MOLDAVITE is a member of the tektite family, with a hardness of 5.5 to 6. Tektites are a group of natural glass consisting of a very high silica content and a very low water content, that form as a result of hyper-velocity meteor impacts that melt the surrounding rock. The formation of moldavite coincides with an impact of approximately 14.8 million years ago, which formed the Bohemian plateau in the Czech Republic. This region is the only source for moldavite, although tektites of other types are found all over the world. Evidence from archeological digs show that the Neolithic people of eastern Europe wore moldavite and used it for tools as far back as 25,000 years ago.
