Jewellery Care Guide

Sterling Silver: Gently polish with a soft jewellery cloth to maintain shine. Silver Care Guide →

Solid Gold (9ct, 14ct, 18ct): Solid gold will not tarnish or peel, but it can gather oils and dust. Soak in warm water with a drop of mild dish soap, then gently scrub with a soft toothbrush to restore its brilliance.

18ct Gold Plate: Avoid water, perfumes, and lotions to preserve the gold layer. Gold Plate Care Guide →

Bronze: Over time, bronze develops a unique vintage patina. Polish to restore brightness or leave to age naturally. Bronze Care Guide →

Gemstones: Clean with a soft, damp cloth. Avoid harsh chemicals or ultrasonic cleaners.

Frequently Asked Questions

Can I wear this on my pinky? Yes — the Kamahi suits a range of fingers. Select the size that fits the finger you have in mind; if you're unsure, get in touch and we'll help.

Is the sapphire natural? Yes. Both the blue and black sapphires are natural stones, heat-treated and cast directly into the silver face.

Can this be used as an engagement ring? Absolutely — the Kāmāhi makes a distinctive, modern alternative engagement ring. To complete the set, it can be paired with the Sylvan Band, a plain companion band custom-contoured to curve flawlessly alongside the signet's organic face as a wedding ring.

How long will it take? The Kamahi is made to order — please allow a minimum of 4 weeks from order to dispatch.

Style & Inspiration

The Kamahi takes its form from the same bubble-shaped lineage as the Selene Signet Ring — rounded, organic, and quietly bold. It's a ring that wears well every day and marks the moments worth remembering: a milestone birthday, a personal achievement, or simply a decision to wear something made for you.

The deep colour of the sapphire — whether the inky black or the rich blue — anchors the organic silver face and gives the ring a presence that reads as considered rather than loud.

Pairs beautifully with:

The Sylvan Band: Designed specifically to curve around the organic face of the Kāmāhi ring, creating a perfect nesting alternative wedding band set. Due for release in June 26.
