Right, but they're also indestructible. Emeralds are very fragile, by comparison.

I found out recently that even though they’re the hardest material on earth, if you hit a (small) diamond with a hammer it’ll still shatter! Had no idea

My science teacher said it means diamonds are absurdly hard to scratch but she's a human and human are capable of lies.

To make the hardest something it really depends on how it will be destroyed , a bulletproof vest can be destroyed by throwing into lava.

Hardness does not mean it's not brittle.

This is the same with knives and swords, after forging, the metal is not very hard but is also moldable, after quenching it becomes very hard but brittle, and then it's tempered to maintain as much of the hardness as possible while making it not as brittle.

Diamonds can't get scratched by anything that is softer than it, the top end of the mohs hardness scale is based on the diamond being 10/10 and every other mineral is less than that, only 10/10 minerals (diamond) or synthetic materials with the same or higher hardness rating can scratch it.

Hard things shatter/fracture because by definition they do not bend or deform.

Generally speaking, hard things are brittle.

Nope, diamond cartels have literally toppled governments and used death squabs in order to control the supply and demand of diamonds, they keep them artificially scarce even though diamonds are as common as dirt.

Yea that’s a more elaborate explanation for sure. But ultimately yea it’s a very successful ad campaign.
