Canadian ammolite brooch and pendant set in silver

Ammolite is a beautiful gemstone.  My client supplied these pieces and they seemed to me to need a secure, but minimal setting to focus attention on the stones themselves.

The pendant piece is double sided and this setting allows both sides to be on display.  It is fairly symmetrical and relies on the shape of the stone to keep it secure.  The brooch piece is one sided, so there is a silver plate with the brooch pin and revolver safety catch.  The stones could be removed from the mounts without damage if required.
