The ringstone symbol was designed by `Abdu'l-Bahá, Bahá'u'lláh's son and successor, and as its name implies, is the most common symbol found on rings worn by Bahá'ís, but it is also used on necklaces, book covers, and paintings
It consists of two stars (haykal) interspersed with a stylized Bahá’. The lower line is said to represent humanity and the world of creation, the upper line the world of God, and the middle line represents the special station of Manifestation of God and the world of revelation; the vertical line is the Primal Will or Holy Spirit proceeding from God through the Manifestations to humanity. The position of Manifestation of God in this symbol is said to be the linking point to God. The two stars or haykals represent Bahá'u'lláh and the Báb.
