Diamonds are the hardest gems. In gemological terms, hardness means resistance to scratching. A diamond can scratch other gems, but nothing can scratch a diamond except another diamond. Cutting and faceting of diamonds can be done only with other diamonds because only diamond can cut diamond..
Also, can a diamond be scratched by anything?
Diamond can only be scratched (abraided) by another diamond. All other stones will be scratched by diamonds however. Diamonds have a 10 out of 10 for hardness on the Moh's scale, which determines the strength of bonds between the molecules in an item.
Likewise, can diamond be scratched by concrete? Inevitably, if the diamond bond is softer than the hardness of the concrete, the diamonds will wear out quickly. If the diamond bond is harder than the concrete, the diamonds will resist cutting into the concrete, essentially producing little wear and a negligible and uneven scratch pattern.
Similarly, you may ask, can a diamond cut another diamond?
The hardness of the diamond prevents arbitrary cleaving; instead, the shape of a diamond cut is related to the natural shape of the rough stone. Using these imperfect stones as cutting grit belies the main theory: only a diamond can truly cut another diamond.
Can you scratch a diamond with a knife?
The diamond is the hardest mineral found on this earth with the hardness of 10. It is 40 times harder than Corundum which is 9 on the Moh's Scale. This is the key concept that makes it even possible to cut diamonds by the way. A diamond can scratch other gems but it can only be cut or scratched by itself.
