Tektites are used for wisdom, knowledge, and to help withstand mental or emotional "stumbling." They are also used to diminish or overcome challenges with mental processes. Psychically they are used for extraterrestrial communication, astral travel, and lucid dreaming. Tektites are also used to strengthen one's energy field. Note that healing crystal meanings are spiritual supports to healing and are not prescriptions or healthcare information.
Moldavite is a type of tektite.
