What Are Earth Mined Diamonds and How Are They Formed?

Earth mined diamonds are carbon crystals that form deep within Earth's mantle under extreme pressure and temperature conditions. Most diamonds crystallize at depths of 150-200 kilometers within cratons at temperatures of 900-1300°C. The oldest dated diamonds are 3.5-3.3 billion years old from Diavik and Ekati mines in northern Canada. Kimberlite or lamproite volcanic eruptions that occurred 145-66 million years ago brought diamonds to the surface. Diamond density measures 3.52 g/cm³, which is 56% higher than graphite at 2.26 g/cm³. Pressure inside diamond inclusions can reach 24 GPa, equivalent to the bottom of the mantle transition zone. Natural diamonds require millions of years to form through geological processes that cannot be replicated artificially. The following sections explore how natural diamonds differ from synthetic alternatives and the specific geological conditions that create these precious stones.

How Do Natural Diamonds Differ From Lab Grown Diamonds?

Natural diamonds differ from lab grown diamonds primarily in their formation timeline and growth environment. Natural diamonds formed in Earth over millions of years grow differently from lab diamonds created in weeks. Lab-grown diamonds produced via HPHT method use chambers heated to 1300-1600°C with pressures above 870,000 pounds per square inch. The CVD method uses chambers heated to 900-1200°C with microwave beams splitting methane molecules. HPHT can produce colorless diamonds of 10+ carats in several days to weeks. CVD growth process takes 3-4 weeks, resulting in flat, tabular crystals. Natural diamonds contain unique inclusions and growth patterns that reflect their billion-year journey through Earth's mantle. These differences in formation create distinct crystal structures that gemologists can identify using specialized equipment.

What Geological Conditions Create Earth Mined Diamonds?

The geological conditions that create earth mined diamonds include extreme depths, pressures, and temperatures found only in Earth's mantle. Rare "superdeep" diamonds form at depths of 200-800 kilometers below the lithosphere. Some younger diamonds around 90 million years old were found at Jagersfontein and Koffiefontein in South Africa. One gigapascal equals 10,000 times atmospheric pressure at sea level, demonstrating the extreme conditions required. Most deposits contain multiple diamond populations varying in age. Famous superdeep diamonds such as Hope, Koh-i-Noor, Lesedi La Rona, and Cullinan formed at 360-800 kilometer depths. These formation conditions occur exclusively in stable continental regions called cratons. Understanding these geological requirements helps explain why natural diamonds remain rare and valuable compared to laboratory alternatives.

Why Do People Value Earth Mined Diamonds?

People value earth mined diamonds for their billion-year formation history and proven investment performance. Natural diamonds appreciate steadily over time, such as the Fancy Intense Pink 4.59-carat diamond that sold for $625,000 per carat in 2010.
