This is the Silver Ore I spoke of from our cross-country trip. It's from the Silver Valley near the Sunshine Mint in Idaho. This is a piece of high-grade Silver Ore. From the pictures it's not nearly as impressive as in person.
Raw Silver
These are silver crystal structures. They grow like this naturally but do require some cleaning from the host rock. I'm pretty impressed with these close-ups my camera took. Much better detail than with the naked eye.
I tried to blow the dust out but it wasn't happening without possibly damaging the crystals. Here is the size of them for comparison.
