Indicolite, a type of tourmaline, belongs to the complex borosilicate mineral family. Its name, derived from the Latin “indicum” meaning “blue,” reflects its vibrant blue hue.
This mineral, with a history spanning thousands of years, was initially uncovered in Sri Lanka and later discovered in various global locations.
Predominantly found in coarse-grained igneous rocks known as pegmatite veins, indicolite tourmaline is commonly associated with minerals like quartz, feldspar, and mica.
Notable deposits are located in countries such as Brazil, Nigeria, Mozambique, Afghanistan, Madagascar, and the United States.
