HUGE whole 3.7 lb POLYHEDROID… Polyhedral Agate… Paraiba, Brazil… UV Reactive For Sale

Excellent condition, see pictures. Everywhere I tested I got a UV reaction it should be an interesting piece once opened up.

PS, if you notice the first two pictures are the same pictures one with the black light behind the agate and one in front of the agate. All of the pictures with UV reactions are backlit so the flourescense is coming from inside not the surface.
