Ring cores of Stainless Steel, Titanium, Ceramic, Sterling Silver, Copper or Tungsten may be selected in almost any size. The core may have one, two, or three channels allowing for a variety of wood, opal, or antler inlay to be added. Opal colour selection denoting birth months are a favourite. Antler has become the inlay of choice for men’s wedding bands. Engraving on the inside of a core is available.
