Lonsdaleite is a mineral formed when a large asteroid that contains a lot of carbon collides into Earth, creating a different type of diamond with a hexagonal structure. It is theorized to be up to 58% harder than regular diamond
I have some stones that can't be scratched by corundum even by diamond. I have no idea what stones they are. They do not seem like diamond at all. I have just uploaded the testing video.
Another diamond will scratch a diamond. People saying a high temp or TNT are not talking about hardness. Although diamond is very hard, it is in fact rather weak and can be smashed with a hammer.
The real Slim Shady: I proved to myself that a diamond can be smashed with a hammer because my diamond broke into two pieces! Luckily the client didn't know of this "experiment"!
Myfacewhen: Yes, diamonds do bounce around because of their greasy lustre, however, I really whacked a diamond with such force that it broke in two pieces perhaps because of its cleavage...
Yeah, the hardness in the Mohs scale is the resistance to being scratched, not overall structural strength or something like that. Gems and such that are on the higher levels of the Mohs scale do tend to be pretty strong, and might be able to withstand some hits from a hammer, but they aren't necessarily related, I think there are some who can be scratched easily but are stronger against being hit, like Jade or Agate.
Lartetite can scratch diamond. It's available only on Neptune. It's crystalline in the particle size of around 10 to 50 um. Concentration on Neptune is just 2 to 3 ppb.
Can someone please do an upgrade to this video and crush rocks for us? So we can test the hardness. See it in action. Squish a piece of talc. How much pressure does it take to pulverize it? Of course it would be interesting to go up the mohs scale crushing each one. And seeing the force needed. But just not with my stones. 😵😵🤣😂🤣😂🤣
So would tooth enamel- being the hardest substance in the body - rate about 5.5? I think it is closest to apatite, but steel dental tools do not scratch it. For comparative reasons I think It would be interesting to see a video about where hair, bones, teeth and fingernails would rate on the scale.
