The "Valtiberina" collection is inspired from not so well known part of Tuscany , near the border with Umbria, and birthplace of great Reinassance painter Piero della Francesca.

The color combinations take their names from the most characteristic places of this regions: for example, the "Rocca di Anghiari" honey - black takes its name from a city deep in the Valtiberina, a citadel set in a fortress on a hill that oversees all of the valley underneath; or the "Nero di Catenaia" ("Catenaia Black"), where Catenaia is a mountain range that rises above the valley, full of woods so thick that it almost looks impenetrable.

The collection, made exclusively with italian resin, has gold parts refined with traditional tuscan goldsmithing techniques.
