A very 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 disposed in a very aerial way on a matrix formed by numerous elongated, prismatic crystals of green pargasite, one of the first historically described amphiboles.
