Axinite (Mg) or magnesioaxinites are rare - and even rarer when the terminal faces are intact. They belong to the group of silicates and are grouped together with iron and manganese axinites in the axinite group. Magnesioaxinite crystallizes in the triclinic crystal system and is very hard (Mohs scale: 6.5). The crystals show dichroism in polarized light and pieces containing chromium in particular glow orange-red under long-wave UV light. The different colors and the beautifully structured, shiny crystal surfaces make magnesioaxinite an attractive collector's item.
