The Bvlgari B.ZERO1 collection is one of the most iconic jewellery designs of the modern era—an architectural masterpiece inspired by the circular form of Rome’s Colosseum and translated into a bold spiral silhouette. This 4-band mixed gold version in 18K white gold and yellow gold represents a rarer chapter of the B.ZERO1 story, where dual-tone precious metals create greater visual depth and collectibility than standard single-metal executions.
This is the discontinued mixed-gold 4-band configuration, a version that has become increasingly difficult to locate on the secondary market. Crafted entirely from 18K solid yellow gold and white gold, it delivers both substantial intrinsic value and unmistakable Bvlgari design identity. Unlike many contemporary two-tone jewellery pieces that incorporate steel, this example remains a full precious-metal execution, a distinction that becomes increasingly important to collectors. In today's market, the same budget often only secures B.ZERO1 variants incorporating steel, making this a particularly attractive acquisition for buyers seeking maximum gold content and rarity. Presented in mint condition with its original Bvlgari box, it checks the key boxes of desirability, scarcity, and long-term collectibility.
Most B.ZERO1 rings encountered today are either single-metal versions or newer configurations aimed at broader accessibility. This piece belongs to a different category entirely. The mixed white and yellow gold execution feels distinctly more luxurious in hand, and its discontinuation only amplifies that appeal. For collectors who understand the B.ZERO1 lineage, this is the type of reference that quietly disappears from the market and becomes noticeably harder to replace with each passing year.
