Andorite crystals (Top!) from the Itos Mine, Ouro, Bolivia – miniature specimen as unique piece
Brilliant silvery-metallic Andorite crystals are prominently displayed on this specimen in excellent form. The crystal faces are clearly visible, showing prismatic striations and a distinctive metallic luster typical of this rare sulfosalt mineral. The piece originates from the Itos Mine near Ouro, one of Bolivia’s classic localities for high-quality andorite specimens.
Andorite is a complex silver-antimony sulfosalt and ranks among the rarer ore minerals of this element combination. Due to its attractive crystal form and rarity, it is highly sought after by collectors of systematic and sulfosalt-rich collections.
Geology & Origin:
The Itos Mine is located in one of South America’s most important polymetallic mining districts. Andorite forms in hydrothermal veins alongside tin and silver ores, commonly associated with cassiterite, boulangerite, and sphalerite. Specimens of this quality are uncommon and highlight the geochemical complexity of this renowned locality.
