Again thank you Kathie for the recommendation and as promised here are the correct contact details for SJ

Tel: 02 - 2432446 or 02 - 2411875
125/8 Sawankhalok Road, Dusit, Bangkok

To those reading this message, call the store and they will send a car for you.

(These are the phone numbers on the cards I have as well... were there other phone numbers posted here? Oh, given that I've been recommending this place for many years, it's quite possible that an old thread listed numbers when the dialing prefixes were different...)

Kathie - thanks for making my hurried post clear.
There were other numbers on this site and those are the ones I had written downand so was not able to make contact. Iasked the hotel in Bangkok to look up the correct number for me and SJ sent their driver to pick me up - great place

Can someone tell me if they do repairs? My wedding ring needs re.sizing and some repair to the engraved pattern from the last time I had it re-sized here in Aust. I will have 6 days in Bangkok.

I've had repairs done, as well as some custom new pieces. Very nice work, and very reasonable. They even did some repairs free, but that may have been due to the amount of new stuff I was purchasing!
