A rare greenish mineral of the sorosilicate group, typically found in metamorphic rocks.
Named after a specific location or mineral collector (the 'djalma' part likely references a place or person's name in an indigenous language). Mineralogical naming conventions often use place names or person names, particularly from the regions where minerals are discovered.
Djalmaite is so rare and obscure that even many geologists haven't heard of it—it's a reminder that while we've catalogued thousands of minerals, new ones are still being discovered and named, often with names that preserve indigenous languages or honor the scientists who find them.
