Pyrites

Tiny Tuesday challenge was a mineral.  The easy part ---  my husband the resident gardener cannot pass by a rock store on any of our travels and not buy an interesting mineral or fossil so I had much to choose from.   The hard part was picking something and taking an interesting photo.  This was the winner of the day.  A pyrite,or often called fools gold  the cube is natural and perfectly created, shiny with a surface no bigger than your fingernail.
