Phosphorus APEX Mineral

Phosphorus (P #15) is the next element on the periodic table for my APEX mineral collection.  
Wikipedia Phosphorus
Phosphorus Minerals - 
The are not many Phosphorus minerals that fit my APEX mineral definition.
Beryllonite at 24% Phosphorus is easily the best APEX mineral.  
Phosphorus exists in several forms (allotropes) that exhibit strikingly different properties even though each is pure Phosphorus. 

In the 19th century, Phosphorus sources were organic [bone ash and guano].  Inorganic phosphate rock [tri-calcium phosphate] is the chief commercial source of this element. Pure Phosphorus is also produced and often transported in molten form. Some major accidents have occurred during transportation including train derailments.
Phosphorus was the first element to be discovered that was not known since ancient times. 
Most Phosphorus is used in fertilizers.
Phosphorus is critical for all forms of life.  It is found in DNA, RNA, ATP (energy transport), Lipids (cell walls), and bones.
