Moldavite is a forest green, olive green or blue greenish vitreous silica projectile rock formed by a meteorite impact probably in southern Germany that occurred about 15 million years ago. It is a type of tektite.
czech moldavites (tektite) are in many varieties of green..They colour, shape and surface depends on localities...very rare moldavites are in brown colour (muong nong) or two colored (brown + green). The best moldavites are from Besednice, Chlum, Ločenice , Dobrkovská Lhota and Brusná - Czech Republic. Do not buy any moldavite from China!!!
