Platinum minerals which are mostly metal alloys.  
Platinum nuggets are rare and almost pure Platinum.
Platinum is one of the rarest elements in the Earth's crust and it is the least reactive metal.  For this reason the little Platinum that exists can sometimes be found as almost pure nuggets.  Platinum is slightly harder than Iron.  Only 300 tons of Platinum are produced each year.

Platinum is one of the six Platinum Group Metals.  These are precious metals which have similar physical and chemical properties, and tend to occur together in the same mineral deposits.
