Vietnamese Opium artifacts

Hi lovely members

I've just purchased on a whim, 3 Opium pipes, detailed as possibly from Laos, Vietnam.

Firstly, I'm wondering if these items originate from Vietnam and if so, do they look like they're from the Hill tribe?

Secondly, I'd love to know an approximate valuation, hoping that I got a good deal )

Thanks in advance ☺️

 

The green one has a Chinese pseudo Qianlong mark on it, so is probably mid 20th century (and made in China). The cloisonne pipe is Chinese 2nd half of the 20th century.

 

u got a good deal.

 

Thanks, but not knowing there worth, have I ? I found a long pipe on Catawiki (but it didn't have the Amber mouthpiece) sold for €100, however, unsure if it was an older piece.

 

The bone pipe also has writing on the back, but couldn't add any more photo's. I'll try to add again.
