Why do diamonds and coal look different?

How is diamond and coal different?

The chemical difference is identical, but physically, diamond molecules are stacked neatly into uniform lattices, which is why they are so hard and crystal clear. Coal molecules, by comparison, are randomly stacked, which gives coal its colour and the fact that it burns and can easily be broken into smaller pieces.

Are diamonds really just coal?

Over the years it has been said that diamonds formed from the metamorphism of coal. According to Geology.com, we now know this is untrue. “Coal has rarely played a role in the formation of diamonds. … The diamonds form from pure carbon in the mantle under extreme heat and pressure.

Is coal more useful than diamond?

A one pound diamond is worth anywhere from $2-6M depending on its grade. A pound of coal is worth a few pennies. Paradoxically, though diamonds cost more than coal, coal is more valuable.

How long does it take for coal to become a diamond?

That is miles upon miles between the earth’s surface. Due to the immense pressure that is present in this part of the earth, as well as the extreme temperatures, a diamond gradually begins to form. The entire process takes between 1 billion and 3.3 billion years, which is approximately 25% to 75% of our earth’s age.

Can peanut butter turn into diamonds?

Peanut butter can be converted into diamonds by subjecting it to extremely high temperature and pressure. Be warned- the quality of diamond produced by the peanut butter won’t be something to write home about. The resulting diamonds are typically very small and tend to be muddy in color.

What Rocks are diamonds found in?

Background. The diamond is the hardest natural substance known. It is found in a type of igneous rock known as kimberlite. The diamond itself is essentially a chain of carbon atoms that have crystallized.

Why diamond is white?

So What Makes a White Diamond White? Similarly to most other colored diamonds, white diamonds get their color from the presence of sub-microscopic inclusions. These inclusions cause the light that passes through the stone to scatter, giving it a translucent “milky” white face-up appearance.

Is diamond a natural element?

Diamond is a form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. At room temperature and pressure, another solid form of carbon known as graphite is the chemically stable form of carbon, but diamond almost never converts to it.

Why do diamonds shatter?

Because of diamond’s perfect and easy cleavage, it is vulnerable to breakage. A diamond will shatter if hit with an ordinary hammer. … Diamond has a cleavage plane and is therefore more fragile in some orientations than others. Diamond cutters use this attribute to cleave some stones, prior to faceting.
