Traveling with gemstones international

Hello all,
my name is Thomas and I am starting a journey to southeast Asia , into India and then through over to Europe.

I’m planning on taking multiple classes along the way gem faceting and jewelry making as well stop at GIA in Bangkok.

I’m very excited that I have found this community here online!!!

I have a collection of gemstones (tourmalines, garnets, aquamarine, topaz, etc.) (no sapphires, emeralds, or rubies, no diamonds either) that I want to bring with me.
does anybody know with the customs and duties could be like potentially on bringing these gemstones over with me on my carry-on?

Traveling with some electronic jewelry equipment as well and hoping to get some clear insight (or clearer insight I should say) Into what I should prepare for, watch out for or just flat leave at home and not travel with.

Any advice and or experiences would be greatly appreciated I plan on leaving the United States in late December and traveling for one year.

Thanks for any help!!

Hide your gems good. And dont show them. That would be my opinion.

well it is not advised to travel with to many peaces as they maye be taken from you as amounts of gems are prohibited but for more info rather contact me on whatsaap on +27712817588 jarred gemoligest
