diamond mine
Carbon crystal excavation
A diamond mine is a site where diamonds are extracted from the earth, either through open-pit excavation or underground tunneling.
The term extends to anything exceptionally rich in valuable material: That old archive turned out to be a diamond mine of historical documents.
The figurative sense emphasizes abundance and untapped potential.
