This moldavite tectite is from Besednice i South Bohemia, Bohemia, Czech Republic. The tectites from Besednice are arguably the finest known. They were created approximately 14.7 million years ago when a giant meteorite impacted the earth near modern day Nordinger Res. The liquefied crust that was caused by the impact was ejected into the atmosphere and then fell back to earth in a broad pattern extending hundreds of square miles. The Besednice area contains unique clay deposits that helped create the exceptional spiney splash-like surfaces on the moldavite found there. As the molten material fell splatter patterns and other aerodynamic surfaces were created on the pieces as they cooled and impacted the clay. They are similar to volcanic glass or obsidian in make up. This specimen weighs 2 grams and it measures 1 1/8 x 5/8 x 3/8 inches (including the curved surface) or 28 x 16 x 10 mm.
