Roughing out the girdle

Bruting a diamond is the process of grinding two diamonds against each other.  Here we can see the diamond cutter’s bruting machine which is being used to make the diamond round.

Since only diamond can cut diamond the flat disk on the bottom is diamond powder that has been compressed and glued together.  Both the diamond disk and the diamond being bruted are glued onto a bruting dop and heated.  The glue hold them in place – that is some serious glue!
