Talc is the softest mineral and can be scratched by any other mineral.
Corundum- which can only be scratched by diamond. Diamond cannot be scratched by any other mineral.
Mineral X could be anything. Diamond is the hardest mineral (10 on Mohs' scale) and can scratch all other minerals including another diamond.
Hardness - measure of how easily a mineral is scratched.
For simple identification purposes you should ask: what is the hardness of the mineral compared to other minerals; what is the color (streak) of the mineral when scratched on an unglazed porcelain ceramic surface; and does the mineral react with dilute hydrochloric acid or vinegar, indicating whether or not it's a carbonate mineral. Other identifiers would be the mineral's specific gravity, lustre, and crystal classification.
A minerals hardness is its relative ability to scratch or be scratched by other minerals. Diamond, for instance, can scratch all other minerals because of its hardness. Streak is the color of the mineral when powdered. This is usually accomplished by the streak test (swiping the mineral across an unglazed porcelain surface) which reveals a mineral's streak color, which may differ from the color of the specimen being tested.
A diamond. Actually, a diamond can be scratched my other minerals.
A minerals hardness is the ability to scratch or be scratched by other minerals and streak is the colored powder of a mineral that comes off when being scratched.
In 1822 scientist Friedrich Mohs developed a scale to measure the hardness of minerals. A mineral will scratch other minerals softer than itself and will be scratched by minerals that are harder.
Hardness is the ability of a mineral to resist being scratched. A diamond is the hardest mineral--which means that no other mineral can scratch it.

Corundum- which can only be scratched by diamond. Diamond cannot be scratched by any other mineral.
A diamond is the hardest mineral. A diamond can scratch all other minerals or rocks and cannot be scratched by another mineral or rock except another diamond.
Mineral X could be anything. Diamond is the hardest mineral (10 on Mohs' scale) and can scratch all other minerals including another diamond.
