This cabinet sized piece features a dense coating of black, lustrous, sharp Cassiterite crystals on a rust-colored matrix from the famous Viloco Mine in Bolivia. The Cassiterite crystals are large, very sharp and mirror-like and contrast amazingly with the matrix. A very aesthetic piece with great color, luster, contrast and crystal formation. In excellent condition.
