==> the origins of natural diamonds pdf <==

The origins of natural diamonds can be traced back to deep within the Earth's mantle, approximately 150 to 200 kilometers beneath the surface. Formed over billions of years under immense pressure and temperature conditions, diamonds begin as carbon sources, often derived from ancient organic materials or carbon deposits. The geological processes that create diamonds involve high-pressure and high-temperature environments, typically associated with tectonic plate movements. These conditions lead to the crystallization of carbon atoms into a three-dimensional structure, resulting in the formation of diamonds. Once formed, they are transported closer to the Earth’s surface through volcanic eruptions in a type of magma known as kimberlite, which solidifies into rock containing diamonds. The journey of diamonds doesn't end there; they can be found in alluvial deposits after weathering and erosion of the host rock, where they can be mined from riverbeds and ocean floors. Ultimately, the journey from deep Earth to the surface is a remarkable process, involving complex geological activities that contribute to the unique properties of natural diamonds, making them both rare and highly sought after in various industries, particularly in jewelry.
