CRYSTAL CRESCENT MOON SUPER MINI II necklace18K gold stainless steel set with cubic zirconia necklace As a source of light in the darkness, the moon can symbolize illumination, insight, and guidance. The gentle, reflective light of the moon represents the knowledge we find within ourselves. While the sun produces its own illumination during the day, the moon reflects light we otherwise wouldn't see at night. That gentler glow symbolizes intuitive knowledge and gut feelings that come from within.
