In psychology and philosophy, the circular shape of the ring (in Japanese “yubiwa”) is often interpreted as a symbol of completeness and totality, embodying a sense of balance and perfection. It also represents the idea of union and connection, symbolizing the continuous bond between two elements or people. Thanksto its simplicity and versatility, the ring as a circular form manages to combineaesthetics, symbolism, and functionality, reflecting fundamental aspects of daily life and human culture.
