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).
Broken Oak is a handsome ring crafted from silver coloured tungsten carbide, and features a wood grain inlay and polished stepped edges. The inside of the ring is lined with a classy silver coloured finish, and the ring is topped off with a natural resin coat.
Our rings are lead free.
Featured sizes (comfort fit): N, P, S, U, W, Y
Please note: Bands cannot be resized after purchase - our ring sizes are an approximate translation from US sizing.

Each ring comes in a box, along with a 1 year warranty.
If we do not have a ring in stock, please allow 10-14 business days to craft a new one.
Note: All of our tungsten carbide rings are made with nickel-binder alloy. This is necessary to bind the tungsten carbide together. Nickel-binder alloy is hypoallergenic and chemically inert. It does not oxidise or cause rashes, or irritate the skin.
