Colombianite 7.69 g 21x20mm
Colombianite is back at IVC! These Pseudotektites come from Colombia, they are called lightening stones by native tribes. They are ancient volcanic obsidian.
These appear brown to lilac in color when held to different light sources - We shot the back lit photos with LED.
These pseudotektites are the final survivors of their ancestral volcanic parents in the geologic Garden of Eden. As the strongest bits in the hearts of boulders, they are something of a crowning gem (—and the gemmy transparent lilac ones do indeed facet into spectacular jewels!). Hold one and marvel. It is not a tektite. It doesn’t need to be. It is a stone with its own amazing story. It is one of the final generation of its kind before ultimate extinction. A grandfather boulder-heart! from Meteorite-Times magazine.
