December 9, 2022 by July. Most geologists find diamonds by looking for kimberlite pipes. Kimberlite is a type of rock that is formed in the upper mantle of the earth and is brought to the surface by deep-seated volcanic eruptions. The rock is composed of many different minerals, but diamonds are only found in a small percentage of kimberlite pipes.Diamond within a few eclogites has been studied by computerized axial tomography (CAT-scan) techniques. There diamond is found in between the major silicate minerals along pathways where metasomatic fluids usually traveled (Keller et al., 1999; Anand et al., 2004), although it is unknown whether diamond always has this spatial relationship.Aug 17, 2023 · A few true metamorphic rocks are found due to the alteration of the rocks immediately surrounding and in contact with the igneous intrusions.

Divide the weight of the crystal by the weight of the crystal in water. If you divide the weight of the gem with the weight of the suspended gem in water, you’ll get the gem’s density. Diamonds have a density of 3.5 - 3.53 g/cm3. If the results are less than this number, you have a different gemstone. kapop tree Diamond forms under high temperature and pressure conditions that exist only about 100 miles beneath the earth’s surface.
