Beautiful Layered Art Glass Red and White Vase

This is a beautiful layered art glass vase. The inside layer is bright ruby, cherry, or candy apple red, The outside layer is clear with a white crackled, or textured glass. It is a nice heavy piece and measures 7 inches high and 5.25 inches across. It is in excellent condition, no chips, no cracks, and no scratches that I can see. It looks hand blown to me, but I am not sure. I don't know the age or maker.
