A 63.8g sample of Titanium metal in the form of a crystal bar.  Purity is 99.99%.  Crystal bars like these were produced in the former Soviet Union by the crystal bar process aka van Arkel–de Boer process which results in extremely pure metal.  These are rarely offered for sale and are becoming extremely hard to find.  This piece is truly amazing and has a beautiful crystalline surface.  This is a unique form of Ti metal not commonly found.  I only have one piece this size.
