This stone is called variscite. Out of the thousands and thousands of stones I touched at the Tucson Gem and Mineral show, this one had to come back to the woods with me. I've seen, and even have, other variscite stones. But not this one.
The piece is almost 2 inches tall by about 1 inch wide. The stones are set using sterling and fine silver. The pendant is suspended on an 18" sterling silver snake chain.
“It would seem from this fact, that man is naturally a wild animal, and that when taken from the woods, he is never happy in his natural state, 'till he returns to them again.” --Benjamin Rush, A Memorial Containing Travels Through Life or Sundry Incidents in the Life of Dr Benjamin Rush
