  • Patent number: 6389846
    Abstract: A unitary prong setting for multiple gemstones and a multiple gemstone combination are provided. The setting includes a first set of prongs, each of which contacts and is adapted to fold over ends of two adjacent gemstones. The first set of prongs press the gemstones together and thereby securing the gemstones to the setting. Each of the first set of prongs is interconnected by a set of respective bars connecting each of the first prongs to a point substantially central to the first prongs; the first set of prongs presses the gemstones together and against the set of bars. The invention preferably further includes a second set of prongs projecting from the main base. The second set of prongs are adapted not to fold over the gemstones. The secondary prongs may provide ancillary support to the gemstones from underneath, or they may merely be decorative.

  • Patent number: 6116053
    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.
