Mid-Century 18K Gold Tubogas Collar, c. 1950s, Italian Assay Marks

Supple as ribbon yet resolutely modern, this retro Tubogas necklace compresses coils of 18K yellow gold into a sleek, articulated collar. The low, even profile sits close to the clavicle, its continuous ridged surface catching light with a disciplined shimmer—an industrial elegance that defined mid-century Italian goldsmithing. Bearing Italian assay marks and measuring approximately 15 inches, the piece offers day-to-evening versatility: pared-back with a black knit, emphatic against satin.
