Purple Czech crystal beads, with momento mori skull Our Father beads. Memento Mori is a very ancient Catholic reminder of our mortality. Many saints including Teresa of Avila and John of the cross famously kept a skull on their desks, so as to remind them that everything is passing in this life, and to keep things in the perspective of eternity.
Perfect for Lent, and for praying for the souls in purgatory. The center piece is the Holy Eucharist, reminding us to have Mass said for our deceased loved ones.
