This hair pin is hand made from brass and blue oxide patina. It were inspired by the works of Alberto Giacometti and Ruby's graphic scores/musical maps.

Materials. Patina treated brass. Please note that patinas are ephemeral in nature and can chip over time to reveal the gold underneath. Something that we feel looks beautiful.

If you suffer from any allergies relating to jewellery or metals, and for how to look after your Ruby Jacks, please read our jewellery care page at the bottom of the home page.


Influenced by the shapes of hidden cities, caves, chamber choirs and catacombs, this playful pin looks stunning poking out of a top bun, or at the base of a neck, above a pony tail.
