It is a popular Catholic sacramental and holds a special significance for many believers.The Miraculous Medal was designed by French engraver Adrien Vachette in 1830, following a vision experienced by a young novice nun named Catherine Labouré. According to her account, the Virgin Mary appeared to her and requested the creation of a medal with specific imagery and inscriptions. The design includes an image of Mary standing on a globe, with rays of light emanating from her hands and the words "O Mary, conceived without sin, pray for us who have recourse to thee" encircling her.

Many individuals claim to have experienced physical or spiritual healing, conversion of heart, protection from harm, or other blessings after wearing or praying with the medal.

The Miraculous Medal is often worn as a necklace or a bracelet, and some people carry it in their pockets or keep it in their homes.
