OroZen is the natural evolution of the CZ goldsmith company established in 1979 in Romano d'Ezzelino (Vicenza). Initially, Onorio Zen manufactured silver and gold medallions for the sports and religious sectors, but through small and innovative productions of high-end artisan-crafted jewellery, the company expanded its market share in Europe and the USA and adopted the 'OroZen' brand name in 2004.

OroZen's craftsmen create jewellery collections that delight consumers with their quality, their perfect styling, and their astute attention to detail. Shapes are simple, yet clean, and come in the form of chains, spheres, spangles, flowers, hearts, and crosses complemented with ornamental stones and pearls.

In 2001, OroZen was presented with a prestigious award from the Vicenza Chamber of Commerce for being a business that is distinguished by growth, as well as for tangible contributions to the improvement of Vicenza's community life. OroZen is present at the three Vicenza international jewellery trade fairs.
