What is larouchite?

There is limited information available on larouchite, as it is a relatively rare mineral. It is a copper hydroxide mineral that was first discovered in California in the United States. Larouchite is most commonly found in copper deposits and is associated with other minerals such as chrysocolla, brochantite, and malachite. It has a bright green color and a vitreous to earthy luster. The exact chemical formula for larouchite is Cu3(OH)2(CO3)2, and it has a relatively low hardness of 3.5-4 on the Mohs scale. Despite its rarity, larouchite is not of significant economic importance and is primarily of interest to mineral collectors and researchers.
