My copy after a circa 300 BC intaglio gem from
Ionic Greece (Hermitage). March 2016
Here are my first experiments in gem engraving. Ancient carvers worked with a simple machine using oil and emery powder slurry to carve the gems (mostly chalcedony and agate):
Here are my results so far:
My first intaglio, Pegasus (agate).
This was a freehand copy after a larger Roman gem.

Once the gem was on the dop stick, I sketched the design using diamond point and silverpoint and blocked the main shapes in with large round diamond bits.
Further work was done using smaller round, wheel- and cone-shaped bits.
The biggest difficulty was not being able to see well because water obscures the view as you carve, though not as much as the thick oil and abrasive slurry, which I will try using later. Another difficulty is learning to control the rotating tool especially when making curved lines.
In parallel I have also tried my hand at caving miniature black coral sculptures using the rotary tool with steel burs, abrasive wheels, nylon brushes, and polishing wheels and compounds. This was my first time sculpting in the round.
