Role of the U.S. Geological Survey (USGS)

The USGS reports deposits that seem likely to contain gemstones. It is not a function of the USGS to exploit such resources.

USGS geologists perform continuing research on kimberlites, the initial source of diamonds. Not all kimberlites are diamond bearing, and some of the research is directed to learning what indications you look for during exploration to distinguish fertile from barren kimberlite.
