Thallium APEX Mineral

Thallium (Tl #81) is the next element on the periodic table for my APEX mineral collection.  

Wikipedia Thallium
Thallium Minerals - There are lots of Thallium 
minerals.  
Lorandite (TlAsS2) (Thallium Arsenic Sulfide) with 60% Thallium is the best APEX Mineral choice.    
Thallium is fairly abundant on Earth.  However, there aren't good exploitable deposits.  It is recovered as a waste product from other mining processes.
Thallium was unknown until modern times.
Thallium is primarily used in the electronics industry.  Thallium Sulfide electrical conductivity changes with exposure to infrared light therefore making this compound useful in photoresistors.

Thallium does NOT make a good name for a perfume.
Thallium and most of its compounds are extremely toxic and must be handled with care.
