Sina is a wave brass ring — a clean band with a subtle wave form pressed into the profile, minimal and precise. Also described as a curved band ring or organic wave ring for women. The sand casting process means every piece is unique — the form is shaped in sand and filled with liquid brass, leaving small natural variations in the surface.

Solid recycled brass, finished with a nano ceramic e-coat for superior durability and resistance to tarnishing, water, and sweat. 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.
