Axinite is a group of minerals that belong to the sorosilicate class. They have a complex chemical composition that includes calcium, iron, magnesium, manganese, titanium and boron. Axinite crystals are typically brown, violet or blue in color and have a vitreous luster. They form in metamorphic rocks that have undergone high-pressure and low-temperature conditions. Axinite is valued by collectors for its distinctive wedge-shaped crystals and pleochroic colors.
