The Koa is a Hawaiian koa wood ring set in brushed black tungsten carbide with polished beveled edges — a koa wood wedding band that pairs one of the world's most coveted timbers with one of its most durable metals. The genuine Hawaiian Koa inlay shows a rich, chatoyant grain that shifts from dark coffee heartwood to radiant golden tones as it catches the light, and because every segment is cut from real timber, no two rings ever share the same figure.

Koa carries meaning as well as beauty: in Hawaiian tradition the word means "warrior," and the wood — once reserved for Hawaiian chiefs — has long stood for strength, courage, and endurance. That symbolism is why a koa wood wedding band has become a favorite for men who want a ring with a story rather than a plain metal loop.

The wood is stabilized and sealed before being seated deep in its tungsten channel, so the inlay is protected from daily moisture while the metal shrugs off the scratches that would mark a softer band. The dark brushed frame amplifies the warmth of the grain; the beveled edges add a clean, modern line.

Engineered from premium tungsten carbide for exceptional durability, your Regalia Ring requires minimal yet specific care. Maintain its finish by cleaning with mild soap and warm water, followed by drying with a soft, lint-free cloth. To preserve the ring's integrity, avoid contact with harsh chemicals or abrasives and store it separately when not worn; proper care ensures your ring retains its strength and refined luster for years to come.

Yes. The inlay is genuine Hawaiian Koa, one of the world's most coveted timbers, showing a rich chatoyant grain that shifts from dark coffee heartwood to golden tones. Because it's natural wood, no two rings are exactly alike.
Brief contact like hand washing is fine — wipe the ring dry afterward. Avoid prolonged soaking, swimming, and hot tubs, as standing moisture is the main thing that shortens the life of any wood inlay.
The Koa inlay is armored inside a brushed black tungsten carbide band with polished beveled edges. Tungsten's extreme hardness protects the wood's edges from impacts and keeps the band itself virtually scratch-proof.
No — tungsten carbide cannot be resized. Check your size with a ring sizer before ordering; if the fit isn't right, contact us about an exchange within the 30-day return window.
