Tulle

A half-millimetre sheet of gold pierced by hand into hundreds of minute hexagonal cells, so the metal reads like net lace.

Bulgari

B.zero1

A spiral band that climbs the finger like the tiers of the Colosseum, held between two rims engraved BVLGARI BVLGARI.

One is pierced, the other built up. Mario Buccellati's tulle technique, born in the 1920s, saws a thin gold plate into a honeycomb of tiny cells until it reads like net lace, and still carries the house's eternelle bands. Bulgari's B.zero1, launched in 1999, stacks curved tiers of solid gold into a spiral. Tulle's openwork is fine and finished by an engraver's hand; B.zero1's tiers are bold and smooth. Each looks back to an Italian city, Venice for its lace, Rome for its amphitheatre.
