Quartz, topaz, emerald, corundum.
Diamonds can only be scratched by other diamonds. Diamond is the hardest natural mineral.
Compared to other parts of the body, yes. Compared to diamond or some rocks, no.
because rocks are extremely hard to cut or even crack
Hard matrix is supposed to be used for digging hard rocks and soft matrix for soft rocks. It's quite confusing to me
All diamonds are minerals, and most all diamonds are rocks in their raw form: exceptionally hard, clear rocks.
A diamond can only be scratched by another diamond due to its hardness. No other material is hard enough to scratch a diamond.
Rocks that are harder than a nail, which typically has a hardness of around 5 on the Mohs scale, include quartz, topaz, and diamond. Quartz, with a hardness of 7, is commonly found in various types of rocks. Topaz ranks at 8, while diamond is the hardest known natural material, scoring a 10 on the Mohs scale. Other hard rocks include corundum and garnet, which also exceed the hardness of a nail.
The hardEST is a diamond, and some other hard ones are corundum and topaz. If you look up Moh's hardness scale, it will show you some.
No. Diamond is the hardest substance we know of. the only thing harder is other diamonds.
Diamond is hardest Diamond cuts glass Glass does not cut diamond
No. You can't make a solid diamond sword there needs to be high pressure and heat to even make a shapeless diamond. To add onto this answer-even if it was possible, diamond would not be a suitable blade material. It is hard, but that does not mean it is strong. It could not withstand the lateral forces swords are subject to.
Yes, quartz is considered a hard mineral ranking 7 on the Mohs scale of hardness, making it able to scratch most other minerals. However, there are harder minerals such as diamond and corundum that can scratch quartz.
