This unique chaplet of St Bridget of Sweden, also known as the Brigittine rosary or Bridgettine rosary, consists of 6 decades rather than the traditional 5, with both silver and gold beads in between each decade. On the gold beads, the Apostle's Creed is said; on the silver beads the Our Father, and on the blue beads the Hail Mary. The 63 total beads are said to represent the 63 years of the life of the Blessed Mother. Here is one link with more details to the rosary: http://fountainofelias.blogspot.com/2009/05/st-bridget-of-sweden.html. Also very popular are the 15 prayers that Jesus gave to St. Bridget, which have wonderful indulgences attached to them and approved by Pope Pius IX.
