Yes, they would look great. And definitely they would need a big, sturdy surface. The apple would break a shelf over time, so sets in the middle of the dining table.
I agree that the Seguso alabastro sfumato fume' pieces look most like the ones in this thread. Now a big question -- what does fume' mean? I have heard of this type of glass, but have never read the definition. Does it mean the pigment is applied to the surface? The rose color in the apple appears to be only skin... er peel deep.
