Exogenic Fulgurite   From lightning strike that occurred in Oswego, New York on August 25, 2008.  Collected by Jeffery Shallit of Kitchener, Ontario and nephew and sons (Joseph, Jonah and Arlo).  Reference Rocks & Minerals magazine, May June 2011 issue, vol. 86, no. 3, p. 264-70.  This exceptionally large tadpole shaped piece is composed of a large flagellated droplet with several tapered spines (the two smaller ones not being terminated) measuring 6.4 x 1.7 x 1 cm.  The topside is all glassy and the bottom is, as well, but also has tiny grains attached due to its landing on the soil before being completely solidified.  The tip of the piece has a tiny grain of stone embedded in it.  This is a very aesthetic and interesting piece.  $280
