Bulgari's B.zero1 collection is perhaps one of the most iconic in the world. The thick tiered bands have become synonymous with Bulgari, and can be spotted from a good mile away. Any changes to the iconic design must, therefore, be carefully considered. That's why Bulgari recruited legendary architect Zaha Hadid to redesign the icon. Hadid's design involved turning the parallel internal bands of the classic B.zero1 and turning them into a spiral. Doing so put a different spin on the pieces, and also allowed the brand to play with 'skeletonising' the ring's internal structure. Zaha Hadid might have left the world behind when she passed away in 2016, but her legacy lives on.
