Diamonds rise to the Earth's surface in rare molten rock, or kimberlite, that originates at great depths, rising through a pipe like opening called kimberlite pipes, and erupting in small but violent volcanoes. A volcanic cone forms above the kimberlite pipe and the surrounding deposits of material containing diamonds. This cone is very small in comparison with volcanoes like Mount St. Helens, but the kimberlite magma flow starts at least 3 times deeper in the Earth. Kimberlite pipes and magmas are the elevators that bring diamonds to the Earth's surface where they can be discovered millions of years later.

Laboratory grown diamonds in the Solaura Collection are grown on the Earth's surface and for our benefit, use and pleasure, are "discovered" only hours after they are formed.
