The mineral that has no cleavage and cannot be scratched with a steel file is typically quartz. Quartz is known for its hardness, ranking 7 on the Mohs scale, which means it can only be scratched by harder materials. Its lack of cleavage results in conchoidal fractures, giving it a distinctive break pattern. Other minerals with similar characteristics may include certain varieties of garnet or tourmaline, but quartz is the most commonly referenced.
