From A. Wagner: I’m absolutely in love with agate slices. My great aunt had a huge collection of them in a beautiful display case and I spent hours looking at them as a kid. Yes, hours. I was a little quirky, yes, but the beautiful swirls of color and speckles of glimmering crystals were mesmerizing. Now that they’re everywhere and mostly as coasters, I want them! All of them! But that would be crazy and also really, really expensive.
