Some pieces borrow nature's straight lines; the Duna Brooch borrows its curves. Named after the wind-sculpted silhouette of a dune, it replaces the usual flat pin with something closer to an object — a chunky, organic ring of stainless steel that turns light around its whole circumference. Pinned to a lapel, a scarf or a plain tee, it does the work of a whole outfit.
Duna comes in two sizes, a compact Small for everyday wear and a bolder Large for statement styling, each in warm 18k gold plating or a cool platinum tone. Made from premium stainless steel, it is waterproof, tarnish-free and hypoallergenic.
Why You'll Love It
- Premium stainless steel that holds its finish season after season.
- Waterproof and tarnish-free — safe for sea, sun and pool.
- Hypoallergenic, so gentle against sensitive skin.
- A sculptural, organic ring silhouette with real presence.
- Two sizes and two tones to mix, match and stack.
- Secure pin fastening that holds on lapels, scarves and knitwear.
- A giftable object as much as a piece of jewellery.
How to Style It
Pin Duna to a blazer lapel for an instant finish, cluster it on a silk scarf for texture, or let it stand alone on a plain knit. The Small layers well beside other pins — the teardrop Gota Brooch or the pebble-shaped Costa Brooch — while the Large is better left solo. Mixing gold and platinum tone together gives the collected-over-time look that brooches do best.
Frequently Asked Questions
Will it tarnish or discolour?
No. Premium stainless steel does not rust, tarnish or discolour, even with regular wear and water exposure.
Can it be worn in the sea or pool?
Yes — the construction is fully waterproof and chlorine-resistant.
What is the difference between Small and Large?
Both share the same silhouette. The Large makes a bolder statement; the Small sits neater for everyday wear and for layering with other pins.
Duna — soft curves, holding their shape.
