Quartz (variety prase).
EA72AE6: Quartz (variety prase)
Very well defined spear-shaped crystals that are dipyramidal, with absent prismatic faces. They are bright with an intense green color due to inclusions, probably Actinolite and/or Hedenbergite. On the sample there is Quartz with a very different shape, probably a first growth phase, a coating or a substitution of Calcite crystals which have disappeared. The Quartz has formed parallel polycrystalline growths with flattened, almost laminar forms filling and following the empty spaces left by the earlier Calcite.
