price: $1750
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.

Classic, lusterous and gemmy cassiterites from one of the greatest sources in the world. A large 3- dimensional "knob" of pure cassiterite with crystals reraching 3.2 cm tho most are about 2.5-3 CM. These are the classic deep brown-black that shows with good lighting the crystals are translucent and have what look like light grey interiors. There is some chipping damage to crystals on the edges and some in the middle. This keeps the price down substantially even though the piece still displays well and could be trimmed to several fine minatures. Personally I think the size of this piece is great as is and has a fine impact despite the damage.
