Diamond is the hardest mineral and can only be scratched by another diamond.
Yes, magnetite is harder than a fingernail and cannot be easily scratched with it. Magnetite has a Mohs hardness of 6, while a fingernail typically has a hardness of around 2.5.
No, calcite is harder than a penny and cannot be scratched by it. Calcite has a Mohs hardness of 3, while a penny typically has a hardness of around 3.5 on the Mohs scale.
im not sure someone give a reasonable respectable answer
The scratch test can help distinguish gypsum from quartz. Gypsum is a soft mineral, so it can be easily scratched with a fingernail or with a knife blade. Quartz, on the other hand, is much harder and cannot be scratched with a knife blade.
A diamond. Actually, a diamond can be scratched my other minerals.
Graphite can be scratched by materials that are harder than it, such as diamond and tungsten.
This means that it cannot be scratched.
Diamond is the hardest mineral and can only be scratched by another diamond.
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.
No, a diamond is one of the hardest natural materials and is unlikely to be scratched by an iron nail. Diamonds can only be scratched by other diamonds or by certain industrial tools designed specifically for cutting or shaping diamonds.

No, this microwave cannot be scratched easily. Even if scratched with sharp object, only the paint will come off.
Yes, metals can be scratched by harder materials. The extent of scratching will depend on the hardness of both the metal and the material causing the scratch.
Yes, it can and with laminate you cannot repair the scratch like wood.
Blockbuster have a machine that will fix any scratched disc for £2, no matter how scratched, but it cannot be repaired if the disk is shattered or snapped and will have to be replaced.
The mineral that cannot be scratched by quartz is diamond. Quartz has a hardness of 7 on the Mohs scale, while diamond ranks at 10, making it the hardest known natural material. Therefore, diamond will easily scratch quartz, but quartz cannot scratch diamond. Other minerals that are harder than quartz, such as topaz and corundum, also cannot be scratched by it.
