Rhodochrosite is a manganese carbonate (MnCO3) prized for its rose-red to pink color. It crystallizes in the trigonal system, forming rhombohedral crystals as well as massive, banded, and stalactitic aggregates, with a vitreous luster, a white streak, and perfect rhombohedral cleavage. Its Mohs hardness is 3.5 to 4 and its specific gravity 3.45 to 3.70. Banded rhodochrosite from Argentina is especially well known and serves as that country's national mineral, while superb crystallized specimens come from the Sweet Home Mine in Colorado. Its perfect rhombohedral cleavage and translucent vitreous crystals aid identification, and a Mohs hardness of 3.5 to 4 places it among the softer carbonates.

Rhodochrosite는 아름다운 장미빛~분홍색으로 유명한 탄산망간 광물이다. 아르헨티나산 띠 무늬 로도크로사이트가 특히 유명하며, 아르헨티나의 국가 광물이다. 콜로라도주 Sweet Home 광산에서 뛰어난 결정 표본이 산출된다.
