Cassiterite
stock #ALEC-22-183
San Antonio Mine
Loayza Province, La Paz department, Bolivia
5 x 3.4 x 2.2 CM (miniature)
price: $140
pre Tucson 2015 update

One of the oldest and best localities for fine Cassiterites in the Americas is the La Paz area of Bolivia. This specimen has well formed and lustrous crystals that under strong lighting show some translucence. The "naked eye" color is shiny black but the "under strong lighting" color is a deep honey orange hue. Some tiny edge chipping exists but most crystals are pristine and the quality for the price is a very good value.
Cassiterite (twinned) on Arseopyrite
stock #7-BOLI-131
Viloca Mine (Araca Mine)
Loayza Province, La Paz department, Bolivia
10.8 X 7.4 CM (cabinet)
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.
