Runcinium

Runcinium is a mineral discovered by Professor Sadovnycha on his Historic Expedition to the Earth's Core aboard his burrowing earthship, Corepheus. Formed at the Profound Pressures of the Core, runcinium develops a "folded" crystalline structure with properties unknown at the Surface. Light is refracted by the crystal layers to produce a beautiful, shimmering, irridescent effect impossible to convey through still images.
When stress is applied to a runcinium crystal, the movement of the layers against each other can generate an intense Static Electrical charge which in turn causes the molecules to oscillate in harmony, allowing it to maintain its form even under the incredible pressures of geologic movements. This effect is most pronounced in crystals of Runcite, the purest form of runcinium, which forms elongated crystals highly resistant to fracture.
Because of runcinium's unique molecular structure, it becomes highly unstable at surface pressures. Without proper containment, a runcinium sample would be torn apart at a molecular level before it ever reached the surface. And once brought to the surface in a pressurised tank, even a small chunk of runcinium would Explode with Incredible Power if its containment was ever breached. 
However, a properly designed Runcinium Containment Device can not only prevent a catastrophic blast, but also allow the crystalline structure to decay slowly in a controlled manner, drawing off incredible electrical power almost indefinitely.
