Conduct the scratch test: Start with a mineral of known hardness and try to scratch the unknown mineral with it.If that mineral leaves a scratch, the hardness of the unknown mineral is less than or equal to the known material. If the known mineral doesn't scratch the one of undetermined hardness, then the unknown material is higher than the known mineral.
