About the Serpenti family
Serpenti is Bulgari's snake-inspired jewellery and watch line, with roots going back to the late 1940s. Its best-known form is the Tubogas, a flexible bracelet made from coiled gold or steel that wraps around the wrist, combined with a snake-head case.
The references in this catalog are mostly quartz, in pink, rose and white gold, some combined with ceramic, and many set with diamonds. Buyers check the Tubogas coil for dents and stretching, the condition of the stones and the case, and the bracelet size, as wrapped bracelets cannot always be resized easily.
