Robo is a quarter moon abstract brass ring — a sculptural crescent form that wraps the finger in an organic arc, the abstract shape giving it the quality of wearable art. Also described as a moon ring or abstract sculptural ring for women. Sand cast in brass: the mold is made in sand, the metal is poured in hot, and the piece that comes out is always slightly its own.

The brass is finished with a nano ceramic e-coat — superior durability and resistance to water, sweat, and tarnishing, without changing how the metal looks or feels. An invisible protective shield you wear, not a coating you see.

Care & FAQ +

What's the metal?
Solid brass with a nano ceramic e-coat for protection. Genuine, not plated.

Will it tarnish?
Highly tarnish resistant. The nano ceramic e-coating shields the brass from air and moisture that cause oxidation.

Will it turn my finger green?
No. The e-coating creates a barrier between brass and skin, preventing discoloration — and makes the piece hypoallergenic and nickel free, safe for sensitive skin.

Is it waterproof?
Water resistant, not waterproof. Fine for daily wear and hand washing. Remove before swimming or soaking to protect the coating long-term.

What happens over time?
Over time, the coating may gradually wear thin — revealing the brass's own warm natural patina, a beautiful evolution that's unique to your piece. Prefer the original shine? A soft cloth polishes it back in seconds.
