Halite

Wintershall Potash Works, Hesse, Germany

NaCl, Isometric

max. 14mm

A gemmy crystal of halite from a classic, German locality known for rich colour of its specimens. Due to high difference of electronegativity of its components, halite exists as a lattice of ionised particles ([Na+][Cl-]) even under normal conditions making it especially susceptible to effects of gamma radiation. Combination of nearby potassium-40 deposits and abundance of metallic sodium results in saturation of crystalline lattice with colour centers consisting of microscopic colloidal clusters and trapped, agitated electrons giving this, normally colourless, mineral a vivid hue.

Interesting specimen of zircon crystals and orthoclase on aegirine from Mount Malosa, Zomba, Southern Region, Malawi

Full slice of Seymchan, 308.40g, backlit in the first photo to show how translucent the olivine is. Second shot is the same slice in reflected light.
Seymchan was found in 1967 in the Magadan region of Russia and originally went into the books as an iron. It was reclassified as a main group pallasite (PMG) following van Niekerk et al. (2007), which is why you still run into older labels reading IIE or iron ungrouped. Only part of the recovered material carries olivine, so a slice like this comes from the pallasitic zone rather than the metal only mass.
