I just rewatched the scene. Honestly, it looks to me like the sort of ornament one might find in a dollar store. It looks more like glittery plastic than anything else, but I might be able to buy that it was space stone that was primarily mica. (Mica, is, after all, both glittery and light. I don't know how common it is in outer space but, all he would need would be one piece.) As I said, I could buy that it was mica; but then again, I could also buy (for the purposes of enjoying the show) that a man can fly... (It doesn't look terribly like mica, but that's the best I can come up with.)
Virginia, I could sort of see it being frosted glass, except that I would think that the tiny tree would have bent under the weight of that much frosted glass.
I still think it looks like a plastic gewgaw one would buy at a Dollar Store; maybe there's such a store on the space station, and he bought it there? ;-)
Joy,
