The price of gold has spiked in recent years and, as a result, the jewellery trade is quietly turning to other materials. Bronze, copper, titanium and aluminium are turning up in collections, whether from independent designers or established maisons, used not as substitutes for gold but for what they offer in their own right.“Gold has gone astronomically expensive and thus it shifts again in its perception and wearability,” says British goldsmith Joy Bonfield-Colombara, founder of Joy BC, who is one of a number of makers exploring the potential of non-precious metals.Gaze (Hazel) ring in bronze, recycled 925 silver and natural diamonds, by Joy BC.

Her Circle ring, one of the first she ever designed, was inspired by an antique Roman ring she wore through her teens. “I wanted to make it in bronze and patinate it in different colours,” she says. The result fell short of what she had hoped as modern bronze, as she discovered, contains a small amount of silica to slow its chemical reactions, with the consequence that patinas remain largely superficial and wear away faster than they do on antique pieces.Pottering Around bracelet in bronze, set with dumortierite and Palmeira citrine, by Cora Sheibani.

Unlike her experiments with rings, the bronze on the bracelets does not discolour the skin or react with the elements. “It made me realise how intelligently the Romans understood this material centuries ago, and how much more bronze deserves a place in contemporary jewellery today,” she says.For Bonfield-Colombara, bronze is the medium through which Japanese and European craft traditions meet. She first encountered Japanese metal patination as a student at the Glasgow School of Art, on a 2012 placement in the country under a master who taught her to make a Damascus steel knife. He showed her an Edo-period katana decorated with insects in bone, wood, coral and bronze.Cora Sheibani Pottering Around bracelet in bronze, set with Swiss pebbles, quartz and smoky quartz.

The Gaze series, made in 2023 for a Kyotographie festival exhibition with the photographer Olivia Rose, is the result. Two bronze brooches, later extended into rings, draw on the 18th century European tradition of lovers’ eye jewellery. One uses an Eastern patina with hazel diamonds, the other a verdigris finish, more associated with classical Italian and Greek sculpture.Hypatia (Small Green) pendant in bronze, by Joy BC.
