Flowers and Butterfly Jade Snuff Bottle

I am not sure what to call the color of this jade, maybe russet brown and olive green? But I think it's lovely.
I also "think" this one is jadeite whereas my other jade snuff bottles are nephrite.
On the front the carving is of flowers and a butterfly.
The back is not carved to show the natural color of the stone.
It is well hollowed.
