Not everything marketed as “koa” is actually genuine Hawaiian Koa. Learn how to tell the difference
Koa is one of Hawaiʻi’s most treasured natural resources—and one of the most beautiful woods in the world. But not everything marketed as “koa” is actually genuine Hawaiian koa. Knowing the difference is important when purchasing furniture, gifts, jewelry, or accessories.
Real koa grows only in Hawaiʻi. Acacia koa is endemic to the Hawaiian Islands. It only grows in Hawaii and no place else. By contrast, many products sold as “acacia” are made from commercial acacia species grown in Southeast Asia, including Vietnam, Thailand, Indonesia, and India. While some retailers try to sell these cheaper woods as Hawaiian koa, they are not Hawaiian koa. If it is too cheap, it's probably made from imitation wood grown in Asia.
One of the easiest ways to recognize genuine koa is by its extraordinary grain. Authentic koa often displays remarkable depth and movement, with patterns that seem to change as the wood catches the light. Its colors can range from warm golden tones to reddish and deep brown, frequently with dramatic contrasting bands.
Equally important is provenance. Ask where the wood came from and what species it actually is. A reputable retailer should be able to identify the wood specifically as Hawaiian Acacia koa and explain its source.
Certification
Consumers should also look for certified koa that provides documented verification of where the wood originated. Certification and traceability provide greater confidence that the koa is genuinely from Hawaiʻi rather than imported acacia being presented in a way that could be mistaken for Hawaiian koa. When purchasing an important piece, don’t hesitate to ask the retailer how it verifies the origin of its wood.
Just as important is how the koa was harvested. Choosing koa obtained from trees that have already fallen or died allows this extraordinary Hawaiian resource to be used without cutting healthy, living koa trees. Responsible harvesting helps protect Hawaiʻi’s remaining koa forests and supports their long-term regeneration for future generations.
Martin & MacArthur Certified Koa
At Martin & MacArthur, these principles are fundamental. The company uses certified Hawaiian koa with documented provenance and sources its koa from trees that have previously fallen or died rather than harvesting healthy living trees. This commitment provides customers with confidence in both the authenticity and responsible sourcing of the koa they purchase.
When you purchase genuine, responsibly sourced Hawaiian koa, you are buying far more than beautiful wood. You are owning a piece of Hawaiʻi—something authentic, distinctive, and impossible to duplicate with imported substitutes—while helping preserve the koa forests that make this remarkable wood possible.
