Blessed Prayer Beads is a quest-reward trinket from a Priest-only quest line involving Sunken Temple. It is argued to be the best reward option from that quest (even for Shadow Priests), as the other reward choices ( and ) are easily replaced by gear from instances as low as Stratholme and Scholomance.
Effective Spell Power
Assuming this trinket were activated every cooldown, it would grant:
101 * 20 / 120 = 101 * 1 / 6 = 101 / 6 = 16.83 Spell Power
