Vintage Dark Blue Glass(?) Perfume Bottle with Atomizer 

I'm not 100% on the material this is made of, it has a different 'feel' to it than glass but I have no idea what it could be.

In used condition, the ball shows wear and has staining, the metal cap is tarnished, and the bottle has some minor flaws. Please view all pictures and zoom in for the full visual description.

Measures approximately 3.25" tall
