I think that Wandering Jew and Moses-in-the-Cradle could be one in the same; I have one of these and, while it appears glossy like in the picture, it has a dense coat of very fine, short hairs. I've seen ones with much more prominent fuzz, but they have otherwise identical features to the glossy ones. If they aren't the same species, they're at least the same genus. They also vary widely in color from purple to green depending on light conditions; there's a fuzzy one at my school that looks a lot like this one in terms of color, but the side that faces a big window is purple on both the tops and undersides of the leaves. Try putting it outside in the summer for really attractive, compact growth.
