How is a diamond made?

Simply put, diamond formation occurs when carbon deposits deep within the earth(approximately 90 to 125 miles below the surface) are subject to high temperature and pressure. Some stones take shape in a matter of days or months, while others take millions of years to materialize.

What is a diamond made out of?

Diamonds are made of carbon so they form as carbon atoms under a high temperature and pressure; they bond together to start growing crystals.

How long does it take to form a diamond?

The Natural Diamond Process

Due to the immense pressure that is present in this part of the earth, as well as the extreme temperatures, a diamond gradually begins to form. The entire process takes between 1 billion and 3.3 billion years, which is approximately 25% to 75% of our earth's age.

Are diamonds made naturally?

Diamonds are made up of billions of carbon atoms and most were formed between one to three billion years ago, deep below the earth's surface under intense heat and high pressure. Older than humankind itself, diamonds are one of nature's most incredible and unique gifts.

Why are diamonds so expensive?
