Amethyst is also found in igneous, and certain metamorphic rocks, as those contain enough radioactive trace elements for a sufficient irradiation of the crystals. Amethyst from sedimentary rocks is very rare, and the crystals are usually very pale in color.As the ubiquitous iron is built into the crystal lattice, amethyst is sometimes found in ore deposits. However, to be built into the quartz crystal lattice, the iron needs to be present as Fe, and not as Fe.methyst from a druse with goethite, FeOOH, inclusions, Rio Grande do Sul. As mentioned earlier, inclusions of iron minerals can frequently be found in amethyst. The crystals have well developed prism faces, which is not common on amethyst from volcanic druses, and show a patchy distribution of color.
