The resources of semi-precious stones in Zimbabwe are estimated to be vast. Their total value is estimated at US$20 billion. The country hosts about 33 different types of semi-precious minerals. The minerals are under-explored (more so than other minerals), so the estimated number of types and value could be way below the actual.
