Koa Wood (Acacia Koa) is found in Hawaii. The colour can be highly variable, but tends to be medium golden or red/brown (similar to Mahogany). The grain of Koa wood is usually slightly interlocked, and sometimes wavy. Tungsten is an extremely hard and dense metal. When combined with carbon alloy, it transforms into tungsten carbide. It is this durable tungsten carbide we use to craft our rings. As tungsten is so hard, so it is very difficult for a tungsten ring to get scratched (making it scratch resistant). Saigon is stunning ring is crafted from silver coloured tungsten carbide, and features a mixed media inlay. The inlay features Abalone shell, and Koa Wood.
