10.  PIPE MINING REFERS TO THE EXTRACTION OF DIAMONDS FROM
VOLCANIC PIPES.
 TYPICALLY, A VERY LARGE AREA HAS TO BE COVERED. AN
AVERAGE OF 250 TONNES OF ORE MUST BE MINED IN ORDER TO
PRODUCE A ONE-CARAT GEM QUALITY POLISHED DIAMOND
HOW DIAMONDS ARE MINED

11.  THIS PROCESS INVOLVES THE EXTRACTION OF DIAMONDS
FROM RIVERBEDS OR OCEAN BEACHES
 MILLIONS OF YEARS AGO, AT THE TIME THE DIAMOND PIPES
WERE FORMED, SOME DIAMONDS WERE WEATHERED OUT OF
THE PIPES AND CARRIED GREAT DISTANCES ALONG RIVERS AND
EVEN INTO OCEANS
