Alex's passion for jewels flows in splendid pieces entirely hand-crafted according to the best goldsmith Italian tradition. This piece will arrive at your door beautifully gift wrapped in Alex Jona boxes, put inside an elegant pouch or jewel box. OUR STORY Walking past number eight of Via Bogino, Palazzo Balbo di Vinadio, a baroque building built in 1690 in Torino, you would little suspect that its grand façade conceals a 3300 sq ft. chic gallery that more than a shop resembles to a 18th century noble town house containing a remarkable collection of design jewelry, antique silver and object d’art. This is the story of a passion which started back in 1961 when Giorgio Jona, enthusiast, passionate collector of antiques decided to leave the stock exchange career to start his own business, dealing in antique silver, antique oriental art and gemstones for the creation of fine jewelry. The company has grown since then, also thanks to the shared passion for the business by Giorgio's son, Alex, who felt the need to create jewelry which may be worn in every occasion. Today Alex Jona is home to highly skilled craft people and support staff with the clear ambition to keep on growing. Alex travels the world to discover extraordinary precious stones, pearls and diamonds with which he personally designs exquisite pieces of jewelry.
