Bulgari is not the inventor of Tubogas knitwear, yet whenever the term is used, the House of Bulgari is at the top of the list. But why? Because this knit has been worn to its greatest perfection by this brand. Its suppleness, despite its rigid shape, is the result of a great mastery of jewellery-making. Since its invention after 1850, Tubogas mesh has been used by a number of fine jewellery houses, including Van Cleef & Arpels, but the 1970s marked a turning point. The technique consists of winding two strips together, and the art lies in the fact that this winding requires no soldering! Initially adorned with antique coins, Bulgari's Tubogas jewellery became more complex by multiplying the rows or combining gold and steel - a feat of engineering! Rigid yet supple, easy to put on and take off on its own, this jewellery fits in with modern life and is very pleasant to wear.
