Bulgari B.Zero1: History, Style and Charm of the Iconic Collection
Architecture on the wrist: what makes B.Zero1 one of Bulgari’s most enduring designs
Few jewellery collections carry as immediate a visual signature as Bulgari B.Zero1. The central coil, the cylindrical body, the “BVLGARI BVLGARI” inscription on both edges — these are not decorative choices but structural ones. The result is a piece that needs no explanation. On the market for pre-owned regenerated Bulgari B.Zero1, this kind of visual clarity translates directly into sustained demand.
B.Zero1 attracts buyers looking for a first significant Bulgari piece, those completing an existing collection, and those who want strong design identity without ornamental excess. At ReLusso, every B.Zero1 offered for sale has passed through the Luxurigen™ process: authentication, restoration, and double sterilisation before listing.
The origins of the B.Zero1 collection
B.Zero1 was launched by Bulgari in 1999. The name states its intentions plainly: “B” for Bulgari, “Zero1” for a new beginning, a reset. This was not a stylistic update to an existing line — it was an architectural statement, a decision to treat the jewel as a structural object rather than a decorative one.
The direct visual reference is the Colosseum in Rome, understood not as ornament but as construction principle. The circular cross-section, layered volumes, compact solidity — these become the B.Zero1 coil, which does not adorn the piece but defines it. It is one of the few modern jewels that functions like a building.
The collection has evolved through notable collaborations. In 2010, Bulgari worked with artist Anish Kapoor on a version in rose gold and steel. In 2012, black and white ceramic variants were introduced. In 2020, the B.Zero1 Design Legend project — developed with Zaha Hadid Architects — pushed the original structure towards more deconstructed, asymmetric forms.

Technical characteristics and materials
A B.Zero1 ring is built around a central spiral band flanked by two flat edges inscribed with “BVLGARI BVLGARI”. Width varies by band count: approximately 6 mm for the single-band version, over 20 mm for four- and five-band models. All variants are available in yellow, white and rose gold, uniformly in 18kt (750/000).
Ceramic versions — black or white — feature inserts on the central coil that alter both weight and visual impact. A standard three-band yellow gold ring weighs on average between 10 and 14 grams; ceramic versions tend to be slightly lighter due to the composite material. Ring sizes follow standard Italian scaling, but band width affects fit: a four-band B.Zero1 typically requires one size larger than the same finger would need with a conventional narrow ring.
Select models feature diamond pavé on the rim or spiral, or coloured gemstones — amethyst, peridot, turquoise — that contrast with the polished metal. The underlying construction remains constant across all versions: cylinder, coil, inscription.
The main models
The Bulgari B.Zero1 ring is the defining piece of the collection, available in four principal configurations: 1, 2, 3 and 4 bands. The single-band ring is the most wearable daily piece; the four-band version makes the strongest statement. The three-band has historically been the most balanced option, combining visibility with practical comfort.
The B.Zero1 pendant and necklace translate the cylindrical structure into a suspended format. The standard pendant measures approximately 14 mm in diameter, carries the logo on its rim, and is available in the same gold variants as the rings. It is frequently chosen by those who want a recognisable Bulgari piece without the commitment of a substantial ring.
The B.Zero1 bangle comes primarily in two forms: a solid tubular bangle in continuous form, and articulated multi-segment versions. The rigid bangle carries the inscribed logo, requires no clasp, and fits wrists between approximately 14 and 18 cm.
Special editions — the Anish Kapoor version in rose gold and steel, the Zaha Hadid Architects pieces with deconstructed geometry — remain rarer in the secondary market but command consistently strong interest when they appear.
The ReLusso experience with B.Zero1
Among the B.Zero1 pieces that pass through ReLusso, three-band rose gold rings are consistently the fastest-moving — often sold within days of listing. Two-band yellow gold rings and rigid bangles follow closely. White gold versions appear less frequently in the regenerated market but attract buyers looking for a more restrained, urban aesthetic.
Price differences between variants in the authenticated pre-owned market are concrete and worth knowing before purchasing. A single-band yellow gold 18kt ring typically falls between €1,000 and €1,300. A three-band model ranges from €1,700 to €2,000 depending on year, variant and condition. Versions with diamonds or ceramic inserts start from approximately €1,200. The Anish Kapoor and Zaha Hadid Architects editions, being limited series, hold higher and more stable valuations.
Authentication checks specific to B.Zero1 include: quality of the “BVLGARI BVLGARI” inscription on both rims — it must be sharp, consistent, with depth perceptible to the touch; the 750 hallmark inside the band; symmetry of the central coil relative to both edges; and, on ceramic models, integrity of the inserts. Heavy wear on ceramic versions produces micro-chipping at the metal-to-ceramic junction that is almost invisible to the naked eye but clearly visible under a loupe.
One detail that only becomes clear after handling hundreds of these pieces: white ceramic B.Zero1 models show wear considerably faster than black ceramic equivalents, particularly at the junction points. This is not a structural defect, but it directly affects the aesthetic assessment during selection and determines what level of regeneration work is needed before a piece can be listed.
How to identify an authentic B.Zero1
The primary verification points on a B.Zero1 are specific. The “BVLGARI BVLGARI” inscription must appear on both rims of the ring or bangle, with uniform, well-defined characters. On genuine pieces, the engraving is not surface-level — its depth is perceptible when you run a fingertip along the rim.
Inside the band, the hallmark indicates 18kt gold (750 or AU750), accompanied by the maker’s mark. On pieces made for the European market, a country import control number is also present.
The central coil must be symmetrical and centred relative to both edges. On counterfeits in circulation, this proportion is frequently off — either the coil is too narrow or the rim widths are uneven. Weight is a reliable indicator: an 18kt gold B.Zero1 has a density that is clearly felt in the hand, something that brass-based imitations cannot replicate.

Frequently asked questions about Bulgari B.Zero1
What does the name B.Zero1 mean?
The “B” stands for Bulgari; “Zero1” signifies a new starting point. The collection was launched in 1999 as an architectural reinterpretation of Bulgari’s design language, with the Colosseum as its primary structural reference.
Which B.Zero1 models appear most often in the pre-owned market?
Two- and three-band rings in yellow gold and rose gold are the most common. Ceramic, diamond and special edition variants are less frequent but consistently in demand when available.
Does a regenerated pre-owned B.Zero1 ring retain its original quality?
When the piece is authentic and the regeneration process has been properly carried out, yes. ReLusso’s Luxurigen™ method covers deep cleaning, aesthetic restoration and double sterilisation — the objective is to return the piece to its best condition, not to conceal structural flaws.
How is ring size verified before purchasing a pre-owned B.Zero1?
Sizes are given in millimetres of internal diameter. A multi-band B.Zero1 ring typically requires a size larger than the same finger would need with a narrow classic ring. ReLusso always specifies the exact measurement for every piece listed.
