A very beautiful and unusually symmetrical example of this extremely fragile material from Brazil.  These are by no means hard to obtain, but I rarely see one symmetrical or undamaged enough to temp me into buying it.  This one had an excellent star-like appearance, with the golden rutile needles growing epitaxially on a group of hematite crystals.   Setting this piece apart even further, the hematite crystals are even terminated on the bottom.
