UnoAErre Italia is a goldsmith, jewelry and watchmaking company based in Arezzo, Italy.

The company was founded on March 15, 1926 by Leopoldo Gori and Carlo Zucchi, in the city of Arezzo, with the idea to apply industrial methodologies to goldsmithing, aiming to minimize the costs of metal work.

The name UnoAErre comes from 1AR, the identification mark indicated on the punch affixed to products, assigned to the first goldsmith company of Arezzo (AR).

In 2008, the company revisited its practices to manufacture items that are lighter and that contain less gold and expanded into the production of accessories, rather than just sticking to traditional jewelry.

[3] UnoAErre also operates a museum with works of the artists who have collaborated in the production of its jewelry, including Pietro Cascella, Salvador Dalí and Salvatore Fiume.
