How Diamonds Form Deep in Earth’s Mantle - Geological Process Explained #3738084 (License: Personal Use)

This diagram depicts Earth’s interior layers, highlighting the mantle region where carbon crystallizes into diamonds under high pressure (45-60 kbar) and temperature (900-1400°C) within the diamond stability zone. A red magma plume ascends rapidly through a kimberlite pipe, carrying diamonds upward before they can revert to graphite. The surface shows a volcanic vent, indicating the eruption that brings diamonds to accessible depths.

Used in educational geology articles, museum exhibits, or diamond industry explainers to visualize deep-Earth diamond formation and transport. Matches user intent for learning about natural diamond origins, kimberlite pipes, and mantle processes.
