Robert mines for Topaz crystals in the Tarryall Mtns which are near Lake George, Colorado.  He faceted one of those crystals into this 10mm round gem weighing 4.2 carats.  We then set the gem in a Sterling Silver Pendant.  
 
Topaz is a November Birthstone.
 
For this Pendant, we recommend an 18” Light Curb Sterling Silver Chain, #1165.
