EFM88AN7: A novelty in Tucson Virtual 2021. Unique fan growths, with three generations, the first being a larger crystal with a slightly smoky color visible on the back of the sample, a second, with crystals of good size and intense color, and a last phase, with smaller crystals, very sharp, translucent, with a very bright luster and an intense and uniform color. It should be noted that the color is not due to inclusions of iron oxides but is the intrinsic color of the quartz. Different from what has been seen so far from this locality.
