Black and white jewellery was at the height of popularity in the 1920s.

This onyx and old cut diamond plaque ring is a pleasing variation on the popular style usually seen with a single centre-set diamond.

Handcrafted in 18-carat white gold, it sits low on the hand in a fine but robust low setting with pretty fleur-de-lys shoulders.
