Vintage Two-Tone Tubogas Necklace

This vintage two-tone tubogas necklace channels the glamour of the 1980s while paying homage to one of the most iconic design innovations in jewelry history.

Crafted in 14kt yellow and white gold, this necklace features the classic tubogas (gas-pipe) construction — a flexible, coiled form created without soldering, allowing it to move fluidly while keeping its sculptural shape. It sits right at the collarbone, hugging the neck in that sexy, effortless way that only vintage gold can.

The tubogas technique originated in Italy in the 1940s, inspired by industrial gas-pipe tubing — hence the name tubogas. Jewelry houses like Bulgari and Cartier popularized the style throughout the mid-20th century, celebrating its smooth, modernist lines and flexible movement. By the 1970s and ’80s, tubogas had evolved into a symbol of chic power dressing, adorning everything from chokers to serpent bracelets and watch bands.

This vintage example captures that essence perfectly — sleek, bold, and hefty. The two-tone accent makes it perfectly wearable with both yellow and white gold pieces, while the weight gives it that satisfying presence collectors love!
