Diamond ring, 1950s. This striking ring is the epitome of cocktail jewellery, which soared in popularity in post-war Europe and America. After the austerity of the second World War and the severe, mechanical late art Deco style that had preceded it, fashion and jewellery design in the post war period embraced a new, exuberant and feminine aesthetic. Cocktail jewels were designed for this optimistic new world, with large, attention-grabbing designs that were the ideal accompaniment for the party season. This ring, with its circular bombé-shaped design, is covered in approximately 4 carats of brilliant-cut diamonds spaced by ingenious faceted settings, creating a sparkling surface that perfectly embodies this glamorous aesthetic.
