I brought mine at Audrey as well. their diamond was cheaper but not so sure bout ring setting.
But I did a customize ring setting with them. I was really happy with the outcome but it cost alot for ring setting.
Stone cost me 3k and the ring setting also 3k.
Anyhow i think is worth it as my wife have a unique ring.

I brought my ring like 2 years back.. When ringgit is still strong.
Need to search back for my design..
But i did copy and get the idea from white flash as well. The setting for Audrey is made in hong kong.
This is what they told me. Dunno kena con or not.
