What is the predominant source of diamonds in Russia?

The predominant source of diamonds in Russia is primary sources. This refers to natural deposits where diamonds are formed within the Earth’s mantle and brought to the surface through volcanic eruptions, typically found in kimberlite pipes. Russia, specifically regions like Yakutia, is renowned for its rich deposits of diamonds, predominantly sourced from these primary locations.

Alluvial deposits pertain to diamonds that have been eroded from their original volcanic sources and carried away by water, where they settle in riverbeds or other locations, but this is not the primary method of extraction in Russia. Secondary sources would indicate diamonds that have been sourced from already existing materials, while artificial diamonds are man-made and do not contribute to natural diamond sourcing. Thus, primary sources are critical in understanding the overall diamond production landscape in Russia.
