I love stones! I had to research different ones for the second book in my series, and I enjoyed it (usually I hate research, haha) I learned there's all kinds of interesting qualities attached to them, such as healing and peace. I'm not big on anything hokey, but I believe that naturally occurring things of the earth can certainly house beneficial properties.
I didn't know you lived in South Africa, I love how my friends on steemit are all over the globe!
