Question

What rocks made diamonds?

Answer 1

Hint: Firsty, we should know about “what is diamond?”. Diamonds are a solid, often inorganic, homogenous, naturally occurring substance with an ordered internal atomic structure and a defined chemical makeup. Diamonds are created under intense pressure. Within the upper mantle, 150 km down.

Complete Step by Step Solution:
High pressures are used to produce the diamonds. Deep inside the earth's crust, kimberlite, a type of volcanic rock, is created. Diamonds are discovered within these rocks.

Characteristics of Diamonds
The four main optical characteristics of diamonds are transparency, lustre, light scattering, and colour. When made of pure carbon, diamond is transparent and completely clear. Even with natural products, perfection is almost impossible to find. A diamond is the hardest material known to man. Pressure and heat are the only elements that divide this ugly piece of coal from this exquisite diamond. This gorgeous diamond didn't start off looking the way it does now. In reality, uncut diamonds are dull and sheeny, and lack brightness. After being cut, the same stones have a great lustre, though. Enhancing the stone's fire and brightness is the primary objective of diamond cutting.

Applications
Due to the excellent physical properties of diamonds, they have been used for a wide range of applications.
The most significant gemstone in the jewellery sector is the diamond.
Although yellow and brown stones are frequently used, the colourless stone is the most popular choice for jewellery.
Diamond windows are used to cover apertures in lasers, x-ray equipment, and vacuum chambers. They are manufactured from thin diamond membranes.

Note: In a method that roughly mimics the circumstances in the Earth's mantle, high pressure and high temperature can also be used to create diamonds artificially. Chemical vapour deposition is an alternative and wholly distinct growth method.
