Mamba is a square signet brass ring — a clean flat square face on a slim band, minimal and precise. Also described as a minimalist square ring or geometric signet ring for men and women. Made using sand casting — a technique where the design is pressed into sand and brass is poured in molten — so each piece has its own slight character.

Made from solid recycled brass, finished with a nano ceramic e-coat that provides superior durability and resistance to water, sweat, and tarnishing. Wear it every day. The coating handles the rest.

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.
