Unoaerre 18 Karat Yellow Gold Persempre Comfort Wedding Band - 3.5 mm

PERSEMPRE is the project through which UNOAERRE brings blockchain technology into the wedding ring. Not just a technological addition for its own sake, but a conscious choice: to make transparency a part of the symbol itself. The name stems from the desire to encapsulate in two words everything that a wedding ring represents, a mutual commitment that has no expiration date.

Every phase of this ring’s production process is recorded on the blockchain in a secure, permanent, and verifiable manner: the wedding ring becomes a traceable and certified piece of jewelry, capable of telling its own story. No step remains implicit, no information can be modified after the fact.

Access to that story is in the ring itself. The wedding ring is accompanied by a gold seal that can be personalized with an engraving and is equipped with a QR code: by scanning it, the couple enters a dedicated digital experience and can retrace the origin and journey of their ring, from the selection of the gold to the final checks. The seal thus becomes two things at once: a keepsake to be engraved and a key to be opened.

For PERSEMPRE wedding rings, UNOAERRE exclusively uses COC (Chain of Custody) certified gold, sourced from responsible origins in line with the standards of the Responsible Jewellery Council. Traceability therefore begins with the raw material, even before processing.

This version adopts the profile of UNOAERRE’s "Comode" (Comfort Fit) rings, whose rounded lines on the inside and outside of the ring ensure superior smoothness and comfort. It is made of 18-karat yellow gold, with a 3.5 mm wide band constant across all sizes; the weight varies with the size of the ring, from 4.95 to 5.65 grams.

Like every UNOAERRE wedding ring, it is born from a single casting of precious metal, pure and free of impurities, made without soldering: a manufacturing process that eliminates the structural weaknesses of joints and guarantees strength and compactness. The absence of interruptions in the structure of the ring is itself part of the meaning: a bond without points of fragility.

Produced in Arezzo by UNOAERRE Industries, the city's first goldsmith company, founded on March 15, 1926. Item code: 35 ABC1 col.01.
