Each piece of jewelry is crafted from genuine circulated coins, transforming them into limited edition treasures.

The scratches and marks on these coins share stories of their past, preserving the journey they have taken through time and bestowing a unique authenticity to every medallion. Each imperfection echoes a different tale, making every piece not just a beautiful accessory, but a heartfelt connection to history and personal significance.

As a family business, our team is composed of a dedicated numismatist and a skilled jeweler, working together to create what we affectionately call our "heart business." We are truly passionate about our craft, and we’re eager to share that love with each of you. "Prometto," meaning "I promise" in Italian, embodies our commitment to honoring the rich tapestry of history and the inspiring art of the past.

This name also serves as both a promise and a dedication to crafting pieces that are authentic and carry enduring value - for us, for history, and for generations to come. These guiding principles motivate us to design exquisite contemporary pieces that effortlessly blend the past with the present, allowing each individual to carry a meaningful connection to history close to their heart.
