The process is always to take pre-improvement pictures, pinpointing the inclusion removal element and finally getting rid of the diamond facets and noises.[sixty two]
Diagram of the volcanic pipe Geological evidence supports a design during which kimberlite magma rises at four–twenty meters for each next, building an upward route by hydraulic fracturing on the rock. since the stress decreases, a vapor stage exsolves with the magma, which really helps to continue to keep the magma fluid.
