Moldavite glasses formed 15 million years ago during the impact of a giant meteorite in present-day Nördlinger Ries. Splatters of rocks that were melted by the impact cooled and most fell in south Bohemia - traversed by Vltava river, in German: Moldau, hence its name. They are a type of tektite and impactite. The specimen offered in this auction is a wonderfully shaped moldavite that can be enjoyed with light on the back or naturally. Certificate of authenticity included. IMCA 5591. Packages are usually sent the morning after the auction. Shipping is combined in all my listings - if you win multiple items, only one shipping cost is paid. Do not miss this opportunity!
