Almost 100 million years ago, a volcano “pipe” was created. This unusual diamond bearing formation accumulated in various stages: First molten rock deep inside earth’s mantle swept through a shallower zone where diamonds had crystallized before and then worked its way to earth’s surface. The magma rose slowly in a thick mass, allowing heat and pressure to disintegrate the crystals conveyed. Later on a last, one more violent gaseous eruption fragmented the rock it cooled enough to let diamonds survive. Three distinct forms of the original magma spread across at least eighty acres at the surface. The east half of the structure is where diamonds can be found.
Then in summer 1906 John Wesley Huddleson became the first person to find diamonds at their original source, on the surface of his farm. That 243- acre tract that he had purchased in July 1905, included over three-fourths of the volcano formation.
