Martin & MacArthur Koa Eternity rings are made a continuous band of Koa from our private stock. This band of Koa does not have a beginning nor an end. It goes on continuously, for an eternity. Early Hawaiian believed that Koa symbolizes the strength of love and commitment. Martin & MacArthur only uses Koa from previously fallen trees. We never cut down any live Koa trees. The Company’s commitment to sustainability helps ensure Koa will continue to thrive in Hawaii for all eternity.
Martin & MacArthur craftsmen hand-select the finest of Koa for our rings. We only choose Koa with fluttering, curly grain pattern that reflect light at every angle.
We use rare Earth metals, Tungsten carbide and Cobalt. Both are extremely durable and highly scratch-resistant, unlike cheap Titanium metals. Keep in mind the resin finish on our rings will scratch, so please do not expose your ring to abrasive surfaces. Both Tungsten and Cobalt are hypo-allergenic and easy to maintain. Both require no polishing. Both will maintain brilliant shine forever. We engraved our Martin & MacArthur logo inside each of our rings as your assurance of quality and fine craftsmanship. If a ring does not have our logo, it is not ours. Martin & MacArthur Koa Eternity Rings have a one-year warranty from any manufacturer's defects. This warranty does not cover damage due to everyday wear and tear or dropping the ring.
