• The minerals coming in the 7 scale are Quartz, Citrine, Agate, and Amethyst, and the mineral coming in the 5 scale is apatite.
• Thus, when one rubs the mineral with 7 hardness with a mineral with 5 hardness, than the mineral with 5 hardness will easily get scratched as it is less harder to the mineral in the 7 scale.
