Material
Typically 18K White Gold (Au 750); if an imitation, likely silver-plated base metal or sterling silver (.925). Higher-end versions contain ceramic or diamond accents.
Dimensions
Pendant approx. 15mm diameter. Standard chain length usually 15-18 inches. Authentic 18K gold weight is significant; plated versions are much lighter.
Description
An iconic piece of modern jewelry design, this necklace features the B.zero1 cylindrical pendant. Its architecture utilizes a spiral motif bordered by two flat rings engraved with the house's double logo, inspired by the Roman Colosseum.
Key Features
Spiral central coil, double logo engraving on the side rims, and the architectural 'cylindrical' form that mimics structural columns.
Material & Composition
Typically 18K White Gold (Au 750); if an imitation, likely silver-plated base metal or sterling silver (.925). Higher-end versions contain ceramic or diamond accents.
Finish & Decoration
Polished mirror finish with deep circular engraving. Features the signature 'BVLGARI BVLGARI' double logo engraved on the flat outer rims.
Hallmarks & Stamps
Engraved 'BVLGARI' on the pendant and chain rings. Authentic pieces would feature '750', 'MADE IN ITALY', and a lozenge-shaped factory identification mark.
Construction Details
The pendant is a central spiral (Tubogas inspired) held by two lateral rims. Authentic pieces feature smooth, high-precision assembly with high-tension coils.
Functional Features
Sliding pendant on a cable chain; feature lobster claw clasp; three-ring adjustable length system common in modern B.zero1 necklaces.
Handle & Grip Details
Lobster claw clasp for secure closure. Chain links are delicate oval cable style, uniform in size and strength.
Craftsmanship Details
Authentic pieces show no visible solder at the logo rings. Machine-precision engraving with crisp, deep letters. The weight should feel substantial in the hand.
Authentication Indicators
The logo font spacing (the 'V' should be sharp) and the 'U' written as 'V' in Roman style. Note: The presence of a white card tag and generic clasp visual may indicate a fashion-grade replica rather than 18K fine jewelry.
Origin & Manufacturing
Italy; high-end production in Valenza or Rome workshops. Known for utilizing the 'Tubogas' gas-pipe technique in its spiral design.
Era & Period
Contemporary/Modernist (introduced late 1990s), influenced by Roman architectural classicism and industrial design.
Age Estimate
Post-1999 production; the clasp and brand stamping suggest a piece from the last 10-15 years.
Cultural Significance
Represents the fusion of Italian industrial design with luxury heritage. It democratized high-jewelry icons for a younger, more trendy global audience.
Condition Notes
Very Good/Excellent. Light surface scratches visible on the pendant face. Chain appears intact with no visible kinks. No signs of major metal fatigue.
Value Estimate
$2,500 - $3,500 for authentic 18K White Gold; $50 - $150 if a costume jewelry silver-plated replica.
Care & Maintenance
Clean with a soft microfiber cloth. Avoid ultrasonic cleaners for versions with ceramic. Store individually to prevent the chain rubbing against the pendant rims.
