Amber Fish on a string

Found in an abandoned dig in the desert near Algiers, this amber fish on a string is actually an orichalcum detector that can be very useful if you get lost in some labyrinthine ruins. Its translucent amber* body reveals some kind of artifact inside, ancient tech possibly developed by atlanteans and designed to react to near orichalcum traces like a compass would do with iron.

● 90 mm x 50 mm / 3 ½" x 2"
● *well, it is not amber but pressure cast yellow-dyed clear resin.
● metal casted mysterious atlantean greeblie trapped inside.

String shown not final.
