Thanks!
Photo #97
Shown: A Hypomelanistic Ball Python with Quartz (grouped up the blue-ish pieces together) and plain colored Quartzite. Quartzite is a composite of Sandstone incorporated into Quartz.
I did not know what Quartzite was and while collecting I was unable to tell the difference between Yellow Quartz with a weathered rind (Photo #92) vs. Quartzite...I ended up tumbling a bunch of plain colored stones lol.
As for the quartz pieces: they had some gold colored streaks on the surface pre-tumble (shown below). I was hoping the metallic color was pyrite....it was not...disappeared in tumble.
I showed this photo to my 'rock buddies' and they said the gold color was not metal, but, a type of organic matter...disappointment...
