Copper "robot eye" ring with brown background & fringe with green slit mouth
Copper colored Robot eye... of course named for C3PO from Star Wars
-there are also red robot eye now called "bellagio" zoas (originally named HAL 9000)
(from 2010 a space odyssey- the robot that went crazy- represented by a red ring)
-green ring are called "Artificial Intelligence" - after the movie came out
* there IS a theme here as there should be with these names...
* perhaps the first example of a hornet ring: a dilated "zombie eye" that is hollow
