Our Artisan Workshop
In the heart of Valenza’s goldsmith district, Sigillum Stones preserves and passes down the ancient art of glyptic engraving.
Our master engravers are among the very few in the world who still practice handcrafted engraving on hardstones, a technique dating back to Ancient Rome.
We transform agate, onyx, and carnelian into unique signet rings, heraldic coats of arms, and personalized monograms: bespoke works of art created to tell your story and remain engraved in time.
The signet ring is a timeless piece of jewelry that combines history, identity, and symbolism.
Originally created as a tool for authentication, today it is chosen as a refined and personal jewel.
Shape, size, metal, and above all the engraved hard stone (such as onyx, carnelian, and lapis lazuli) define the style and meaning of a signet ring.
Choosing a handcrafted signet ring means creating a unique object, designed to last over time and to tell a personal story.
