In 1830, Our Lady appeared three times to St. Catherine Laboure. During an apparition, Catherine was instructed to commission a medal depicting the images revealed to her. The front of this stunning 14 karat gold Miraculous Medal shows the Blessed Mother with the words 'O Mary conceived without sin, pray for us who have recourse to thee.' The 14 karat gold medal is 3/4 of an inch. The backside of the medal has the Virgin's monogram, the letter 'M' with a cross and 12 stars, the Sacred Heart of Jesus and the Immaculate Heart of Mary. This beautiful 14 karat gold Miraculous Medal comes on an 18 inch gold filled chain with clasp. The entire necklace comes packaged in a velvet texture hinged jewelry box.
