Primary and secondary deposits of diamonds - Diamant-Gems

Diamond deposits can be divided into two categories : primary and secondary deposits. Primary deposits are volcanic craters that have caved in on themselves and contain vertical kimberlite “pipes” that shrink until they crack (1). These can also occur as long, narrow veins, both vertical and oblique that spread over several kilometres.
