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. Read the full Hawaiian Koa Wood Story →

Frequently Asked Questions
What is the Tungsten Koa Wood Ring (Beveled Edge)?
The design that started the whole company.. the tungsten koa ring with a beveled edge — a slight angled cut on the outer edge that catches the light. Curly Hawaiian Koa wood inlay in a scratchproof tungsten body. Comfort-fit interior for all-day wear. Available in 6mm and 8mm widths.
What is tungsten?
Tungsten is 6x harder than titanium — essentially scratch-proof, doesn't tarnish, and is hypoallergenic. It's the perfect base metal for a ring you'll wear every day for decades. The trade-off: tungsten shatters under extreme impact (like a hammer strike). That's a feature, not a bug — it protects your finger. In 12 years of making them, we've had less than 10 come back cracked…and of course we replace them for free.
Is the 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 4.5 through 13, including half sizes. If you're between sizes, size up — Koa wood does not stretch. Free size exchanges on all rings. If you're new to ring sizing, visit any jeweler for a professional measurement.
What's the difference between the Beveled Edge and Round Profile Tungsten rings?
Both share the same scratchproof tungsten body, curly Hawaiian Koa inlay, and lifetime warranty. The difference is the outer shape:
• Beveled Edge — a subtle angled cut on the outer edge that catches light differently and gives a slightly more modern, architectural feel.
• Round Profile — a smooth continuous curve on the outer edge, the classic wedding-band look.
Both wear the same on the finger (comfort-fit). Purely an aesthetic preference.
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.
LIFETIME WARRANTY TO MATCH YOUR LIFETIME LOVE
We stand behind all our creations and your ring is no different. Lifetime replacement should something go wrong... they're made to last like your relationship. We will also swap sizes with you free of charge until you get your perfect ring...because that's the way it should be.
