A pentacle is a symbolic piece of jewelry that symbolizes Pagan. A Pagan wears a pentacle just as Christians might wear a cross or Jews might wear a star. The meaning of the symbol is that the five points on the star represent the spirit or self, and the four elements of air, water, earth, and fire.
Wiccan pentacles are circumscribed by a circle. A large pentacle can be used as an altar or as a sacred space of its own. Wiccans also very often wear a pentacle necklace as a symbol of their faith. Pentacles are commonly used for protection and in Pagan rituals.
The spirit is the top point of the pentacle which represents the god and goddess who we love. Air is the air that we breathe. Water is the liquid we need to survive. Fire is the warmth in our body. Earth is the source of food. The spirit and the four elements are often colored. The spirit is purple or silver, the air is yellow, the water is blue, earth is green and fire is red.
Wiccans use the pentacle symbol as an amulet in magical evocations. A metal pentacle might by the symbol of a specific spirit, energy or magic that is evoked upon. Wiccans commonly use the pentacle as a magical tool to summon certain energies or spirits. Pentacle jewelry is beautiful and you can often find gorgeous metal hand-crafted pentacles adorned with silver and gemstones.
