My son had a school field trip yesterday, where he got to "mine" gemstones and learn about them. He came home with a bag full of assorted blue, green, red, and purple gems. He dumped them out on the kitchen table. "Mama, which is your favorite?"
I took a look and picked up an aqua-colored stone. "This one."
"Do you know which one is my favorite?"
"No, Bubba. Which one is your favorite?"
He picked up a topaz-colored rock with brown stripes. "Take a look at this one." He held it in front of my face and slowly moved it across my line of vision. The stone was like a holographic image. As he moved it, the pattern on the surface of the stone seemed to change. "It's a tiger's eye," he explained. "Do you know why I like it?"
"Because it's fancy?" I asked.
He nodded. "And because I can use it to hypnotize you!"
