How Diamonds Form. Some stones take shape in a matter of days or months, while others take millions of years to materialize. The colour is affected by how the nitrogen is scattered through the stone.

Obviously in that part of the earth it's very hot. But carbon typically takes mineral forms that are much less exciting than diamond! In the past 50 years alone, scientists have learned a lot about how diamonds form and how they’re transported to the earth’s surface. Web diamonds occur most often as euhedral or rounded octahedra and twinned octahedra known as macles. Web the world’s love of diamonds had its start in india, where diamonds were gathered from the country’s rivers and streams. Web diamonds are formed naturally in the earth’s mantle under conditions of extreme temperature and pressure. By bryan boyne (g.g.) diamond is composed of pure carbon. Web diamonds are not only formed under the heat and pressure of the earth’s gravity, but can form in the midst of a collision between earth and an asteroid. Volcanic eruptions brought the diamonds up to the surface. Web 2 days agoaustralia's unrelenting march towards the medal round at the netball world cup in cape town has continued with the diamonds cruising past scotland.
Obviously in that part of the earth it's very hot. A recurring pattern of landmass formation and fragmentation that has. At temperatures higher than 2100 o f (1150 o c) and pressures 45,000 times greater than at sea level, crystals formed, resulting in the hardest. If single nitrogen atoms replace carbon, the diamond can be bright canary yellow. Web answer (1 of 30): Diamond formation in subduction zones diamonds are also thought to form in subduction zones, a.k.a. The extreme pressure and heat at these depths cause carbon atoms to bond, creating a diamond's crystalline structure. Diamond’s carbon atoms are bonded in essentially the same way in all directions. More than a billion years ago, 100 miles (161 km) or more beneath the earth’s surface, in a cauldron of extreme temperatures and high pressure, carbon atoms bonded tightly together. Web diamond stones are weighed in carats (1 carat = 200 milligrams) and in points (1 point = 0.01 carat). Web diamonds are formed naturally in the earth’s mantle under conditions of extreme temperature and pressure.
