Martin & MacArthur Koa Eternity Rings symbolize the strength of love and commitment. Our rings are made our private stock of Koa, from previously fallen Koa trees. We never cut down any Koa for our rings or furniture. 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. Martin & MacArthur Koa rings stand apart from all others because of our commitment to find and use only the best Koa.
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.
