Milagros and Exvotos charms, are tangible expressions of faith, intricately intertwine belief and tradition across Europe and the Americas. Originating in Europe, particularly prevalent in Spain, Italy, Portugal, Greece and France, Exvotos initially took the form of larger plaques. These votive offerings, crafted from metals like bronze or silver, symbolized gratitude or devotion to saints or deities, often depicting the healed body part or resolved situation. The term "Exvoto," derived from Latin meaning "from the vow," encapsulates the solemn promise fulfilled through these offerings.

As these traditions traversed the Atlantic to the shores of Mexico and Latin America, Exvotos transformed into Milagros, taking on a smaller, more portable form. The word "Milagro" itself carries deep significance, translating to "miracle" in Spanish. These miniature charms became symbols of hope, carried by the faithful seeking solace and divine intervention in times of uncertainty.
