There are many cool Rutiles around, but gram for gram this is one of the finest I have ever seen. The intergrown mostly-terminated! crystals have a superb striated luster and deep red color that takes very little coaxing to glow. The geometry of the bladed crystals creates an architecture that has superb aesthetics. Even better in person, this is an absolute killer. It flashes electric red from so many angles! This is unusually robust for such a reticulated cluster, not jus tskinny needles strung together but real 3-D crystals.
