So, what about that question about diamond hardness? A diamond’s hardness generally refers to the Scale of Mineral Hardness created by Friedrich Mohs in 1812. Mohs laid out a “scratch hardness” scale, which is a way to measure of how resistant a mineral is to scratching or breaking.

On the Mohs scale, a diamond gets a 10 out of 10. No other gemstone can scratch a diamond except another diamond. What other gemstones are highly rated on the Mohs scale? Both sapphires and rubies get a high rating of 9 on the Moh’s Scale, while emeralds are a little softer, rating at 7.5.

But are diamonds invincible? Absolutely not. In fact, a common way diamond rings get cracked or chipped is when they are hit against a granite countertop. Granite is tough stuff!
