💎What is a Diamond?

A diamond is a precious gemstone made of pure carbon that has been subjected to intense heat and pressure deep within the Earth's crust. Due to its exceptional hardness and brilliance, diamonds are highly prized in jewelry and industrial applications.

Diamonds symbolize love, luxury, and status. They are widely used in engagement rings, fashion accessories, and industrial tools due to their unmatched durability and cutting precision.

Formation and Types of Diamonds

How Diamonds Are Formed

Diamonds form under extreme pressure and high temperatures deep within the Earth’s mantle over billions of years. Some diamonds are also created in laboratories using high-pressure, high-temperature (HPHT) or chemical vapor deposition (CVD) methods.

Types of Diamonds

Diamonds are classified based on color, clarity, and origin:

  • Natural Diamonds – Mined from the Earth.
