The Miraculous Medal is a devotion to the Virgin Mary called the "Miraculous" Medal for the many miracles associated with those that wear it. It is one of my favorite medals to wear.
The Miraculous Medal came to the world through an Apparition of the Virgin Mary to Catherine Labouré in Paris, France in 1830. In Mary's second apparition, she asked that "a medal should be struck in this image. The people wearing it will receive my indulgence and those who piously say this short prayer will enjoy my very special protection".
One of the most famous conversions due to the miraculous medal was that of Alphonse Ratisbonne, an anti-Catholic Jewish banker. He received a vision of Our Lady of the Miraculous Medal. After his conversion, he became a priest and worked for the conversion of the Jewish people.

English Translation of the Traditional Prayer Said by the Priest to Bless the Miraculous Medal:
The priest who is to bless the sacred medal of the Immaculate Conception, vested in surplice and white stole, says:
P: Our help is in the name of the Lord.
All: Who made heaven and earth.
P: The Lord be with you.
All: May He also be with you.
Let us pray.
Almighty and merciful God, who by the many appearances on earth of
the Immaculate Virgin Mary were pleased to work miracles again and
again for the salvation of souls; kindly pour out your blessing + on
this medal, so that all who devoutly wear it and reverence it may
experience the patronage of Mary Immaculate and obtain mercy from you;
through Christ our Lord.
All: Amen.
The priest sprinkles the medal with holy water, and presents it to the person, saying:
Take this holy medal; wear it with faith, and handle it with due
devotion, so that the holy and immaculate Queen of heaven may protect
and defend you. And as she is ever ready to renew her wondrous acts of
kindness, may she obtain for you in her mercy whatever you humbly ask of
God, so that both in life and in death you may rest happily in her
motherly embrace.
All: Amen.
The priest continues:
Lord, have mercy. Christ, have mercy. Lord, have mercy. Our Father (the rest inaudibly)
P: And lead us not into temptation.
All: But deliver us from evil.
P: Queen conceived without original sin.
All: Pray for us.
P: Lord, heed my prayer.
All: And let my cry be heard by you.
P: The Lord be with you.
All: May He also be with you.
Let us pray.
Lord Jesus Christ, who willed that your Mother, the blessed Virgin
Mary conceived without sin, should become illustrious through countless
miracles; grant that we who ever seek her patronage may finally possess
everlasting joys. We ask this of you who live and reign forever and
ever.
All: Amen.
