About the price index B.zero1 Bague Bulgari
Launched in 1999, the **B.zero1** ring by **Bulgari** has established itself as a signature piece of the Roman jeweller, recognisable by its architectural silhouette inspired by the Colosseum and its stacked rings with an immediately identifiable design. The model exists in several versions, notably in yellow gold, rose gold, white gold, and pavé variants, which broadens its clientele on the pre-owned market. Its value remains strong because the B.zero1 combines a timeless design, strong brand recognition, and consistent demand for jewellery that is easy to wear and resell. Prices vary mainly according to the overall condition, the presence of the case and papers, the size, the series or edition, as well as the material and any settings. Examples in excellent condition, complete, and in the most sought-after metals, fetch better prices than pieces marked by use.

Reading the B.zero1 Bague Bulgari price guide
The range observed for B.zero1 Bague Bulgari runs from €1,200 to €2,500, with a median of €1,650 — a 2.1× gap between entry-level examples and the most sought-after ones. That spread is normal: on this model, condition, material and year weigh more heavily than the reference itself.
In practice, a piece below the median usually shows accepted signs of wear or a common configuration; above it you find rare colours, precious hardware and complete sets with the original box and invoice.
What pushes the B.zero1 Bague price guide up
- Gemmological certificate and perfectly legible hallmarks
- Original stones, setting never reworked
- Box, warranty and invoice from the maison
- Identifiable collection, still catalogued or archived
Selling a B.zero1 Bague Bulgari at the right price
We offer two options on this model. Outright purchase, settled within 72h once the piece is authenticated, suits anyone who wants an immediate exit. Consignment aims for the top of the range: the piece is photographed, promoted and sold with a commission that decreases with your membership card.
Signed jewellery keeps a floor value tied to metal weight and stone quality; the maison's signature and the presence of the certificate add the decisive resale premium.
