The creating and fabrication of an aquamarine pendant

Here are the elements that I wanted to put together as a pendant: a large ( 23.63 carats), drop shaped, greenish blue aquamarine cabochon, translucent with inclusions and a great depth, and the top part of a brass military collar badge (that says 'ubique', meaning 'everywhere').

This is a photoshop rendering that I made. Of course the final result will be different, as the proportions will be different, and as the bezel will hide some of the outline of the stone. Something I should have taken into account at this stage.

 Here is the pendant ready to receive the stone.
