A page marker or a popular bookmarker like a tneth of rosary. Made of a combination of semi-precious stone and Czech crystal and metal components. There is a metal cross and a Miraculous Medal on the marker.
"Dark jewels mean mercy that people do not beg for. The picture then turns. In the middle is the capital letter 'M'. In the letter 'M' is a cross implanted. Beneath the letter are two hearts: one wrapped in a crown of thorns and the other pierced with a sword. it has to be the other side of the medal. I thought that maybe there was no need for an inscription. I felt the answer: 'The letter M and two hearts speak enough.' I heard a voice say: 'Let's make a medal according to this pattern. Everyone who is blessed will wear it about the neck will receive many and great graces. Immeasurable graces will also be received by those who wear the medal with confidence '", wrote St. Catherine Labouré in her diary about the event that took place on this day in 1830.
