Zaratite is a rare mineral that is typically found in copper mines. Its chemical formula is Ni3CO3(OH)4 and it is prized by collectors for its deep green color and unique crystal structure. Some synonyms for zaratite include green nickel ore, nickel carbonate hydroxide, and nickelium. Zaratite is often mistaken for malachite, another green mineral that is commonly found in copper deposits. However, zaratite has a brighter and more intense color than malachite, as well as a less earthy texture. Despite its rarity, zaratite is highly sought after by mineral collectors and enthusiasts.
