An aesthetic specimen of andradite, a variety of melanite, formed by numerous, well-defined, idiomorphic crystals, with the dodecahedron faces truncated by the trapezohedron ones. They are lustrous and shows greenish reflections and transparencies when light hits them. They are on both sides of the sample, with numerous elongated, prismatic crystals of green pargasite, one of the first historically described amphiboles.
