Rocks

Rock #1- its not grainy the rock is built of little chunks of (?) quartz. Mostly brownish, with a silver shiny edge.

Taken with flash on to show the shiny.

Rock #2. White quartz with some kind of black mineral in it, much of the quartz around here has this black in it, would love to know what it is.

Rock #3. If you hold this too long a white grainy substance comes off in your hands. Its very light.

Same rock from the other side. All of these are under 3", I take home ones that seem neat to clean them up and if I really like it I go back for the big ones. These were all found at Picket Post Mountain in Pinal County, Az.
