As a child of the '60's, what else could I call this necklace? (See the book below if you are not a child of the '60's.) I put lightning on the back to recall the Tower in the Tarot. Leigh Becker of Eidos cut this magnificent Agua Nueva agate geode. The deposit is in Chihuahua, Mexico less than 40 miles from the famous Laguna agate deposits.
