Black sintered tungsten carbide, Comfort fit and available in 2 inlay channel widths depending on what look you are interested in. I have created this line of Ash rings for my clients. Once ordered I will reach out to discuss sending ashes to me, I need very little (1gram, 1/8th tsp) and once I place the freshwater pearl in the rings I add a pinch of client ashes. they are then sealed up with resin.
I chose the Tungsten as my standard ring band as often these style of rings are worn on chains and I needed something exceptionally hard so as not to be worn, tungsten is only second to diamond in hardness but also is inert so as not to react to skin oils etc.
