)
https://enchanteddiamonds.com/cut-score-cal...d=R36-726864931
96.6%

HCA:
4.3

Simplest understanding: The HCA score is way to low. So skip it.

More complex understanding: 35.5 degree is the average crown angle rounded to the nearest 0.5 degree (for GIA). So the real average crown angle could be 35.7 degree, or it could be 35.3 degree. If 35.7 degree, then it is not a diamond that can perform too well.

If that is not enough, I was told by Todd Gray from www.niceice.com that 41 degree crown angle has to be paired with 43.3% pavilion depth. A 43.5% pavilion depth is a no go. There will be light leakage.

Proportions are not that hard to understand, what you are looking for is the "middle"/"center"/"bulls-eye" of those triple excellent. It is the safest bet. To start with, try to look for diamonds between 34 - 35 crown angle that pairs with pavilion angle between 40.6 - 40.9 degree.

Audrey's won't be a bad place to buy, it is tied to huge diamond suppliers. Just that, you can't see the diamond physically before you purchase. You can try to ask them for the photos of the diamond, such as the actual diamond photo, Hearts & Arrows image, IdealScope image. Chances are slim though. I would place my bet on WhiteFlash or Brian Gavin if I want to purchase online. If you are interested in either of them, feel free to let me know as I am affiliated to them.

I know that buying online is not everyone's preference. So I would recommend you to visit Wah Chan also. They got a flagship at Section 14 PJ. I think you will find it worthwhile spending hours there, just like some others here.

Feel free to ask me about other options you bumped into. I will try my best to help.

Good luck!

1. Memory Jewellery @ Sentul.
2. iDo Jewellery @ Bukit Jalil.
3. Eumayco @ Bangsar South.
4. Suen @ Bangsar.
5. Brick and mortar stores, like Wah Chan as well.

You can find most of them on Facebook.

No harm asking if you visit any of them. Some of them may scare you first telling you that buying online has risk and stuff though. Anyway, it is always good to ask and know more then make you own judgement call.
