Circles have been used as symbols for centuries to represent unity, wholeness, and infinity. They are also known as protective symbols and are universally used to represent the sun and moon, and sometimes spirituality. In alchemical symbolism, the triangle symbolizes the three planes of human existence- physical, mental, and astral. The number three represents the magic of manifestation and embodies thoughts, emotions, and actions. Add a touch of symbolism to your jewelry collection with our sterling silver 15mm logo charm.
