The 1950s: a time of enthusiasm and a desire to build. These were two qualities that Mario Sessa certainly possessed, and on December 19, 1955, he opened a small business dedicated to the repair and sale of alarm clocks and watches.
His professionalism, expertise, and passion for his work were quickly recognized by his customers, allowing the business to grow. This also led to the establishment of a workshop, where Mario passes on the culture and knowledge of the watchmaking craft to young apprentices.
In 1966, his wife Marisa joined the business, and in 1974, the store expanded with the opening of a second floor. During those same years, Mario earned the title of Diamond Expert, a testament to his ongoing commitment to professional development and his deep knowledge of the jewelry industry.
Upon his sudden passing in 1977, his children Fabrizio and Rossana carried on his legacy and continued the family business with the same enthusiasm and dedication, strengthening over time the relationship of trust they had built with their customers.
In 1994, following Marisa’s passing, the jewelry store continued on its path thanks to the family’s commitment.
The year 2007 marked another important milestone: Daniela, Fabrizio’s wife, took over the business from Rossana. That same year, the City of Milan recognized Gioielleria Mario Sessa as a Historic Shop. In 2008, the business also received the prestigious “Historic Store ” designation from the Lombardy Region.
Training has always been one of the company’s core values.
In 2012, Fabrizio Sessa earned his Diamond Expert certification from CISGEM, and that same year, the Milan Chamber of Commerce awarded Gioielleria Mario Sessa the prestigious Milano Produttiva Award.
In June 2026, Valentina Sessa officially joined the company, marking the beginning of the family’s third generation. She, too, chose to train at CISGEM, delving deeper into the study of diamonds and colored gemstones to acquire new skills and carry on a legacy that began more than seventy years ago.
Today, Mario Sessa Jewelry is the result of three generations united by the same values: passion, expertise, integrity, and trust.
A family story, serving its customers since 1955.
