We perfected our wood rings creating the first tungsten Koa rings and passed that knowledge on to create the best titanium wood rings available. It all comes down to the koa wood. Sure you can find cheap "koa" rings with questionable wood, but we hand pick and finish our "curly" grained Koa from the Big Island of Hawaii. Why does this matter? Only the tightest (and therefore most rare and expensive) curly Koa will undulate in the light...the wood looks like it's moving. Pictures can't do it justice. Hawaiian "curly" Koa wood in a waterproof resin setting extremely light weight and 4x's harder than platinum 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 lightest band we make. The beveled edge tungsten is the original if you want more heft — see every profile in koa wood rings.
