Does Diamond Hardness Really Matter?
Tenacity. Nothing can scratch a diamond, but there are plenty of things that can break or chip it. If you took a hammer to a diamond, for instance, you would smash it into many little pieces. Tenacity measures a mineral's resistance to blows. Diamonds, like most minerals, are considered brittle, which means they can't withstand a blow.Web
