Opis:
Tektite (Var.: en:Moldavite)
Locality: Moravia (Mähren; Maehren), Czech Republic (Locality at mindat.org)
Size: 8.8 x 6.8 x 6.3 cm.
A gem-quality, 3.2 cm, typically discoidal, furrowed, deep bottle-green moldavite tektite set in rounded pebble conglomerate from the Type Locality in the Moldau River region of the Czech Republic. Back-lighting and front-lighting shows the gemminess of the piece. Moldavites are green natural glass, thought to be formed from meteorite impact melting the local rocks. Matrix specimens are very rare and are rarely available. This matrix is friable and so it is something to handle with care, but it is the real matrix this was found in, and as such presents this gem rough material in context.
