Othoclase, apatite, fluorite, calcite, gypsum, and talc.
Topaz is a common mineral with a hardness of 8 on the Moh's hardness scale. This means it can scratch glass and cannot be scratched with a knife blade or masonry (steel) nail.
Quartz is harder than apatite, quartz being a 7 on the Mohs mineral hardness scale and apatite being a 5.
A mineral's resistance to being scratched is known as it's hardness. You can determine hardness by scratching it with another material whose hardness is already known. If it can be scratched, then the hardness is lower. If the unknown leaves a scratch on the known material, then its hardness is higher.
On the Mohs scale, rose quartz has a hardness of 7.0. Rose quartz is a mineral found in different parts of the world, including Madagascar and India. The Mohs scale is used to measure a minerals' hardness or scratch resistance.
The hardness of quartz on the Mohs scale is seven and can scratch glass.

No. According to Mohs Hardness Scale, Quartz has a hardness of 7 while copper has a hardness of about 3. The higher number indicates a greater hardness.
Its ability to be scratched. That is also determined on mohs hardness scale
A mineral with a hardness of 6 on the Mohs scale can be scratched by anything harder than a 6, such as minerals with a hardness of 7 or higher. It will not be scratched by minerals with a hardness of 5 or lower.
Quartz is harder than apatite, quartz being a 7 on the Mohs mineral hardness scale and apatite being a 5.
Hardness is the measure of how easily a mineral can be scratched.

Kaolinite has a hardness of approximately 2-2.5 on the Mohs Scale. This means it is relatively soft and can be easily scratched by harder minerals.
On the Mohs scale, rose quartz has a hardness of 7.0. Rose quartz is a mineral found in different parts of the world, including Madagascar and India. The Mohs scale is used to measure a minerals' hardness or scratch resistance.
According to the Mohs hardness scale, Quartz is assigned with the hardness 7.
Somewhere between 3 and 5 on the Mohs scale of relative mineral hardness...
