Heart Shaped Tanzanite
The first three pictures show the rough from various angles
Here the stone is roughed to the general shape
Here the stone is dopped to rough in the back facets.
The next step is to remove the stone and redop to cut the crown.
Here there has been some material removed around the table and the table polished.
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.
Then we add wing facets to the flatter sides to aid brilliance.
Then break facets are added
Then the notch is cut and the girdle polished.
This picture shows the result after cleaning it up, removing the last bits of dop wax with alcohol.
The last step is heat treating. This burns out the brown axis and brings out the best blue color
