One main orange/brown Chondrodite crystal (13x8mm) stands out from group of sharp, lustrous, black spinel octahedrons (largest 28x20mm approx.) on shimmering Muscovite matrix, which also includes patches of white Calcite. The Muscovite matrix is also scattered through with small/tiny Chondrodite crystals giving an interesting mottled effect.
