Natural diamonds are diamonds that are naturally made in the earth over 1 to 3 billion years. Natural diamonds start their lives as carbon dioxide and over time with extensive pressure and heat they will naturally modify to a solid stone. The stones are pushed to the surface by volcanic eruptions and put them within our reach through mining.

A natural diamond is formed in the Earth's mantle over millions of years through natural processes, while a lab-grown diamond is created in a laboratory using advanced technological processes.

Both have the same physical and chemical properties, but lab-grown diamonds are typically less expensive and have less impact on the environment than natural diamonds.

Natural diamonds, i.e. mined diamonds, are generally more expensive than laboratory-grown diamonds.

This is mainly because the price and availability of diamonds is controlled by a small group of people.

The production of natural diamonds involves more work and natural diamonds are more well-known than lab-grown diamonds, so they tend to cost more.

However, a lab-grown diamond is the same as a natural diamond, but lab-grown diamonds cost significantly less.

This is because the production process is more cost effective and it is a renewable resource.

It takes millions to billions of years for a diamond to form under high pressure and temperature conditions deep within the Earth's mantle. It’s impossible to know exactly how long it takes diamonds to form because the formation process isn’t continuous.

Diamonds are made out of carbon atoms that have been subjected to immense heat and pressure deep within the Earth's mantle.
