JFD92AO1: I do feel a little love for the siderites of Panasqueira. With much less fame than other mineral species from this mine, its variety of forms and its frequent association with other species always attracted me. This specimen well represents what I want to say - The crystal is sharp, its color is pleasant and it shows in its center a kind of growth phantom of trigonal symmetry. In addition, it is associated with Muscovite and Arsenopyrite, both of good quality.
