Robert mines for White Topaz crystals in the Tarryall Mtns which are near Lake George, Colorado.  He faceted two of those crystals into matching 7x7mm trillion shaped gem 
weighing 1.7 carats each.  We then set the gems in a Sterling Silver Post Earrings.  
 
Topaz is one of the November Birthstones.
