koa & Mother of Pearl
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 and it will retain its shine for a lifetime. 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 Black Tungsten, Koa Wood & Mother of Pearl Ring?
A dramatic take on our tungsten koa ring — polished black tungsten body with curly Hawaiian Koa wood AND blue mother-of-pearl inlay. An ode to the two elements that define Hawaii: the ocean (abalone/mother-of-pearl) and the aina (Koa). The black finish makes the Koa grain and pearl iridescence pop. 8mm width. Comfort-fit interior.
What is mother-of-pearl?
Mother-of-pearl is the iridescent inner layer of an abalone shell. It shimmers with blues, greens, and purples that shift with the light. Paired with the curly Koa's changing grain, the ring is essentially alive in the light — both materials look different from every angle. Genuine mother-of-pearl, not synthetic.
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 7 through 12.5 in 8mm width, including half sizes. Free size exchanges on all rings. If you're new to ring sizing, visit any jeweler for a professional measurement.
Why the black tungsten instead of silver?
The black tungsten finish creates dramatic contrast that makes the curly Koa grain and the mother-of-pearl iridescence pop. On a silver ring, the Koa and MOP are the star. On a black ring, the contrast turns them into the whole show.
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.
