Manhattan Project Shield Window Fragment - SOLD 132g B surfite Note: The 1908 Cross Section

Note: The 1908 Cross Section specimen is a limited-time collector's item

the element's utterly unique colors and shape continue to captivate the mind

Each specimen ships in its own glass-topped riker display case that measures 4"x3"x1"

This is normal and occurs due to the fragmented nature of an airburst impact

which also wiped out the dinosaurs
