Diamond material is carbon. As a tutorial, from Wikipedia:
"Carbon is the 15th most abundant element in the Earth's crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen. It is present in all known life forms, and in the human body carbon is the second most abundant element by mass (about 18.5%) after oxygen. This abundance, together with the unique diversity of organic compounds and their unusual polymer-forming ability at the temperatures commonly encountered on Earth, make this element the chemical basis of all known life."
This fact, then begs the question: why would 'man' want to 'make' carbon?
Diamond is the strongest material know to man.
Diamond is the hardest material made by man. It is composed of carbon atoms arranged in a strong crystal lattice structure. Its hardness is due to its unique atomic structure, which makes it highly resistant to scratching or indentation.

true.
Diamond is the hardest known natural material on Earth, scoring a 10 out of 10 on the Mohs scale of mineral hardness.
The Diamond Man was created in 1924.
No this is not at all true, for no matter how far science has advanced they have failed to make a invisible man.
true
Yes Polyester is a synthetic man made material.
No, sandpaper cannot scratch a diamond because diamonds are the hardest natural material on the Mohs scale of mineral hardness. Sandpaper is designed to abrade or scratch softer materials, not harder ones like diamond.
The hardest material known to man is currently called lonsdaleite (a carbon form), which is approx. 58 % harder than a diamond and then there is wurtzite boron nitride which is about 18% harder than diamond. Both occur in nature just like diamonds.
There are substitute faux-gem stones that jewelers use to display and show off their settings. Some are man-made; others are semi-precious stones, such as quartz or crystal, even white sapphire. These substitutions are for 'looks' only. There is no substitute material for diamond when it comes to hardness.
