GEOLOGICAL INFORMATION
Colombianite is natural volcanic glass from Colombia, also known as Piedra de Rayo, or “lightning stone.” Commonly called a pseudotektite because of its resemblance to tektites, scientific research supports a terrestrial volcanic origin.
Like obsidian, it formed as molten volcanic material cooled rapidly, preventing a crystalline structure from developing. Its glassy composition allows strong light to pass through portions of the specimen, revealing brown and amber tones that are less apparent in ordinary lighting. Its textured surface reflects natural weathering over time.
