Moldavite formed as a tektite from a fiery meteorite crash near the Moldau River in Bohemia 15 million years ago. It has a pitted glass-like appearance with a green hue. True to its celestial roots, it is called "Tears of Heaven" and the only extraterrestrial gemstone known. It has a strong "feel" so some people need to gradually adjust to its energy. When needed, it can trigger emotional release such as laughter or tears. One of the best crystals to use when change is needed in life, it is known as a stone of evolution and spiritual transformation. Overall, Moldavite is highly protective and oriented to manifestation, such as good fortune, fertility and growth. Ideally worn as jewelry or talisman.
