No. No substance known to exist is harder than diamond and especially no other element.
Diamonds are harder than chalk.
Diamonds aren't always sharper, but they can be manufactured in such a way. Diamonds are harder than steel.
Yes
Yes, diamonds can cut glass, because diamonds are harder than glass.
No, diamonds are harder than coal. Diamonds are one of the hardest natural materials on Earth, while coal is relatively soft and brittle.
Diamonds are the hardest mineral known. Metal refers to metallic materials, and there are many of them. In order to give a 'yes' or 'no' answer to your question, you must specify which metal. Always, however, diamonds are harder than any metal; the number of times harder, then depends on which metal is being compared to diamond in hardness.
Yes, diamonds are harder than quartz on the Mohs scale, so diamonds can scratch quartz.
Yes, diamonds are harder than steel. Diamonds are the hardest natural substance on Earth, scoring a 10 on the Mohs scale of mineral hardness, while steel typically ranges from 4 to 8 on the same scale.
No. Diamonds cut glass because diamonds are harder than glass. Quartz is not as hard as diamond.
easier than diamonds, harder then graphite
No, diamonds are harder than enamel. Diamonds rank as the hardest natural material known, scoring 10 on the Mohs Scale of Hardness, while enamel, the outer layer of teeth, ranges from 5 to 7 on the scale.
Synthetic diamonds and real diamonds both have the same level of hardness. They both rank 10 on the Mohs scale of hardness.
