Alex Jona Dome Rings

When Alex Jona joined the Italian jewelry purveyor that his father, Giorgio Jona, had founded in 1961, the Jona brand began to offer elegant bracelets, cufflinks, necklaces and other accessories subdued enough for daily wear yet visually splendid and skillfully handcrafted using precious metals and stones.

Tucked in a 1690 Baroque building on Torino’s Palazzo Balbo di Vinadio is a 3,000-square-foot showroom. This is the headquarters of Jona, home to luxury jewelry designs that are complex, yet often understated. For example, a slender pair of yellow tourmaline drop earrings set into 18-carat gold has a juxtaposition creating just the slightest contrast, which might be noticed only upon close inspection.

Alex travels frequently, and precious stones collected from around the world are a common fixture in Jona jewelry — he personally designs pieces with stones like lapis lazuli shaped into eye-like cufflinks, sapphires caged in 14-carat-gold rings and quartz crystals stacked into modern beaded necklaces. Enamel, which is one of the oldest forms of surface decoration, is often arranged to create graphic, abstract patterns or cheekier winks, like miniature tennis balls on cufflinks. Even sparklier pieces, like diamond-encrusted earrings, bear an organic quality when arranged in the shape of a blooming daisy.

An innovative spirit can also be found in Jona’s collaborations, such as the partnership with Italian architect and jewelry designer Tiziana Redavid that yielded radical bracelets and necklaces made with stainless-steel springs. The result is a brand whose modern shapes and precious stones ride the line between traditional elegance and modern daring.
