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 is 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 releases 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.
A rough version of crystal is usually cut from a much larger piece of mined material that is too large or heavy to be used by a person. Rough chunks such as calcites are often acid washed to subtly smooth out rough edges that may cause cuts or injury and to prevent further flaking or breakage.
