'Pereña' is a mythical name in Spanish mineralogy because, when pegmatites were being handed out, Spain must have missed the meeting, because it has very few, and for this reason, although tiny (compared to those of other countries), the Pereña de la Ribera pegmatite is quite famous for its heliodor Beryls, smoky Quartz and many other species. So I was very happy to be able to get this piece from Manolo Tomé. It has extra-flat Quartz and an intense smoky color, almost black, with good transparency and luster.
