South East Asia Wholesale silver jewelry

I’m going to both Bangkok and Hong Kong in September to buy silver
jewelry for my store and attend two tradeshows.

I used to spend quite a bit of time in Asia and had good contacts in
both Bangkok and Bali; however, its been several years since I was
last in Bangkok, and I’m sure things have changed.

Can anyone recommend particular areas of Bangkok where lots of
manufacturers/wholesalers are located? The areas I’m familar with
are (excuse my spelling) Khao San Road, New Road, and Nowlipon
