Facts on Diamonds, Diamonds are the hardest natural substance known to man. They are 58 times harder than the next hardest mineral on Earth. The only substance that can scratch a diamond is another diamond. A diamond over one carat in weight is one in a million.
Diamond is a solid 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.
Fact #1 : Why are they so precious ?
It is one of the most admired stones on the planet earth and has been one of the most sought after jewels for thousands of years. Diamonds were formed billions of years ago and are extremely rare because so few are able to survive the difficult journey from the pits of the earth to reach the earth’s surface.
Fact #2 : How Old is a Diamond ?
Most natural diamonds have ages between 1 billion and 3.5 billion years. Most were formed at depths between 150 and 250 kilometres (93 and 155 mi) in the Earth’s mantle, although a few have come from as deep as 800 kilometres (500 mi).
Do you Know ?
Red Diamonds, For example, most white diamonds are discounted in price when more yellow hue is detectable, while intense pink diamonds or blue diamonds (such as the Hope Diamond) can be dramatically more valuable. Of all colored diamonds, red diamonds are the rarest.
Fact #3 : Which is harder than diamond?
Buckypaper. It is well-known since the late 20th-century that there’s a form of carbon that’s even harder than diamonds: carbon nanotubes. By binding carbon together into a hexagonal shape, it can hold a rigid cylindrical-shaped structure more stably than any other structure known to humankind.
Fact #4 : Who found the first diamond ?
The earliest diamonds were found in India in 4th century BC, although the youngest of these deposits were formed 900 million years ago. A majority of these early stones were transported along the network of trade routes that connected India and China, commonly known as the Silk Road.
Fact #4 What can break a diamond ?
As an example, you can scratch steel with a diamond, but you can easily shatter a diamond with a hammer. The diamond is hard, the hammer is strong. Whether something is hard or strong depends on its internal structure. A diamond is made entirely of carbon atoms which are joined in a lattice-type structure.
Fact #5 : Are Diamonds bulletproof ?
It doesn’t seem unreasonable to wonder whether diamonds are bulletproof, since diamond is the world’s hardest natural material. Diamonds are not however bulletproof in general, as while they are hard, they are not particularly tough and their brittleness will cause them to shatter when struck by a bullet.
Which Diamond is the best ?
When it comes to choosing clarity, you will get the best value by picking a stone graded VS2 or SI1. Higher-clarity diamonds are cleaner, but this is visible under magnification. To the naked eye, a VS2 diamond, for example, looks as clean as one of a higher clarity grade. Facts on Diamonds
