Diamonds are the HARDEST natural material.
Mankind has created harder artificial materials.
Yes, diamonds are valuable because of their rarity and desirability for use in jewelry and industry. They are formed deep within the earth under extreme pressure and heat, making them one of the hardest substances known to man.
Brown diamonds are the most common of coloured diamonds found. Chocolate is simply the name of one of the shades of natural brown diamonds. Lab-created diamonds are generally 'white' diamonds.
No, chocolate diamonds are not man-made. They are a natural variety of diamond that get their distinct brown color from the presence of nitrogen during their formation process. They are also known as champagne or cognac diamonds.
According to Wikipedia's definition of mineral, no. "A mineral is a naturally occurring solid chemical substance formed through biogeochemical processes, having characteristic chemical composition, highly ordered atomic structure, and specific physical properties."
Yes, Teflon is a man-made synthetic substance. It is a type of polymer known for its non-stick properties and is commonly used in kitchen cookware and as a coating for fabrics.

Gold is very soft, almost useless for most engineering purposes. Diamond OTOH is the hardest substance known to man.
Diamond 10
the most obvious reason being that diamonds cost a lot more than pencil lead. another reaon they are different is that diamonds are the hardest known substance to man. pencil lead is not hard at all.

ADNR's are a special manmade form of pure carbon that are harder (and denser) than natural diamonds and manmade ultrahard fullerine. I believe the answer is lonsdaleite. It is naturally made and is 58% harder than diamonds.
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.
Diamond mineral is rated on the Mohs Scale at 10, which is the highest/ hardest rating on the scale. It is the only mineral given that rating. the Mohs Scale is most useful as a field guide, where a geologist might use one mineral to mark another. This means that diamond can mark every other natural mineral. The Mohs scale is not useful for industrial or man-made materials.
Diamonds are so valuble because, after all, they are the hardest and rarest jewel known to man kind. And yes, I am only a sixth grader, not to brag (i have a great science teacher). Diam
