How a Diamond is Formed. In order for diamond to form there must be an available source of carbon and relatively narrow ranges of temperates and pressures must align. This happens around 100 miles below the crust. Once crystalized the diamonds must be rapidly transported to the surface without undergoing substantial change.
Twinning Wisps â This inclusion is a result of growth defects in a diamondâs crystal structure. During a diamondâs formation process, it may stop growing due to unfavorable conditions and twinning wisps are form when growth restarts (say for example thousands of years later) in a different direction.
