Indestructible Stuff


Hello and welcome to Tuesday and indestructible stuff day and today it's diamonds everyone has heard of diamonds and how tough they are. In fact they are one of the hardest natural substance in the world.

Diamonds are smooth and dull when they come out of the ground and have to be cut into geometric shapes to make them sparkle. Long ago this could only be done with another harder diamond, however, today lasers are used.

Diamond is made from carbon, the same thing as coal and the soft dark grey graphite that give pencils their mark marking power. So why is diamond so much harder?

Well diamond can only be formed when carbon is squeezed incredible hard, and this can happen in two ways. Very deep inside the ground as in very deep like 150-200 km down, as rocks push against each other. The diamonds then move up to the surface in volcano eruptions.

Or it can happen when an asteroid or meteorite crashes into the earth with incredible crushing power.

Of course we now can make artificial diamonds by squeezing carbon in a lab.

I had just read that there's a new process where they can make a diamond in a few minutes! Better than other fake diamonds. ?? That will change things, I'm sure.
