Periclase
1 in the gallery
Periclase is a primary mineral species consisting of magnesium oxide. It typically forms colorless to pale stones or crystals with a vitreous to subhedral luster, often occurring in compact masses or prismatic habits. For collectors, well-formed crystals and associations with high-temperature metamorphic environments are of interest, and the mineral is known from classic localities that expose magnesium-rich assemblages. In Austria, notable crystals and fragment materials are among the specimens that attract attention for their clarity and crystalline form.

About Periclase
Collectors prize periclase for its historical context within mantle-derived mineral assemblages and its relationship to other magnesium minerals. While it is not always abundant in standard rock collections, distinctive crystal faces and lustrous surfaces can make individual pieces stand out, especially when accompanied by complementary minerals that illuminate its geological setting. The mineral’s simple composition and reflective finish contribute to its appeal as a compact, informative display piece that illustrates high-temperature mineralogy.
