hardness.
"Mohs" hardness is the resistance to scratching and is a relative measure e.g. Diamond will scratch Quartz and Quartz will scratch Gypsum etc. Another measure of hardness is the Brinell hardness test, which measures resistance to indentation and is a more absolute test of hardness.
All minerals can be scratched if you used the right scratcher. Diamond can only be scratched by another diamond, and is most resistant to being scratched. In the jewelry world any thing harder than a 7 on the Mohs hardness scale is consider resistant to scratching.
