Danburite

  

 

  

Danburite on talc matrix. These are the only BLUE danburite crystals that I have ever seen from any locality. Truly the crystals themselves are colourless, but are included by a rare amphibole called magnesioriebeckite, for which this is the type locality. An interesting historical note about this locality: Supposedly the mineral was first discovered in the tomb of a "cacique" (a native Indian chief) where they had been placed as jewels to signify that he was rich. The find of these crystals was made near there.
