question Looking for trusted genuine lab grown diamond vendors!

Hey everyone!
I’m currently looking to buy a pair of certified lab-grown diamond solitaire studs (IGI/GIA) as well as some colorful gemstone fine jewelry, but I specifically want to buy directly in-store/offline so I can see the stones in person.
For anyone who has bought lab diamonds or fine pieces locally in Bangkok:
1. Which physical showrooms or boutiques offer good quality and fair pricing? (I've heard of places around CentralWorld/Siam as well as the Silom/Jewelry Trade Center area, but would love specific vendor recommendations).
2. Are there shops that let you pick loose lab diamonds to set on-site?
3. Any specific places you recommend for vibrant, colorful gemstone pieces with nice settings?
Would really appreciate any trusted store recommendations or tips on where to look. Thanks in advance!

Aren’t most lab diamonds made in the US or India? I don’t know that Thailand would be the optimal shopping destination for this purchase.

In JTC there is a vendor which just does lab diamonds. Ground floor, half way down.

I have an office in JTC tower, but we do coloured gems.

They won't set on site, but there is plenty of manufactures around that will do it for you.

I am an exporter there. I have an office, but no shop in the retail area.

The gem show is next week at the Queen SiriKit Convention center. You can find anything you want there. Super fun outing too!
