I'd like to confirm what you've said about diamonds breaking
during processing. The problems that come from breaking are the
result of internal flaws.

The idea of diamonds breaking may have come about from two sources.
One, an early diamond pipe that had a high carat count had such
poor quality diamonds that it wasn't economic. Two, again in the
early days, the crushing of some ore was done improperly and resulted
in reports of broken diamonds.

The third possibility, of course, is that blaming the process may
be covering up the fact that a large percentage of diamonds in a
pipe a flawed. If dynamiting the ore doesn't shatter unflawed diamonds
then itis unlikely that the crushing of kimberlite would do it.

It is well known that alluvial diamonds are always less flawed than the hard rock source. This is assumed to arise because diamonds with inclusions and other flaws are less robust, and break up more easily.
