Few Chinese Stone Carvings

Any comments on type of stone, age etc?
Thanks

 

I like the orange one... assume it's a snuff bottle? Don't have any idea about age.

 

The orange and red are coral for sure. The green one could be serpentine. Not sure of the dark one.

 

Thanks, I thought coral too. The orange is a snuff bottle, not sure what is the red one, maybe just a pendant?
The dark one is some kind of Jade I think. Probably not the real deal. It does not get cold fast after being warmed. But it's 100 degrees here.

 

You asked about age-the only one with real clues is the orange one, which I think is fairly recent due to what appear to be plastic, rubber, etc. parts of the stopper.

 

and dyeing of coral is a recent deal

 

I agree! The red piece is definitely died coral. I had a bunch of Buddhas made from the same material; don't leave them soaking in water or they will end up anywhere from white to pink.
