Publisher Marketing: You don't have to have extensive background in magic to make use of any stone. In fact, you don't have to know about magic at all. If you are facing a difficult situation and feel you need protection and courage, wear garnets. Do you want to attract a lover? Use rose quartz or ruby. Are you troubled by negative vibrations? Wear, carry, or keep near you black onyx or obsidian.
