I love these little hand-made terra cotta chakra aromatherapy discs from Soul Candy by Amy Logan Life and Art. Put a drop or two of your favorite essential oil blend on the white part, and it holds the scent. You can place them around your house, use them to meditate, or carry them in your pocket. The scent lingers and if you place them near you (such as at your desk), you'll notice your favorite aroma throughout the day.
The stones are $39 for a set (on sale for $25 now), which includes 7 discs stamped with each of the seven chakras and glazed a corresponding color. It's a cute, creative, and portable way to have your favorite aromatherapy blend with you wherever you go.
