A beautiful Petrified Ice Cube is attached to a business size card. These beautiful calcite crystals are fluorescent! A small amount of manganese is enough to make it glow red under UV light. Each Petrified Ice Cube has the classic rhombohedra form. Extremely sharp edges and terminations. Good clarity allows the "double refraction" effect to be easily seen. Give one to a friend!
