We started the tungsten & Koa wood ring trend and still make the most spectacular Koa rings available. It comes down to finding the most rare and expensive "curly" grained Koa wood on the planet. Sure, you can find cheap "koa" rings with questionable wood (we’ve been copied everywhere) but we hand pick and finish ours with Koa from the Big Island of Hawaii. Why care? Only the tightest "curly" Koa will undulate in the light…creating movement and shimmer…pictures really can't do it justice...that's why we added video : ) This design is an ode to one of our favorite sights in Hawaii...the lava fields of the Big Island. The large opening shows off the insane Koa wood grain.

  • Hawaiian "curly" Koa wood in a waterproof resin setting
  • comfort fit
  • lifetime warranty
  • Complimentary white glove exchange for proper fit
  • only dead or dying trees used...no need to feel guilty
  • Free and Fast Shipping...we make a bunch, send them to our shipping peeps in NC and they send it out next business day...for the win!
  • Thoughtful Gift, beautifully packaged for easy gifting...you just tell the story.

THE ORIGINAL KOA TUNGSTEN RING AND STILL THE BEST

We started the tungsten Koa wood ring trend and still make the most spectacular Koa rings available. Tungsten is the perfect base metal due to it's uncompromising toughness.  6x's harder than titanium makes it scratchproof. Our resin inlay process ensures a life-proof symbol of your relationship.

FOCUS ON THE KOA, OF COURSE

It comes down to finding the most spectacular Koa wood, period...and we spend the time. Koa has lent itself to create everything that is wonderful about the Hawaiian Islands and its culture.  From the first outrigger canoes and surfboards to ukulele's and warrior's weapons, Koa deserves its place as the cultural anchor of Hawaii.  We personally select our Koa Wood from dead or dying trees from the Big Island of Hawaii...that's the fun part.

AND PRESENTATION?

Yep, got you covered. Each ring comes in a beautifully created wood ring box.

Common Questions

What is the Sandblasted Gunmetal Koa Wood Ring? +

We use a sandblasted finish on gunmetal tungsten inlaid with exquisite curly Hawaiian Koa to create a ring worthy of your finger. The matte gunmetal finish makes the Koa grain pop with maximum contrast. Comfort-fit interior for all-day wear.

What is sandblasted tungsten? +

Sandblasted tungsten is tungsten steel finished with a fine abrasive spray, creating a matte textured surface. Tungsten is roughly 4x harder than titanium — scratch-resistant, doesn't tarnish, and hypoallergenic. The matte finish shows wear less over time than polished tungsten does, and it makes the curly Koa grain stand out with dramatic contrast.

Is the Sandblasted Gunmetal ring waterproof? +

Yes — fully waterproof for everyday wear. The Koa wood inlay is sealed within the ring which protects it against moisture. Safe for showering, swimming, dishes, and daily water exposure. For extended saltwater exposure, rinse with fresh water afterward and dry.

What sizes do you offer? +

US sizes 8 through 13, including half sizes. If you're between sizes, size up — These do not stretch. Free size exchanges on all rings. If you're new to ring sizing, visit any jeweler for a professional measurement.

How does the sandblasted finish differ from polished tungsten? +

Polished tungsten is shiny like chrome — reflects light, high shine, more traditional. Sandblasted tungsten is matte, textured, more understated. The sandblasted finish shows scratches less over time (because the surface is already textured), and creates dramatic contrast with the Koa wood inlay. Sandblasted is our best-selling finish because it complements the Koa best.

Can I return the ring if the size doesn't fit? +

Yes — free size exchanges on all rings. If your ring doesn't fit, contact us and we'll send a replacement in the correct size. The Koa wood inlay makes ring sizing a bit trickier than plain metal rings (Koa doesn't resize), so we designed the exchange process to be painless.

Is the Koa wood in the ring sustainably sourced? +

Yes. All Pono Woodworks Koa comes from dead or dying trees on private land on the Big Island — no live-tree harvesting. Only curly-grade Koa (less than 1% of available Koa) is used. Sourcing this way supports Hawaiian forest health and provides income to ranchers who protect old-growth stands.

What makes Pono Koa Rings better than all the other wood rings available? +

We started the tungsten Koa ring trend and still make the best. There's plenty of copy cats that don't use Hawaiian Koa wood (even here in Hawaii)…they usually use wood from Australia that looks similar. We can identify where our wood was harvested down to a couple hundred feet on the Big Island. We don't just use any Koa Wood, I waited 10 years for the current batch of curly Koa. The density of curl and depth of light shine just does not become available often.

Best memory

My husband and I had been looking for the right wedding band for him since we got married 3 years ago. We took a family vacation to Kauai in January and had a light bulb moment after we got back. This koa wood ring is the band we’ve been looking for. My husband gets to be reminded of our best vacation yet every day & think about all the great times to come. It’s gorgeous & holding up solidly even with his job.
