Tellurium APEX Mineral

Tellurium (Te #52) is the next element on the periodic table for my APEX mineral collection.   

Wikipedia Tellurium
Tellurium Minerals - There are many Tellurium minerals.  
Tellurite (TeO2)[Tellurium Oxide] with 80% Tellerium is the obvious APEX Mineral.  Tellurium also forms the only minerals with Gold.  
Tellurium is rare on Earth.  During the formation of Earth, the highly volatile Tellurium Hydride (and also Selenium Hydride) escaped the gaseous nebula.
Tellurium and its compounds were not known historically.
Tellurium is primarily used in Iron, Copper and Lead alloys. 
Tellurium has no biological function in animals.  In fungi it can replace Sulfur and Selenium in some amino acids.
