How and where do diamonds form? 4 spectacular origin stories Big Think
Web a mined, natural diamond is a crystallized carbon structure that is formed beneath the earth’s surface over millions (or sometimes billions) of years under the perfect conditions of heat and pressure. Each natural diamond is made of pure carbon, compressed by earth’s pressure over time, and is the hardest substance on earth that exists naturally. Diamonds are found at a depth of approx. The result was the hardest gemstone on earth — diamond. Web gemological institute of america | august 15, 2022 in addition to their revered status, diamonds have an extraordinary geological backstory unlike any other material found on earth. Web coal could be present in the target area of these impacts and could serve as the carbon source of the diamonds. Colored gemstones tell scientists about the crust; Web diamonds formed 90 million to 3 billion years ago at a depth of 90 to 400 miles beneath earth’s surface. Kimberlite weathers quickly, releasing the diamonds and they go downhill, either by gravity or water, and are then carried by river systems downstream — possibly hundreds of.

Diamonds were formed over 3 billion years ago deep within the earth’s crust under conditions of intense heat and pressure that cause carbon atoms to crystallise forming diamonds. Web diamonds form as carbon atoms crystalise below the earth's crust in extremely hot and highly pressurised conditions. Web coal could be present in the target area of these impacts and could serve as the carbon source of the diamonds.
