I'm a sucker for all manner of little wooden boxes, and this is a sweet and very little one. Inside is a shiny rock sample affixed to a little metal base. I am not sure exactly what the rock is, possibly Pyrargyrite (??), or whether this box was made specifically to house it, but I'm selling as found and like the combo of tiny treasures!
Box measures 1 1/4" tall x 1" across.
