Tubogas — Italian for "gas pipe" — is a goldsmithing technique Bvlgari made its own: thin bands of gold wrapped around a core to form a smooth, flexible tube with no visible soldering. Supple and sculptural, it has wrapped Bvlgari's bracelets, rings, necklaces and watches since the 1940s and remains a house signature.
What is Tubogas jewellery?
The signature is the seamless coiled tubular gold — flexible, smooth and often coiling in a snake-like wrap — across bracelets, bangles, rings, necklaces and watches, sometimes combined with steel, coins or coloured stones. It is made in 18ct yellow, white and rose gold. Genuine Bvlgari is signed Bvlgari, marked 750 and serial-numbered.
