Birth of a Yogo

The first four pictures show the rough from various angles

This second picture shows a broken surface most likely chipped off in the mining process.

Note the deep pits in the surface that will effect recovery

This view shows the thin end that will be sawed off to produce another smaller stone.

This picture shows the two pieces after sawing.

This is the stone after preforming. Note the pits left in the surface that will be the table.

This is the other side of the stone at this point.

Here the stone is dopped to cut a cone on the back.

The pavilion is now defined but there is enough left to remove when the stone is finished.

Then I remove the stone and redop to cut and polish the crown. This is a preference that works well for me but many cutters finish the pavilion first

Here there has been some material removed around the table and the table polished. Note that there are still pits in the table but they are positioned so that they will be removed when the crown facets are cut.

Here the crown has been cut to very close to the finished surface.

The polishing begins with the star facets. The order is important since cutting from lowest angles to highest leaves sharper facet edges.

Then the main facets.

And last but not least the crown break facets. The top of the stone is done at this point.

Here the stone has been transfered and the pavilion facets cut.

The pavilion mains are then polished.

And lastly the pavilion break facets are polished and the girdle smoothed out The stone is done at this point.

This is not the greatest picture but it shows the result after cleaning it up, removing the last bits of dop wax with alcohol.
