HUGE CAST AMMONITE- GLOW IN THE DARKThese are translucent urethane casts taken from a real fossil ammonite! These casts glow bright aqua in the dark and have flashy bits of opal like material embedded in them. The result is a truly beautiful and odd object that can be displayed on a stand or maybe used as a dangly sun catcher in front of a window! Or you could be the Flavor Flav of fossil collectors and wear it around your neck! I won't judge. These casts measure 5. 5" at the widest.
