Bangkok in December: trusted shops for ready-made gem jewelry and lab-grown stones?
Hi! I'll be in Bangkok for a week in December and want ready-made jewelry only, no custom work: gem-set rings, pendants, bead strands and bracelets.
I'm looking at natural yellow sapphire, ruby, pearl, red coral, or citrine, garnet, carnelian and rainbow moonstone, plus lab-created yellow sapphire and ruby.
I'm planning to browse JTC, Gem Tower/Mahesak Road, Charoen Krung, MBK and Chatuchak Weekend Market.
Which shops or floors do you trust, and which would you avoid? For Chatuchak, which sections are best for gems and jewelry?
What are realistic prices for good natural vs lab-created yellow sapphire and ruby, and is quick resizing doable?
Quality and value matter most, and I'd like to carry pieces home. Recent experiences especially welcome. Thanks!
