Geologists feel that the diamonds in all of Earth's industrial diamond deposits ended up formed inside the mantle and delivered to the surface by deep-supply volcanic eruptions. These eruptions deliver the kimberlite and lamproite pipes that happen to be sought after by diamond prospectors.
Adequately small diamonds can kind during the cold of Place because their decrease surface area Electrical power helps make them extra stable than graphite. The isotopic signatures of some nanodiamonds show they ended up shaped outside the house the Solar Procedure in stars.[80]
Most diamonds utilized as gemstones are generally clear with small tint, or white diamonds.
