Koa Wood rings are designed for daily wear for all active lifestyles. What better way to test a native Hawaiian wood ring than go for a surf? Intense UV rays, turbulent salt water and gritty sand is no friendly environment for any jewelry. Hundreds of surfers and other water enthusiasts are wearing our rings daily as wedding bands. We make the most durable wood inlaid ring, hands down. And to back that up, we offer a lifetime warranty. We are continually testing our rings for durability. So when the surf’s up, it’s time for some R&D, or at least that’s what I tell my wife.
