Custom Jewellery Recommendation (Ho Chi Minh City)

Hi all,

It's our 5 year anniversary and I'm looking to have some jewellery made for my wife, however I can't seem to find any recommended custom jewellery places in Saigon which has led me here to ask you all for your help. I know there are many places to buy pre-made jewellery, that's pretty much where my current knowledge ends.

If anyone has used a jeweller in Saigon for custom jewellery, or can give me a lead, it would be most appreciated.
