Excavating the Truth Like it? Share it! The common element between coal and diamonds is carbon. Is it then possible to transform a piece of coal into a diamond? There are many theories to both support and negate this question. It is difficult to believe that any relation exists between the dark brownishblack lumps of coal and shimmering diamonds.

The girdle of the diamond is formed first, and then come the various facets. This is a painstaking stage that required accuracy, or else the finished diamond will be virtually worthless. Only the first 18 facets are cut first the table, culet and 8 facets each on the crown and pavilion. This is a substage called 'Blocking'.
