Last Thursday, I took a stroll in the Scottsdale Arts District, viewing fabulous galleries and tasting delicious food during the weekly ArtWalk event. I ventured into a lovely place called Touchstone Gallery on Marshall Way. It had not just art but also great jewelry, home décor, and unbelievable minerals and fossils. You can see beautiful amethyst geodes, exquisitely preserved woolly mammoth tusks, and petrified wood.
