Antimony is a rare mineral in hydrothermal antimony and nickel-cobalt-silver veins. Frequently containing arsenic, it is found in its native state, in granular or lamellar masses, rarely botryoidal or hilly, sometimes imposing : 135 kg at Erskin Creek (California). Its name comes either from the Arabic al uthmund, or from the Latin antimonium applied to the stibine by Constantinius Africanus (around 1050). The crystals are very rare, pseudocubic, or thick tabular on {0001}, frequently rounded, not exceeding 15 mm. Antimony has a metallic luster and a pewter-white color taking on a yellowish reflection by weathering. On the surface, antimony easily deteriorates into valentinite and other white antimony oxides. Its rarity prevents it from significant industrial use; however, it may have been a very occasional antimony ore.

Twins on {01-14} and commonly forms fourlings, sixlings and polysynthetic twins.
