Replica of the Pym Particle Disks used in Marvel's Ant-Man - http://marvelcinematicuniverse.wikia.com/wiki/Pym_Particles_Disks
Since the discs are two sided, a full prop will require 2 gems and 2 prints of the ring, one mirrored. I printed mine in silver PLA for the ring, and red/blue translucent filament for the gems.
