A very fine, esthetic and pristine example with very well formed twinned prismatic crystal. These are well positioned and free standing with excellent luster. Individual prism reach 2CM and the matrix is well crystallized arsenopyrite for a nice contrast. Nearly all Viloco Cassiterite comes out damaged, this large piece is a rarity as there is only very minor chipping at a a few edges that are not obvious, it is virtually pristine. Displays well from many angles.
