Garnierite is often called Green Moonstone, though it isn't a moonstone and different sources argue about what exactly it is. It is, however, a very gentle stone. In my opinion it has a similar energy to rose quartz, though the green gives it a creative, natury vibe. It would be good for working with the heart chakra or resting on the body during meditation. It is about 4 1/2" x 4" x 1"
