Ring design Hammered Smooth

Kio is a smooth brass signet ring with a wide flat face — classic in form, confident in scale, and available in a smooth and a hammered version. Also described as a wide signet ring or classic band signet for women. Made using sand casting, one of the oldest metalworking techniques: the shape is formed in sand and filled with molten brass, leaving each piece with its own character.

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. The shield is invisible. The durability isn't.

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.
