"In 1925, the Exposition Internationale des Arts Décoratifs et Industriels Modernes in Paris promoted innovative jewels in the style thereafter known as Art Déco, from the abbreviation of the name of the exhibition. These "modern" jewels were based on linear designs, stylised naturalistic decorative elements and gemstones of contrasting colours...

Bulgari kept abreast of the development of jewellery design. Towards the end of the 1920s jewels tended to become heavier and more massive, a feature which one can readily recognise in Bulgari's designs of the time, often set with coloured cabochon stones", as in the example offered here.
