Abstract
A method of manufacturing a seamless hollow comfort fit wedding band is provided, where precious metal is flattened into a metal sheet from which ring-size "washers" are punched out at a press-machine. The seamless comfort fit look is then achieved by forming thin concave and convex shaped rings out of the "washers", which are later slipped into each other and soldered at their side edges to form one comfort fit wedding band.
