Diamond is the hardest known natural substance. It is also chemically resistant and has the highest thermal conductivity of any natural material. … Diamond also has special optical properties such as a high index of refraction, high dispersion, and adamantine luster.
What are the special properties of a diamond?
Besides the hardness, diamond provides an impressive combination of chemical, physical and mechanical properties:
- Low coefficient of friction.
- High thermal conductivity.
- High electrical resistivity.
- Low thermal expansion coefficient.
- High strength.
- Broad optical transparency from ultra violet to infra red.
What is the unique structure of a diamond?
The crystal structure of a diamond, called a face centered cubic lattice, derives from the way each carbon atom joins four other carbon atoms in regular tetrahedrons (triangular prisms). It is possible to cleave, or split, a diamond, along its crystal face (grain), such that each side of the cleavage remains smooth.

Which physical properties make diamonds so valuable?
Diamonds have a range of physical properties which give them value. They are one of the hardest materials known to man, and can cut glass, marble and granite. They are thermal conductors, resistant to pressure and act as electrical insulators.
Why is diamond so hard?
The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth.
What energy does Diamonds have?
Diamond imparts fearlessness, invincibility and fortitude. It clears emotional and mental pain, reducing fear and bringing about new beginnings. Stimulates creativity, inventiveness, imagination and ingenuity. It brings clarity of mind and aids enlightenment.
How much are real diamonds worth?

What is the structure of diamond called?
Diamond is a form of the element carbon with its atoms arranged in a crystal structure called diamond cubic.
Why does diamond not conduct electricity but is very strong?
Diamond is a giant covalent structure; each valence electron (outer shell electron) of every carbon atom forms a covalent bond, which means that there are no free electrons. Since electrical conductivity relies on the flow of free electrons, diamond is not a good conductor.
How do diamonds benefit humans?
DIAMONDS AS AN INDUSTRIAL APPLICATION
One of the most common uses of a diamond, besides being made into jewellery, is the use of it in the industrial industry. Due to a diamond’s remarkable strength, they have become extremely effective as cutting, polishing and drilling tools.
What makes a diamond so valuable?
The earliest recorded cultures used diamonds to portray strength, the value of love, and even instruments of magic. That value is likely due to a diamond’s natural strength and unique visual appearance in combination with its relative rarity. Even a low-grade gem-quality diamond is still a thing of value and beauty.

Is Diamond a good conductor of electricity?
Most diamonds are electrical insulators and extremely efficient thermal conductors. Unlike many other minerals, the specific gravity of diamond crystals (3.52) has rather small variation from diamond to diamond.
Can be scratched by a diamond property?
As you can see, diamond is a 10 on the Mohs Hardness Scale. Diamond is the hardest mineral; no other mineral can scratch a diamond. … It can be scratched by topaz, corundum, and diamond. Quartz will scratch minerals that have a lower number on the scale.
Is Diamond a gemstone?
Diamond, a mineral composed of pure carbon. It is the hardest naturally occurring substance known; it is also the most popular gemstone. Because of their extreme hardness, diamonds have a number of important industrial applications.
