1. My piece of rose quartz. It is not polished, so it is quite sharp, but it catches the light wonderfully. I like to carry it in my pocket because it's large enough to make its presence felt.

3. Grating nutmeg into mashed potato. I like cooking with nutmeg because when you grate it, the speckled inside is revealed.
