Tektites resemble tear-shaped pieces of obsidian but occur far from any volcanoes. they differ in shape, pattern and composition from obsidian, or from any moon rocks. One theory is that they are “glass” meteorites composed of pure silica. The exact nature and origin are, however, still under dispute. They are generally found in small, black, pear-shaped or cylindrical pieces, rounded on the ends and with bubble-like indentations. Tektites have powerful energies – and encourage the accumulation of knowledge and increase insight and comprehension. They increase the memory of desirable events and inhibit the recollections of unfortunate experiences without losing the message of the lessons to be learnt therefrom.
