Chinese Black Stone & Resin? Necklace

I suspect the stone is dyed but could be wrong. The monkeys, some type of resin?
Thanks

 

The monkey LOOK like resin, no problem, they're cute as a button!

The carved dark stones look like some sort of soap stone - do they click on your teeth like stone?

The orangish flat rounded stone beneath the monkey's bottoms looks like it might be agate, not sure, cannot see it well enough.

The monkeys appear to be sitting upon lacquer like the type chopsticks are made from and could even be a piece of a chopstick.

Those are my best guesses.

 

Thanks for the suggestions.
Here are mine after a bit of research.
Black stone, possibly obsidian
The see/hear/speak no evil, most likely boxwood( never heard of it before)
The flat stone, agate.
The stick, not sure
There is also a painted porcelain bead with some characters on it.
So, it seems like someone assembled cheap and recent "aliexpress" pieces.
