Uses & applications

Used primarily in lapidary arts, wire-wrapped jewelry, metaphysical crystal healing, and scientific studies of impact events.

Geological facts

Tektites are not meteorites themselves, but rather Earth rocks melted by extraterrestrial impacts. Their name derives from the Greek word tektos, meaning melted.
