What defines a halo ring from the 1920s?

A 1920s halo ring is distinguished by its strict geometric symmetry, sharp angles, and the use of platinum or white gold settings. The central diamond is framed by concentric borders of contrasting stones, often incorporating calibré-cut sapphires or rubies in the manner typical of the Art Deco movement. These pieces prioritise architectural layouts over organic curves, frequently utilising millegrain edges and openwork galleries to maximise light entry through the cluster.

How do I wear an antique halo ring daily?

Living with an antique ring requires understanding the delicate nature of Edwardian and Art Deco settings, particularly the thin millegrain edges and fine claws holding the outer halo stones. While platinum offers strong durability, gentle cleaning with warm soapy water and a soft brush maintains the sparkle without straining the old cut diamonds. It is advisable to remove the ring during heavy manual tasks or swimming to protect the coloured stones and the structural integrity of the delicate platinum or 18ct white gold band.

What is a target ring?

A target ring is a distinct subset of the halo design where multiple contrasting rings of colour surround the central diamond. Typically, an inner ring of calibré-cut sapphires, rubies, or emeralds sits between the centre stone and an outer border of smaller diamonds. This concentric layering creates a bold optical effect on the finger, heavily associated with the avant-garde aesthetic of the 1920s and 1930s.

How do old cut diamonds differ from modern ones?

Old cut diamonds possess handmade facets that result in a chunkier appearance with a smaller table and a deeper pavilion. Rather than returning light in small, rapid pinpricks like modern brilliant cuts, they emit broad, warm flashes. This optical characteristic stems from the hand-polishing techniques employed by lapidaries during the early twentieth century before automated diamond cutting became standard.
