Aloha, E Komo Mai (welcome). Komo Koa Jewelry is Hawaii's original authentic Koa wood inlaid titanium ring and jewelry accessory manufacturer. Since 2004, we have been combining two of nature's finest materials: Authentic Hawaiian Koa wood, traditionally used by ancient Hawaiians to make some of the first surfboards; and titanium, one of the earth's most abundant eco-friendly metals. The resulting wood inlaid jewelry is extremely light, comfortable, non-allergenic, eco-friendly and water resistant. Our durable wood finish is designed for daily wear in active lifestyles and carries an unconditional lifetime warranty just in case. Whether as wedding rings, engagement bands, fifth anniversary gifts or simply a special occasion, Komo Koa's Hawaiian Koa wood jewelry is the perfect statement of your affection for Hawai'i and each other.
