The Ringstone Symbol
The purpose of the symbol that appears on Baha’i ringstones and other Baha’i identity jewellery serves as a visual reminder of God’s purpose for man, and for Baha’is in particular. The top horizontal bar represents the world of God, the Creator. The middle bar symbolizes the world of His Manifestations, unadorned. The bottom bar represents the world of man.
The vertical line joins the three horizontal bars together in the same way that the Divine Messengers of God form the link between the world of God and the world of man. The twin five-pointed stars on either side of the design represent the Bab and Baha’u'llah, the twin Messengers of God for this age. The ringstone symbol was designed by Abdu’l-Baha.
The Greatest Name
The Greatest Name, or more fully, the calligraphy of the Greatest Name of God, is a calligraphed Arabic rendering of "Yá Bahá'ul 'Abhá"
("O Glory of the Most Glorious!"). It was originally done by the eminent early Bahá'í calligrapher Mishkin Qalam, and later adopted by Bahá'ís everywhere
Nine-pointed star
A simple nine-pointed star is generally used by Bahá'ís as a symbol of their Faith. The number nine has significance in the Bahá'í Revelation. Nine years after the announcement of the Báb in Shiraz, Bahá'u'lláh received the intimation of His mission in the dungeon in Teheran.
Nine, as the highest single-digit number, symbolizes completeness. Since the Bahá'í Faith claims to be the fulfilment of the expectations of all prior religions, this symbol, as used for example in nine-sided Bahá'í temples, reflects that sense of fulfilment and completeness.
