The specimen is solid Cassiterite with several pseudo-octahedral dark brown crystals to 8mm. Cassiterite is the main ore of tin and contains up to 79% tin. Historically tin was used in tinplates for tin cans and in bronze, which contained about 9% tin. Modern uses of tin include electroplating steel, bronze wire and cable, bearings and bushings, gears, and screws since it is resistant to corrosion. It is non-toxic and thus used in food-processing equipment.
Llallagua is an important producer of tin ore, with moderate temperature sulfide veins containing Bi-Pb-Ag sulfide.

A very nice specimen from an old stone quarry which is long gone by reclamation. The Franckeite on this piece is very reflective, silvery, foliated with striations and occurs on two spots as crystals to 5mm. On one side there are unknown silvery grains to 0.25mm. It is an old Minerals Unlimited piece.
