I. The Metaphysical Reading
How the stone has been held.
Colombianite is worked with as a stone of ancestral protection, carried in ceremony and used as a scrying medium in practices descending from the Muisca. Practitioners hold it as a stone that keeps a person on a chosen path when the outer noise is loud.

II. The Scientific Reading
What the lattice actually does.
Colombianite is a dark, glassy volcanic silica-rich natural glass found in Colombia's Cauca Valley whose origin is debated: it has been treated by some authors as a tektite-like impact glass, but the majority of recent geochemistry points to a terrestrial pyroclastic source (obsidian-like) rather than a meteoritic one. Its high silica content and rapid quenching give it the classic conchoidal fracture of natural glass.
