This black tungsten ring features a crossed brushed finish center and polished edges for contrast. Tungsten carbides are in no doubt one of the strongest metal used in the jewelry industry. It is approximately two times stiffer than steel and twice the density. Our tungsten carbides are also cobalt-free which makes it hypoallergenic for most individuals.
Beautifully crafted with the Hawaiian koa, which is a exotic wood that originates from the Big Island of Hawai'i. Different parts of the island yields a distinctive hue to the color of the wood. The beautiful colors ranges from yellow or greenish-yellow, through orange, brown, and red, to almost black, and hues of different colors can be derived from a single trunk. In the Hawaiian language "koa" means "warrior" which symbolizes strength, fearlessness and bravery. From the ancient Hawaiian outrigger canoes to the birth of the first ancient surfboards and ukulele, the koa wood deserves more than ever be a widely recognized as a symbol of prestige and coloring.
