The stone doesn't look like a stone to me.
I'd say it's a faceted piece of art glass, could be French...
Amber would have been a good bet except the perfect looking swirl design in it.
Amber has swirls, but that's usually butter amber and this looks transparent
Hard to say what the metal is, but if it were gold, either rose gold or yellow, there would be no signs of what appears darker in areas and to be plating on the back side that is wearing off (higher shiny spots on some parts).
But it's hard for me to see it very well...so, I could be way off
Regardless, it's a nice old pretty piece.
Remember, gold comes out of the ground the same way it goes in, always stays purdy!
Edited so as not to have to post again
I hope you don't mind, but I took the pics into Photoshop and it appears that the glass piece is purple with a goldish color swirl in it, much like one would find in an old marble
