16th Century Tudor Priest's Rosary Ring. Extremely Rare Rosary Ring. The Rosary was brought to Europe by the Crusaders, and consists of a number of groups of beads. Strictly, the full rosary consisted of three Chaplets, each consisting of 5 Decades and 5 Paternosters. Another variation of the Rosary is the Decade Ring or Rosary Ring. The ring would have ten projections as Aves around the shank, with the bezel being a Paternoster. These rings became more popular in the 16th Century as religious persecution grew, and are still popular in Spain
